HOW TO create your own Low Battery Warning Sensor In Home Assistant - TUTORIAL

[@SmartHomeJunkie]

Do you know of any other ways to show the battery status of your devices? Let me know in the comments!

[@paul-tiberiumiclea1429]

Hi, yes If I go on state's and call any device with battery I see the value in the state

[@aaronjohnson8715]

In NodeRed: [MQTT NODE] -> [JSON CONV NODE] -> [FUNCTION NODE] var json=msg.payload.battery; if ( json < 30 ){ msg.payload = "Battery is running low on: " + msg.topic +", battery level is: " + msg.payload.battery; return msg; } return 0; This has an mqtt listener to "zigbee2mqtt/+", which then checks the battery level of all updates. When it sees one with battery being reported as below 30 it passes a message out to a push notification. A trigger in the path prevents multiple notifications within an hour. So far this seems to cover all of my devices, but an elseif statement could make this far more flexible if needed.

[@notfu9320]

I use the "auto entities" card from Hacs .. really quick and basically no code.. no helpers. Also use it to create a dynamic list to show motion or lights on my dash. Really clever card.

[@SmartHomeJunkie]

@@notfu9320 yes, that works as well. With the code in this tutorial you can also make sure that you get a notification on your phone when a battery gets a low value. I believe that cannot be done with the auto entities card.

[@AndrewGlasgow2020]

Another terrific video - and I was happy to buy the code. One very small correction: at 11:20 you reload the template file without restart. TEMPLATE ENTITIES only appears in the list after you have done one restart since adding the "!include templates.yaml" statement in configuration.yaml. So you have to do one restart (after checking configuration is OK of course). Then you can refresh TEMPLATE ENTITIES after any updates without a restart.

[@royahuis7458]

Great explanation. Watched a lot of your tutorials to improve my HA setup for my new house and I really like your videos! Thanks for making them.

[@rickz6006]

Thanks for this I learned a few things once again, glad I found this. When I decided to do a battery warning in HA I went Node Red. Took only 4 nodes an inject, get entities, format and call service. Batteries are checked every day at 3pm and a message is sent to my iPhone if any are low. New devices with a battery are included with no new code changes. The alert will repeat daily until the battery(ies) are replaced or charged as the case might be. Did a more complex version to do actionable notifications for low printer ink with the ability to mark the low ones from the iPhone once the replacement has been ordered. Keep the videos coming!

[@SmartHomeJunkie]

Yeah, I do have a low printer ink automation as well. The notification on my phone also leads me to an online shop to order the correct cartridges. It's just one click and I can order them. Life saver!

[@clairerovic]

Good Morning, another wonderful video. Really did like the pop-up that refreshed you on the data source i.e. the state attributes. When your trying to retain knowledge without a computer in front of you, it makes it so much easier. I have always call the file, sensor.yaml, is there any rules that I should be following or did I miss the memo.

[@SmartHomeJunkie]

Yes, there's a new and modern way of handling template sensors and that is by using the templates.yaml. The old way of using template sensors does not always work together with the new way unfortunately, so if you want to use the modern way, you should migrate all your template sensors to the templates.yaml and reformat the code a little bit.

[@SmartHomeJunkie]

Thanks! You can do that by filtering on the state of the entities. Filter on the state is low.

[@assistant-q4m]

Loved the video, agree with your view of only showing the batteries that are running low, but i have been trying to do one thing just as a visual preference, ( i must say i am a novice at HA ) i was trying to get the icon to show with the device name and percentage, i only wanted to have them visually show as either yellow or red, yellow indicating i have some more time before i need to take action and red when, ok you better go replace the batteries now. I tried everything i could think of in modifying this card and everything chatgpt suggested but got no where even with switching to different card types. Can you help if it is possible to do with the way you present them? Appreciate any input. Great work on the videos btw very detailed which is outstanding.

Hi Ed. The low battery template is great. Unfortunately I have some devices (Tado) that have binary sensors to indicate low battery. Its state is ‘normal’ or ‘low’. Is there any way to add this to the code? Cheers!!

[@Smoothy0911]

Hi and many thanks for this very interesting tutorial.👍 Well done 😄 I tried the "auto entities card", but have some problems to configure it for devices not using the device_class: battery (who use % as value) but the device_class: voltage, because I have devices running with 1.5V and others with 3.0V and so on... When creating the card and setting the threshold for ex. to 2.6V as alarm for all the 3.0V devices, all the batteries from the 1.5 devices are also listed as alarm... I hope you understand what I mean :) So now, I wonder if with your project, it is also possible to solve my problem, when using the device_class: voltage with different voltage levels for different devices and then also different thresholds (setpoints)? I think changing the code part in your project to use the needed class will be ok and running for voltage instead of %, but I'm currently stuck with the problembut how to show in the list only the batteries with a real alarm level, depending on the real operating voltage of the individual devices. At the moment, if the threshold is set to 10.5V as alarm level for 12V devices, all devices running with lower voltage will be shown as low level alarm in the list....!? These are the state attributes from one of my devices who do not use the device_class: battery but voltage: state_class: measurement interface_id: ccu3-webui-HmIP-RF address: 00365F29AC1C5D:0 model: HmIP-SWDO-2 entity_type: generic parameter: OPERATING_VOLTAGE function: null value_state: valid unit_of_measurement: V device_class: voltage friendly_name: Fensterkontakt_EG_Flur Betriebsspannung Thanks for any help and suggestions.

[@testguy3737]

As always very informative and helpful. I do have a few questions however, mostly related to the yaml code. In the earlier video "Templates and Custom Sensors in Home Assistant" the blocks are defined by "platform: template" with a sensors: token below it. In this video, the whole file is in the templates domain (I think domain is the right yaml term) and sensor listed below it. While the hierarchy seems roughly the same, the syntax certainly isn't and I find it confusing on which to use when. The other thing that confused me is in the templates.yaml file in this video, after the sensor: tag, the following lines are indented 4 spaces vs. the normal 2. I indented mine 2 and the sensor wasn't seen - when I also indented 4 it worked but I don't understand why. Any insight you have to these would help me in this mysterious land of yaml. Thanks again for all your good work.

[@markday3145]

Lots of useful hints here. Thanks! For this specific use case, an Entity Filter card seems like it would also work, and perhaps be a little simpler. You'd end up with something like an Entities card containing all of the battery entities with low charges, which has the advantage that they would display icons and percentages automatically.

[@SmartHomeJunkie]

Yeah, but what's the fun in that? 🤪 I looked into the auto-entities card too, but really wanted to have more control. Not sure what the exact reason was that I did not use it, but there was something that I was missing. 🤔

[@aldenyarde2194]

@@SmartHomeJunkie Interesting approach. Thanks for the info. I use the auto-entities card with a template filter to generate the list. It's a bit simpler and the exclude statement allows individual entities to be omitted (or multiple if you use a template in the exclude statement).

But wouldn't you need to update the list every time you add a new sensor? And it seems a bit annoying if you want a helper to define the threshold instead of a hardcoded value

First, thank you! I really appreciate the content you put out there. I'm using your more generic SDR version and it has been great! I would really like to be able to integrate a second/third SDR into the mix so I can pick up devices at multiple frequencies without having to time share the SDR. I cloned your repo to test changing the -d (SDR usb index) and can confirm that, after writing a new serial number to rtl_eeprom, I do not get error -6(?) where the integration cannot claim the interface. Seems like I CAN use more than one, but I don't really want to copy and rename/relink the repo multiple times. Any thoughts on how a hac like me could set up more than one SDR? Any chance your integration could support this? Otherwise, would you be willing to make a tutorial for creating our own HACS add-ons? Thanks again!!

Recently been looking at templates, but have experienced an issue where HA thinks the Template Integration is not installed. i dont see a way to install it in the integrations shop, any thoughts? have done some googling and looks like last year an update messed up templates for everyone for a while, has anyone has experienced this? and any helpful fixes?

[@SmartHomeJunkie]

I have no idea. It might be that you have an error in your configuration.yaml that messes things up.

it appears (for some reason) I can`t get this running .. if I take the code from IDE where I edit into TEMPLATES under developer tools I`m getting the following error: UndefinedError: 'jinja2.utils.Namespace object' has no attribute 'sensor' ... the code is fine I triple checked it and also the check config went fine, sensor is created however no matter what input value I set in the helper the low_battery_devices sensor returns unavailable ..

[@fredjaspers4364]

Ik heb de template code aangeschaft en alle stappen doorlopen maar helaas werkt het niet. Wanneer ik bij Entiteiten kijk en Low Battery Devices op zoek, dan staat er rechts een rode waarschuwingsteken dat de entiteit niet beschikbaar is. Heb een unieke id code gegenereerd en in de template code geplakt. Template entity opnieuw opgestart. Groene vink. @Ed, enig idee wat er aan de hand is?

[@SmartHomeJunkie]

Heb je naar de templates.yaml file verwezen in je configuration.yaml en HA daarna opnieuw opgestart?

[@fredjaspers4364]

@@SmartHomeJunkie Ja, ik had de template regel toegevoegd aan de configuration.yaml file. Wanneer ik deze na herstart weer open staat deze regel er nog steeds in. De enttity status blijft "'niet beschikbaar'' .

[@mikemitchelle1723]

Any idea why Low Battery Devices would have a state of unavailable when I have the threshold set to anything: 10, 50, 99 anything?

[@SmartHomeJunkie]

Check the attributes of your battery entities. It might be that they are different in your case. If so, adapt the code so that your devices will be included. .

[@Lordsheva80]

I did the same but easy with entity filter card.

[@SmartHomeJunkie]

Yeah sure, that can be done too! But... Did you learn anything about templates and custom sensors in the process? 😉

[@SmartHomeJunkie]

Oh and you can use this sensor in automations too. For instance to trigger a notification to your phone. 👍🏻

[@Lordsheva80]

@@SmartHomeJunkie well, I did an automation that looks at the state of entity and send a notification of less than x%.

[@SmartHomeJunkie]

@@Lordsheva80 Do you mean one automation for one entity, or one automation that uses a sensor that checks all the entities?

[@MrSupersidewinder]

Very helpful... THANKS!!!

[@SmartHomeJunkie]

You're welcome MrSupersidewinder (love the username). Glad it helps!!!

[@210Bubbagump]

It seems this does not work for any battery that does not have a value. For instance I have a device that has gone completely AWOL and the battery value is unknown. This then makes the conditional card not display for even the devices that ARE indeed below the threshold. Did I miss something or is this a limitation of the template logic?

[@SmartHomeJunkie]

The template excludes batteries that have a non number state. You can easily include this in the template yourself if you like.

[@210Bubbagump]

@@SmartHomeJunkie Then I must have missed a step. Very cool. Thank you!

[@SmartHomeJunkie]

@@210Bubbagump I don't think you've missed a step. I guess your battery sensors have different attributes than mine.

Gone through this a few times, and its not generating a "Low Battery Devices" sensor.

[@brianh.4185]

I also am having this issue. Your template code on github does not start with - sensor: as you indicate in the video that it must, however I have both included and excluded this line from templates.yaml and it makes no difference; I do not see a "Low Battery Devices" entity via developer tools. Any idea what is wrong?

[@SmartHomeJunkie]

Did you restart Home Assistant after adding the templates.yaml redirection line in the configuration.yaml?

[@brianh.4185]

@@SmartHomeJunkie Yes, and the Template Entities item appeared on the Yaml Configuration Reloading list where it did not previously exist.

@@brianh.4185 Ah okay. Well it's hard to say why is not working at your side. Other people don't seem to have issues with it. Maybe the log files might give you a clue? Or, but this is a blind guess, you might have set HA to a different language and the entity name might be different because of that? 🤷🏼

Yes, I think so. Please make sure that you do not have other template sensors in your configuration.yaml or sensors.yaml. Storing template sensors in your templates.yaml only is the modern way of doing this.

@@TalZac Did you restart Home Assistant after that? Do you also have a sensors.yaml file maybe that contains sensor templates? If not, I'm not sure what might be wrong in your setup. I think it should be something with having sensor templates defined in multiple files.

{% - ... - %} => what are the "-" for? there is no documentation on this one

[@SmartHomeJunkie]

Is to keep "the code together". If you check it in the developer tools, you will see that if you do not use the dashes, each code line will take up space in the generated output. I don't think it really makes a difference in templates though.

[@JoseBerruezo]

Great video, but I would like to see a video that tells me how long the battery lasted.

[@SmartHomeJunkie]

Thanks. I think with the info in this video you can build this yourself. You'll need a helper for each battery to store the date and time when the battery was installed / charged to 100% probably, but it shouldn't be that hard to create.

[@Shellyfi]

Biggest problem is to know when new battery was installed or device have taken originally in use. You need to define install /recharge for device

@@Shellyfi Yes. I believe you can store that in a helper.

Hi Ed, being a software noob, I am struggling, i get an error. (the brief error description here, the full description below) (TemplateSyntaxError: Encountered unknown tag 'ns'.). I have done several investigations but cannot drill to the solution of the issue. I use two types of interfaces, Zigbee and RFX (the old "klikaanklikuit") that have batteries. The zigbee has "state" =(battery level), "device_class" and "state_class" The klikaanklikuit have these also. I have checked the developer console and found that (in my sample) the filters regarding the attributes are valid, so that should not be the issue. I have checked the develop template to check the code, but it provides the same issue. I checked the Jinja template expl. document, does not provide the solution. What to investigate?? The full error msg: 2022-12-29 18:10:54.843 ERROR (MainThread) [homeassistant.config] Invalid config for [template]: invalid template (TemplateSyntaxError: Encountered unknown tag 'ns'.) for dictionary value @ data['sensor'][0]['state'].
