Node Red + Home Assistant -Master Class 5. How to control light dimming with Zigbee light and remote

[@TimNorman1]

This helped explain to me the process of getting the dimming to work. I have a Hue Phillips dimmer switch and was trying to figure out from pictures how others got it working. This helped bridge that gap for me. Thank you

[@FloorVerschure]

nice tutorial. Well explained. You can tell that you've put a lot of effort in the way you tend to explain everything. I did use the Ikea multi-button remote with a regular light group. This light group does not have a sensor with brightness to query, but there is another way: In HA light objects have their attributes stored in: msg.data.attributes You can find the parameter brightness there. Therefor I can simply remove the additional brightness node and replace "var brightness = msg.payload" with "msg.data.attributes.brightness = msg.payload" in the function nodes. as such I can use it with any light or light group in HA (Which has dimming support). Maybe this helps others who do not have the same setup and make the flow a bit more universal.

[@HomeSight]

Good stuff! Thanks for the tip!

[@d_sellers1]

Your comment is what helped me get this function working. I, too, was having issues with getting the brightness value in/out of the function since I do not have sensor values. However, I believe there is a typo in your comment. It should read as: ...replace "var brightness = msg.payload" with "var brightness = msg.data.attributes.brightness" in the function nodes.

Great tutorial. Looking forward on additional ones regarding node red.

[@HomeSight]

Glad you enjoyed it!

[@jenswymeersch9653]

@@HomeSight I read you were thinking of an add-on to these master classes. I believe the most useful is a session specific on the function node and use of JSON/JS for Home Assistant.

Thanks for the detailed explanation learned few things from your tutorial videos, expecting more videos about Home automation with HA & Node RED integration...

[@HomeSight]

You are very welcome!

[@drreality1]

Such a powerful and easy to follow tutorial 👍 I actually have the automation with Ike's buttons, however instead of trigger nice I used delay node sending a single message each time and ignoring messages in between. Yours look much easier to debug Amazing work

[@HomeSight]

Thank you, I remember looking for flows to import when I first started out, and imported some that were massively over complicated. I aim to keep it simple!

[@RogerStocker]

Hi Simon You are a good teacher and you do amazing nice things with Node-Red. I realized in one of the videos that there have been a lot of Shelly messages in the debug window. So I'm looking forward to see how you manage this pieces within HA. by intergating the Shelly entities or by switching to MQTT and using this "new" feature in the Shelly settings.

[@HomeSight]

Thank you. Yes I use quite a few Shelly devices, I’m a big fan of their devices. There will certainly be some videos on using Shellies with HA!

[@v2gagao]

NICE TUTORIAL, I would like to know how to use the side buttons (left and right) of the same IKEA switch to change colors randomly of the bulb.. please share some details around it.

[@HomeSight]

Hi, I don’t have any colour changing bulbs, but I do have some Shelly RGBW2 and a flow which allows random colour selection, so I can do something with that! I’ll get on it! Thanks for watching.

[@alejandrolazaroZS09011386]

Que buen tutorial me ayudaste mucho !

[@philou1516]

Very nice tutorial, thx ! In the case I have a simple switch with only one hold action (and not one up hold and one down hold I mean), is there a way to switch between increase/decrease each time I release the button, please?

[@robmiller3246]

Love Your videos, I have learned a lot from them. Did the Ikea button work right of the box? I have a aqara mini button and am having an issue getting it to work with this automation

[@tpenick]

Great videos, they've really helped me a lot in my setup! One question though, is there a reason to check the light state first and then use the "turn_off" action if on and vice versa, as opposed to just using the "toggle" function? Does it help with efficiency?

[@dougle03]

Would be great to see best methods to use sub flows to simplify this for reuse?

[@HomeSight]

Sure, I’ll add it to the list!

[@Frosty_CubeZ12]

Hi there. Loving these tutorials, (slowly) learning a lot. I'm using the same Ikea Multi switch + Tp-link bulbs, I can get on off to work & it will dim up and down but not in steps, they go to max & min. I've been over and over it making sure I have everything as it should be according to the tutorial but no joy. Any pointers would be much appreciated. Cheers.

[@thebatu89]

Excellent tutorial! Since i only have the aqara button (1x,2x,3x,4x clicks, hold and release). Is there a way to include both dimming up & down for the same hold action?

[@HomeSight]

I guess it’s possible… just working it through in my head, I think I would check to see the current brightness then go down an “up” route or a “down” route, with down of its greater than 50%. I’d have a node either increasing or decreasing the brightness by 5% in a little loop with a current stater node which would check if an input Boolean is true. On the release of the hold you’d set the input Boolean to true, then kick off a delay of 5s to set it to false again so it’s ready for the next fade. Does that make any sense?

[@thebatu89]

@@HomeSight hi yes, I can see that but I'm not sure yet how to add them in a function node since I'm still a beginner. I also just figured out why reset node wasn't working which keeps the trigger action keep increasing the brightness. Seems like z2m occasionally doesn't pickup the release action from my aqara button. Have you add similar issues with aqara if you have one?

[@HomeSight]

I have various Aqara devices including the mini button you’re talking about. I’ve never noticed a missed release, but don’t actively use that function on a day-to-day.

[@thebatu89]

@@HomeSight Is there a node that I can use to limit the payload sent to increase brightness if z2m didn't receive the 'release' action? Also do you mind sharing your own flow of checking the current brightness if less or more than >50% with the input boolean check?

[@MrBobWareham]

Hi can you use Node-Red with MQTT to make a small setup as I don't need Home Assistant I only have a few sockets, Sensors, Doors but would like to automate some things and not use EweLink so HA is overkill I use ESP8266, ESP32-CAM, AND SOME 433Mhz radio, thanks for sharing the course it is very good

[@HomeSight]

Hi, yes you absolutely could. Although you would still need something to run your MQTT broker (Probably Mosquitto). Are you familiar with docker at all? Because that could be a good solution running a docker image of mosquitto is fairly straight forward (dependant on level of course)

[@didactics]

Dude, you saved me. Awesome job

[@HomeSight]

Glad to help. Thanks!

[@jj123456789000]

Hey Simon! I used you tutorial and it work very well! I "pimp" a little the flow, so all the variables are define at the begining and also all the entities (you can put multiples light). I also add a random color changing (but my light are tuya, so the rgb stting dissapear for no reason). Also when you hold and release the arrow it goes full warm or full cold. Do you want the flow (copy/paste from node red)?

[@HomeSight]

Great stuff glad it worked for you!

How do you get/set the bulb color temp? Is there going to be a Master Class 6?

[@HomeSight]

Hi K G, yes there will be a Master Class 6. Still not quite sure what to do it on yet, I was wondering about showing how to do home occupancy.

[@HomeSight]

Sorry, I missed your other question. You need to see what your bulb supports, as there is multiple ways that colour temp can be used a common way is as below using "color_temp" . Other ways can be "white_value", "color_name" or "hs_color". { "entity_id": "light.YourEntity", "brightness": 50, "color_temp": 50 } Hope this helps!

hey. is there a recommendation to have a AND button. I would like to add if I where to press toggle and brightness up together to preform a action like toggle on with full brightness.

[@HomeSight]

Yeah, kind of. I would use a wait node.

[@RandomGuy-lm8wh]

First of all, thank you for the great video`s you made. There are absolute the best on KZbin! The only thing I don't get right in this video is that I can't see or find any brightness entity on my lights. I want to increase the brightness of one specific lamp when my Nvidia Shield is paused during the night. I got everything working, except for the brightness part. So how can I get this to work, or how do I get the Brightness entity of (in this case) my light.kitchen entity?

[@HomeSight]

Hi, that’s very kind of you to say! I don’t like having to split down JSON in my node red flows unless I can help it, so I strip it out and set it as a sensor in config.yaml. Here’s an example for you: - platform: "mqtt" name: "Bedroom 1 Brightness" state_topic: "zigbee2mqtt/bedroom1" availability_topic: "zigbee2mqtt/bridge/state" icon: "mdi:brightness-5" value_template: "{{ value_json.brightness }}”

[@dave-j-k]

HI, great video and answered a lot of questions :) I'm using a Hue 4-button dimmer but have a group of 6 zigbee bulbs - all works fine apart from the long press up/dn which sometimes works but can crash the dimmer action somehow - it seems there is a big delay in updating all the bulbs?? I have read it could be something called zigbee command flooding?? and I should create a zigbee group which acts as one entity, trouble is I can't find how to do that in ZHA - any ideas??

[@HomeSight]

Hi and thanks! I've not seen the issue with crashing or delays... i haven't found ZHA to be the most useful in terms of logging etc, I primarily use zigbee2mqtt, which does give some pretty good logs so you can see what's going on... not sure that helps you though?!

[@hugovalderrama9768]
