DIY Home Power & Solar Energy Dashboard - Home Assistant w/ ESPHome

[@billkennard4310]

After messing with building my own with CT and esphome, with low stability, I made one using emoncms and ESP32 posting the Data to MQTT. Used the "integration" integration to convert the Watts to kWh and move it into the dashboard... DIY tip keep leads short between clamp jack and resistors/esp input, and beware of magnetic flourescent ballasts in close proximity.

[@garrox84]

Hey Bill, I also build my own monitor with ctClamps+nodemcu+emon-library. I also post realtime watts and amps to an MQTT topic. but what kind of integration do you use to get kw/h for the energy dashboard. i'm having a hard time dropping in nodes with all kinds of formulas in nodeRed. what is the "integration" integration?

[@billkennard4310]

The integration integration is a built in mathematical function in HA, I guess it is my only practical use for calculus!

[@TheBurnsStuff]

I know this may go against common practice, but this makes it easier for me. I wanted to share how I have my CTs labeled. For me, this is easier to know which CT is connected to which port without having to scroll back and forth. Thanks for all of these videos! This little energy monitor is really freakin neat!!! # Current Transformers: current_20a: '11143' # 20A/25mA SCT-006: 8x current_30a: '8650' # 30A/1V SCT-013-030: None current_50a: '15420' # 50A/1V SCT-013-050: None current_80a: '41660' # 80A/26.6mA SCT-010: 2x current_120a: '41787' # 120A/40mA: SCT-016: 2x current_100a: '27518' # 100A/50ma SCT-013-000: None current_200a: '27518' # 200A/100mA SCT-024: None

Thanks! Not a problem at all for throwing comments in your code or even substitutions of things to make it easier.

[@phillipzx3754]

Thanks for the tip ( at about 12:30 in on the video ) on crossing the lines on a 240 volt AC circuit. I was doing a "times 2" in the YAML. To change the currency go to the "General" under "Configuration." You'll see the Currency type. Edit and restart. Then the Energy dashboard will show the U.S. dollar.

[@digiblurDIY]

I do that in a couple of mine so you grab the real amps of both. Yes, that's just a test little dev container of HA, I wipe it from time to time and I just left it default.

[@RottieHaven]

@@digiblurDIY I'm confused about the crossing lines for 240V appliances/circuits - isn't the Current measurement accurate with a single line through the CT, but the Voltage needs to be doubled in the calculation for Power?

[@RottieHaven]

Could you explain where you're adding multiplication to your ESP32 YAML's Power calcs? Are you just uncommenting the 'Multiply by 2' under Power for a given CT?

[@digiblurDIY]

No, think about it. If you ran two 120v bedroom circuits through the same CT clamp you would measure the current in both of them. If you run both legs of an electric dryer in opposite directions through the CT clamp you can measure the current of both. it's still 120v per leg, they are just out of phase.

[@digiblurDIY]

Yes, if you want to multiply a value to change it from negative value, multiple by 2, etc the filters are great for that. esphome.io/components/sensor/index.html?#sensor-filters

[@hybrid.domotic]

the idea of the boy is original , even you video thank's big thumb !

[@alexsinbb]

Great video! Ordered the parts. Excited to get going! Planning on using 1 CT clamp on the generator back feed into the house to measure how many amps I'm pulling during a blackout too.

[@digiblurDIY]

Nice! I thought about doing that but I do have the Genmon project running on my generac.

[@dev45]

Nice update has got way easier then when I did it off your original video

[@digiblurDIY]

Indeed...things are always getting easier as we go.

[@AlexXHitchcock]

Us power is split phase. Meaning the resistance gets a single phase. A center tap transformed gets you the neutral leg that measured the 110-120V to each hot leg. Then reading across the hot legs gets you the 240v because you are reading across the full transformer. There for the two hot legs are in phase because they are the same phase.

[@digiblurDIY]

They are out of phase at least in my home. That's how it combines to get make 240v.

[@rtaussem9138]

Very cool video. I want to buy a 6-channel board, but I only find a power supply for the US in the shop of CircutSetup. Does anyone know which power supply to use for Europe with 230V and a different plug form factor?

[@JimfromIndy]

I dealt with the issue of ct's installed backwards by altering the templates to get the ABSOLUTE VALUE of the value. Works perfectly

[@digiblurDIY]

My OCD gets to me. But yes easily fixed via a template.

[@OldCurmudgeon3DP]

I put a little jumper on the main power to the ESP32 on my water heater. I can pull the jumper to program via USB.

[@DynamicJon]

Other cool thing might be to cover the 'use an entity with current price' in the energy config. Alot of people have TOU rates (4-9pm high energy cost, else low) - I dont see much documentation around that at the moment

[@digiblurDIY]

I assume that is left open to be flexible based on however you want to get the price into your system whether it be some automated way or manual method with helpers/automations. If I had that in would just drive it via a timed automation of some sort via HA or NR.

[@billkennard4310]

I put examples of my automations for this on the digiblur discord server under "projects and shares"

[@pjwlk]

Just a heads up for your Canadian viewers. It is illegal for you to install low voltage items inside your circuit breaker panel. Your home insurance may also be voided by doing so. Please consult a qualified hydro inspector or electrician to find out how to interface your system correctly.

[@digiblurDIY]

Highly recommend the electrician option myself as most places in my area do not have disconnects at the meter pan due to the close proximity of the main panel.

[@Just_An_Idea_For_Consideration]

Could this be used with Hall Effect Sensors - to monitor and log DC circuits such as Solar Panels and 48V Batteries Please advise

I have a couple of those WiFi antenna cables 20' long.

[@typxxilps]

is that device measuring apparent or real power cause the emporia suffers from the apparent loads that are partly wrong like all the induction driven motors causing the measurement errors ? Maybe I have not heard it in the video but I had some trouble with the emporia which had been showing 100 W for a inductive heater - on idle so nothing really going on. In reality it has drawn 2 W for the display / light and I guess some basics like the timer.

Thanks for this update. Loved your original video. Just at 07:30, where you mention the power factor and wattage are now done properly. Is this due to a revision of the board itself, or is the change just with ESPHome?

Cool (and timely) video - I'm looking at wiring up my panel and leveraging data I'm getting from solar to join together what I'm using and what I'm 'banking' with the utility. One question - I noticed that the vue sells 50a ct clamps (but with 2.5mm mono jacks) and was wondering if you or anyone in the comments have tried these - if so, did they work or what did you do to make them work.

[@digiblurDIY]

No idea why Vue or Emboria decided to screw with people on those 2.5mm jacks. You could try converting them or cut the end off and and do a screw terminal to 3.5mm jack.

[@marcusone1]

Would be great to update with showing how to setup the different clamps (change current_cal calibration per channel, which channels are where on the device, etc), or is that in your older video? :)

[@digiblurDIY]

I did cover that in the older one when we had to the calibrations ourselves. I would like to do a ground up one with plenty of room on the mains side or even with a cut off before the panel so I can show more on the clamp install hardware side. Hard to do that on a production house with an older panel that's a mess. I have some ideas....

Hi thanks for your time and effort put into your videos. I am considering getting this system. I have a micro inverter grid tie solar system and would like to monitor import and export values. Can this be done with 2 ct or would I need 4 cts so as to read bidirectional current flow? Any help or link to info would be appreciated.

[@digiblurDIY]

Thanks for watching my madness! I am not really sure about that as I don't have any solar experience due to costs. CircuitSetup would have more experience on that with the different setups.

[@MIKE-il6mu]

@@digiblurDIY ok thanks. I checked the circuitsetup site but didnt see any contact info. Is there a phone number for inquires. You could look at the sun gridtie inverters. Not very expensive. You can start with inverter and panels and add batteries later. Have a merry christmas and prosperous newyear.

[@digiblurDIY]

Check his discord server discord.gg/rw4sJfWv I would love to do some sort of simple grid tie system that would maybe produce 1000-1500 watts to help offset base usage. Tough to get anyone to mess with a small simple system as they want to install the massive ones but my net metering sucks at 2 cents kwh sell back.

[@DynamicJon]

You know what would be cool is if you could go over the config where you adjust the various channels by various clamps, like the whole house you mentioned you might use the 200amp clamps but then you also have the 20amp clamps.

[@digiblurDIY]

I think I did that in my previous version video and went through ground up calibration and such too since the cheats weren't there. Feel free to ask here or discord for details or help with your setup.

@@digiblurDIY yes its not disappearing..it never shows up in the list. The device and entity show fine and show stats in HA fine

[@digiblurDIY]

do you have the daily energy platforms and such set in ESPHome? github.com/CircuitSetup/Expandable-6-Channel-ESP32-Energy-Meter/blob/master/Software/ESPHome/6chan_energy_meter_house_solar_ha_kwh.yaml

[@ЕгорСушков-к2г]

Thanks a lot for great videos! Just a little question - could this be used to measure Direct Current?

[@digiblurDIY]

I don't believe this chip is designed for DC amp measurement. There are some other DIY projects out there for doing that.

[@ЕгорСушков-к2г]

​@@digiblurDIY From README: What you'll need: Current Transformers (any combination of the following, or any current transformer that does not exceed 1V or 720mA output) So theoreticaly we can use DC-DC hall transformer with 4-20mA output but need to find out how to calibrate it in source code for this board.

[@digiblurDIY]

Definitely hit up the guys at CircuitSetup as I just don't have any solar here. Missed my window of opportunity a few years ago for it.

[@andrewk2275]

Would this work with UK voltage, ie single phase?

[@digiblurDIY]

Yes it sure would.

[@Foxy10470]

Sir Its possible to generate analisys report to download the activities of all power consumtion for monitoring purpose?

[@digiblurDIY]

I don't see one on the dashboard of HA itself when using in that manner. But of course it is in the database of HA that you could acquire vis SQL. You can also export out the data to various methods using HA as the middleman.

[@Foxy10470]

[@chuhaohuang129]

Can u tell me the name of the development board which owns lots of 3.5 earphone ports? Or just tell me how to buy it. thx

thx bro@@digiblurDIY

[@petralandafamily3665]

Which esp32 with external antenna do you recommend? Can you paste the link of one please thanks

[@digiblurDIY]

Basically one like this...check the pinouts to make sure the correct pins are there though from wherever you get one. amzn.to/3vE503s

Anyone know how to get a hold of one of these in the uk?

[@leblancexplores]

Do all of these clamp style readers support dc?

[@digiblurDIY]

Don't know. I've never tried. I've only used it for AC

[@sundance2005]

Can this see what is going on with my Tesla Powerwall?

[@digiblurDIY]

I don't have any experience with this product but it will monitor the AC amperage/watts of whatever flows through the wire no matter the source.

[@JeffSwanson57]

I noticed in your video, that your clamps have really nice cables. Did you solder these on yourself? I find the ones from CircuitSetup are a bit short.

[@digiblurDIY]

I didn't solder any cables on. I used the ones that were there already on them.

[@JeffSwanson57]

@@digiblurDIY Ah, I guess that wasn't your setup. I'm talking about the cables at the 8:02 mark and again at the 9:47 mark.

[@digiblurDIY]

That is mine at 9:47 but the other is from the github on the CircuitSetup project. Crazy cables there. I suspect they are just extension cables.

[@lixxus-m]

is there anywhere i can get this board locally in UK ? or EU ?

[@digiblurDIY]

I don't think so. He does ship internationally from what I've heard.

[@hugobarbosa7753]

I come from the recent past. A week lost trying to make ESP32 work. Nah bro, there ARE coffee drip machines with timers. They come on or off when you need them to! Wall jacks that report energy consumption and remote turn on/off. etc. etc.

[@digiblurDIY]

Mine has a timer to turn on but stays warm way too long.

[@velbond007]

This board not available

He goes in and out of stock. Check the Emporia one kzbin.info/www/bejne/sGGtp2ekhJ6Cjck

@@digiblurDIY thanks

[@MrCraigCurtin]

I would recommend the IOTAWATT over the Circuit setup solution - it is much cheaper overall - a more mature solution and supports a wider range of CT Clamps

[@digiblurDIY]

I actually looked at that one myself a while back but bypassed it on the hardware choices used in it for various reasons such resolution, etc. I'm looking forward to see what they do on the esp32 model though when it comes out.

2x? Nah, I'd never go above 1.5x for ya, bro. 😜

[@jaredhelder]

Lol, yeah I do use 2x.

[@digiblurDIY]

I don't blame ya. They need to add 3 or 4 for myself.

[@mrechbreger]

Isn't that useless to monitor the amps of an AC line without monitoring the phase of the voltage, I wonder did you draw any conclusions about monitoring the current only for a year?

[@digiblurDIY]

Been using this product for more than a year and still like it. No regrets. I only have single split phase in the US and only need to monitor the voltage reference of the one phase available to us.

[@mrechbreger]

@@digiblurDIY ok so you are monitoring the voltage, I didn't see that in the video... so everything is basically just as I'd do it as well in Taiwan (we have 110V here). Thanks for your reply!

[@digiblurDIY]

Correct. It uses the AC to AC adapter for reference voltage
