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

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

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.

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

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.

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.

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.

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

I very appreciatte your video and your boy saying to subscribe.

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.

Great video thank you, With the information provided, really simplified the project. Still trying to figure out how to monitor battery capacity, charge and discharge. Might hit you'all up on discord. 😎

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.

ohh liked, i dont want to be flooded.

I alway wondered why I used Node-red, now I know. More detail would be good.

Thank you, always very well explained !!!!:pride-unicorn-rainbow-mane:

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

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.

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

Great video thanks. For the solar monitoring are you using post inverter, therefore measuring AC? I'd like to measure the PV DC and not sure the Current monitoring works for both AC/DC feeds.

Great video, thanks. To add an external aerial do we need a different version of the ESP32 NodeMCU, to have a aerial connector? Also can you recommend a aerial.

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