Home Energy Monitoring made easy
For NodeMCU Energy Monitor (PCB/Kit)
Before I found this home energy monitoring solution I didn't realise it could be done so easily. I was using Thingspeak already for water tank level monitoring and this design fit right into my home monitoring dashboard and Tisham has it setup ready to go wit thingspeak you just need to put in your api key.
I didn't know anything about energy monitor before getting this kit, I had played with Arduino and other IoT solutions before though, so it took a bit of reading into what power factor and real power was, and now I kind of understand it.
The kit was super easy to put together, I ordered the current clamp from china and went with the din rail transformer installed into my power box for a nice clean solution, once I realized the AC reading was need to determine real power.
The graph is really interesting to watch in thingspeak, with it spiking for things like the toaster, Iron and aircon, and surprising the TV doesn't make it go up a great deal at all.
Perfect simple solution, I didn't think a energy monitoring solution could be this simple and integrate into my existing dashboard, but it does and I highly recommend you try it out.

Thanks a lot for the review. It is fun to watch the data stream and actually get an appreciation of what consumes how much.

Thanks a lot for the review. It is indeed fun to watch the spikes and troughs and get an appreciation of relative usage of various appliances. I have tested an SSD1306 OLED display and that works as a local display of instant power in addition to the time series on thingspeak.
