Cheap solution to monitor individual circuit on the electrical panel?

[Banshee1971]

Is there any solution already compatible with Domoticz to monitor individual circuit on the electrical panel?

I have Domoticz on my Synology NAS.

The only solution I found are 2 Amp clamp kit.

I want to monitor the Water tank, dryer, pool thermopump and house thermopump. And some other stuff

Check out the i2c interface products from NCD.io (current monitors). I have a 4 channel one in my fuse box connected to a dedicated pi and it works with Domoticz. They provide a python script.

'Cheap' is of course a relative thing. The 4-channel ncd.io with i2c costs $75. Four of those chinese babies will be $16. You can't exactly buy a new car from that difference...

The minimum solution, 6 donuts. The ideal ; 21.

Do you have any website or description on how to build a 21 donuts solution?

And instructions? Parts list,..

Now how we connect it to domoticz?

Using the http client library in arduino for the ESP8266, post to a json url endpoint corresponding to a meter or switch. Google is your friend.

Why messing around with libraries ?

1 stop software/image to connect to Domoticz and reliable results.

I found the iotaWatt project on Github. It's a 14 Chanel monitoring using mqtt.
Anyone tested that?
Sound promising.
