Smart energy meter DIN rail

mauog · March 30, 2019, 10:09am

Hello,
I’m looking for a smart energy meter to be placed on a DIN rail compatible with home assistant (in any way) of course.
I installed some Innr zigbee plugs to get consuption from some appliances now I would need something that could be able to monitor “all the rest”.
Thank You for your suggestions

Regards

M.

Shelly 4 Pro - 4x10 amp switches + power consumption information via wifi
SDM120M - power consumption information via modbus (need modbus USB converter)
you can also see some other products from their site which may fit to your needs http://www.eastrongroup.com/products/10.html

If you are familiar with diy projects, I can recommend for you:

and of course you can put all in the DIN riley casing:

Is there any component or custom component to monitor the wattmeter output in a HA graph?

Is something like this what you want?

How did you mesure the power consumtion?

I’m using now 2 approaches simultaneously:

A PZEM-004T v3 connected to an ESP8266, measuring the main phase current and power consumption;
A RS485 converter connected to another ESP8266, reading the EDP smart meter values in realtime. Check it here: https://github.com/tiagofreire-pt/Home_Assistant_EDP_Box

A ZMAI-90 ?

They work real well.
