Custom modbus energy meter not showing in energy tab

ESPHome
1

Hi everyone,

Im using esphome to communicate via modbus RTU with a Chint DDSU666 energy meter.

The communication part is working fine, but i cant seem to add the values to the energy tab. The sensor doesn’t show up on the drop down menu.

Can some one say what i am doing wrong?

Here is my .yaml file:

Could you read meter values in de log of the esp? I’m currently struggling with the same setup.
Did you managed to get this working?

Sorry for the late response. Yes i did. I had to reset the entities in home assistant. They were bugged.

Hi José, I also try to read from a DTSU 666, I’am using the Solar Inverters Stick, a Growatt ShineWifi X, to read from the modbus. I’am receiving the inverters states just fine, but the last sensor is the smartmeter and I never can get it to work. Modbus address of the meter is correct.

Hey,

I fixed the issue by doing this:

Hope that helps!
