Open DavidAntonin opened 2 years ago

Hello, can you add support for multiple PZEM-004T modules? I would like to have full monitor of 3 phases of my house. Thank you

Hi @DavidAntonin, actually this feature is in my short-term list! I have 3-phase line in my new apparts, so I'm gonna need this feature by the time I move in. Not sure that I would be able to support old PZEM's, seems it's already out of sale now and I have only one of those. But I've already acquired 3 new pzem 004t-v3 modules and tested multiple access via modbus - it works pretty fine. So I would definitely work on 3 phase setup this fall. Keep in touch!

Thank you for your fast and positive answear. Yes, I have a pzem 004t-v3. I am looking forward.

a new library is available, designed to run multiple PZEM devices on the same bus. A prerequisite for 3-phase ESPEM rework. @DavidAntonin you might wanna test this.
