Description
Several PZEM devices as Modbus RTU TTL slaves on single bus. Data collected by ESP8266 and pushed to GSheets for logging
Software is here:
https://github.com/executer-uno/Blynk-PZEM-004T-v3.0-Multiple-device/blob/master/README.md
Additional DC-DC used just becouse I had no 5V board mounted power source.
Modules stacked and connected to ESP board:
