Hi Ze_Pico,
I just flashed the Wesmo mini with Tasmota and configured as shown below.
- Tx on Wesmo connected to Rx on PZEM
- Rx on Wesmo connected to Tx on PZEM
==> The reading still show nothing. (Yes, I do have 110V AC to PZEM)
When connect:
- D8 on Wesmo connected to Rx on PZEM
- D7 on Wesmo connected to Tx on PZEM
==> Wesmo has no response, I can’t get into the Wesmo web interface.
I also tried to replace the Wesmo with NodMCU v3 and flashed it with Tasmota but the reading still show zero.
Here is the setup for NodeMCU v3:
- G on NodMCU connected to G on PZEM
- VV on NodMCU connected to 5V on PZEM
- D1 on NodMCU connected to Rx on PZEM
- D2 on NodMCU connected to Tx on PZEM
Would you please let me know what did I do wrong and how to fix it so the reading on show up on the Tasmota?
