Smart Plug Power Monitoring -Little Help?

ESPHome
,
1

Hi All, Firstly I’m very new to Home Assistant so please forgive me if I ask dumb questions but i’m getting there.

I wanted to get some Tuya smart plugs (Gosund UP111) running locally and with power monitoring in home assistant. I believe I have two options Tasmota and ESPHome.

I’ve managed to get Tasmota on a test device but this requires MQTT which I don’t have setup yet. So I looked at ESPHome, i’ve added the Home Assistant integration and compiled the following binary;

substitutions:
# Unique ID for Sensors.
  switch_id: "plug_washingmachine"
  # Higher value gives lower watt readout (0.0025)
  current_res: "0.00221"
  # Lower value gives lower voltage readout (880)
  voltage_div: "955"
    
esphome:
  name: ${plug_name}

Which was 99% stolen code from other posts and it validates, I’ve checked all the GPIOs against Tasmota and I think the platform and board are correct but Tasmato refused to flash OTA and when flashed through Tuya_Convert it bricked the plug, so something isn’t right!

If Tasmato is the way to go then I’ll persist with getting MQTT setup but for this use ESPHome does seem smarter and MQTT seems a bit of a learning curve.

Any suggestion, help would be greatly appreciated.

I thought there was an issue with my binary, there still might BUT.
Running ‘SetOption78 on’ in the tasmota console then allowed the ESPHome binary to be flashed OTA.

Hopefully thats all was needed and my logn winded post will be helpful for others.

No idea why Tuya_convert bricked the first device?! Same binary used via Tasmota.

Just an update for anyone that comes across this.
There seems to be an internal difference between Gosund UP111’s marked with 10A to those with 13A.
The 13A worked like a charm, the 10A ones I have refused to connect to my WiFi despite repeating the exact same steps. The plugs looked bricked with no response and not on WiFi ( no way to hard connect without cracking them open). But they simply won’t join my WiFi, think it’s due to special characters!?

To get them working I setup another AP and recovered tasmota by using the fast power cycle recovery. Joined to new AP (simple password), connected to console, set option 78 and uploaded esphome binary with real AP details in…all working.

Anyone know why a device with the exact same version of tasmota binary would take a password with special characters and another won’t?
