Trying to create a config for BlitzWolf BW-SHP7 (double smart plug)

ESPHome
1

Hi All

I have a SHP-7 here that I’m trying to set up with esphome.
If I look at the Tasmota template repository, I get this pinout for SHP-7:

So by modifying the SHP-6 esphome config, I got this:

substitutions:
  device_name: doubleplug
  # Higher value gives lower watt readout
  current_res: '0.00025'
  # Lower value gives lower voltage readout
  voltage_div: '940'

esphome:
  name: '${device_name}'

The relays are shown in HA, and I can turn them on and off from HA.
What does not work yet:

LED2 doesn’t turn on / off with the relay.
BUTTON1 doesn’t trigger the RELAY1
BUTTON2 doesn’t trigger the RELAY2

It reads out powerconsumption, though I’m not sure if the chip I put in the config is the right one?

Any ideas on what I did wrong here, it did work work with tasmota?

Hmm, if I change LED2 to use GPIO01, but then it shows a blue led (link) instead of a red one for the relay.
