Sonoff POW Elite Configuration

This is how i solved this part. You don’t need the lambda part… Now also working without load. (sorry don’t know how to publich the data in the way You people do

switch:
  - platform: template
    name: $friendly_name
    optimistic: true
    id: relay_1
#    lambda: |-
#      if (isnan(id(w_sensor).state)) {
#        return {};
#      } else if (id(w_sensor).state > 4) {
#        // Running
#        return true;
#      } else {
#        // Not running
#        return false;
#      }
    turn_off_action:
      - switch.turn_on: relay_off
    turn_on_action:
      - switch.turn_on: relay_on
  - platform: gpio
    restore_mode: ALWAYS_OFF
    internal: true
    id: relay_off
    pin: GPIO04
    on_turn_on:
      - switch.turn_on: relay_off     
      - delay: 500ms
      - switch.turn_off: relay_off  # bi-stable relay so no need to keep on.
      - light.turn_off: switch_led
    interlock: [relay_on]
  - platform: gpio
    restore_mode: ALWAYS_OFF
    internal: true
    id: relay_on
    pin: GPIO02
    on_turn_on:
      - switch.turn_on: relay_on      
      - delay: 500ms
      - switch.turn_off: relay_on  # bi-stable relay so no need to keep on.
      - light.turn_on: switch_led
    interlock: [relay_off]
  - platform: restart
    name: $friendly_name Restart

Hello
I confirm with these #lambda settings…
The switch works.
But after reboot or power outage it doesn’t show status in HA.

edit

is it possible to go back to the original sonoff firmware ?

Hi, you can go back to the original sonoff firmware via serial, but only if you have a backup from the original firmware. I have no problem with the status… Try with tasmota firmware, if you select he correct model all will run out of the box

Hello there,

I tried every trick in the book and then some.
My recently bought sonoff powr320D works fine with tasmota but not is esphome.
I tried even the basic CSE7766 Power Sensor examples. Esphome 2023.5.5 CSE7766 platform doen’t respond at all. It gives no readings. Not even in logs. I checked the chip on the PCB and it is the CSE7759B-SO.
Maybe CSE7766 platform it is not working properly with this chip?
Does anybody have any suggestions?

Hello, after debug uart on powr316 & reading CSE7766 datasheet, i add the line “parity: even” on uart config . Now i can view every electrical data. perhaps it can help you ?

Qtip · June 14, 2023, 8:50am

Perfect. That does the trick!!!.. Thanks Chris

uart:
  rx_pin: GPIO16
  baud_rate: 4800
  parity: even

mspiridakis · June 14, 2023, 9:34am

Thank you. I will try that. In the meantime I have tried a different approach.
It also seems to work commenting out the “baud_rate” line in logger.

logger:
  level: DEBUG
  #  baud_rate: 0

uart:
  - rx_pin: GPIO16
    baud_rate: 4800

sensor:
  - platform: cse7766

Qtip · June 15, 2023, 7:42am

Agree.

Even commenting out the the ’ level: DEBUG ’ line works.

logger:
#  level: DEBUG
#    baud_rate: 0

uart:
  rx_pin: GPIO16
  baud_rate: 4800
#  parity: even

I came across this thread after dealing with an issue of not being able to turn off the relay on my Sonoff 320D.

After looking at the code copied from Sonoff-POW-Elite-20a I came to the same conlusion that the Lamda code was the problem.

#      if (isnan(id(w_sensor).state)) {
#        return {};
#      } else if (id(w_sensor).state > 4) {
#        // Running
#        return true;
#      } else {
#        // Not running
#        return false;
#      }

I don’t know the rational behind the code but there is a serious problem with it.

If there is no current flowing you cannot turn off the relay. In my use case I am using this to switch on an immersion heater. If the immersion heather thermostat cuts power to the heater you cannot turn off the relay supplying power to the immersion heater.

I have updated the ESP code to comment out the Lamda code as other have done and now have proper control over the relay state.

what is the current recommended configuration for the sonoff powr320d ?

can you paste the whole yaml?

Chojino · October 27, 2023, 3:01pm

Hello guys, it’s been a year since I posted my config file, and I had to revisit it cuz I updated the EspHome version of the device and I lost all readings and I thought I could use my original post as a backup config, but was even better, chris1313 on post 25 solved it.

Apparently now you can find the config file on esphome website but google seems to like this post so here goes my updated config file with chris1313 solution and beaj improvement:
