Power Switch shows wrong status after power loss

ESPHome

Hi,
I have a Gosund SP111 power switch on my fridge for alarm purposes.
After I found out, the power switch is always off after power loss (whch is not good on a fridge for obvious reasons) I didn’t want to store the previsous state on its flash since it wears out the flash.
However, I added:

esphome:
  name: $devicename
  platform: ESP8266
  arduino_version: 2.5.1
  board: esp8285
  on_boot:
    priority: -10
    # ...
    then:
      - switch.turn_on: relay

This works, the switch is on after a power loss.
However, the status in home assistant shows the device as “off”. If I click on it, it shows as on, without triggering the switch (it just stays as is). After that, everything works normally.

How can I get the correct on/off state after power loss?

2

Why not set restore_mode: ALWAYS_ON on the switch directly?

3

Thats the same result, the switch is turned on but initially shows as “off”.

4

Can you show your relay config?

You could also try decreasing the priority (try -100) to make sure everything is ready so that the state can be sent to home assistant.

Yes, sure, thanks.
I will try!

Still shows as off with -100 :frowning:

Your switch has no state feedback from the relay. That’s why it is getting out of sync. Instead of using optimistic: true use a state template:

switch:
  - platform: template
    name: "${devicename} - Switch"
    icon: mdi:power
    lambda: |-
      if (id(relay).state) {
        return true;
      } else {
        return false;
      }
    id: button_switch
    turn_on_action:
      - switch.turn_on: relay
    turn_off_action:
      - switch.turn_off: relay

Now the switch knows the state of the relay if something other than the switch changes it (like your boot sequence).

I understand. Thanks for explaining!
That does the trick! :slight_smile:
