After Power Loss feature working
#1
Hi,

I successfully implemented a solution for having an "after power loss" feature on my rockpro64.
I use an esp8266 with a relay shield, connected to the rpi connector.  5V is provided through the rpi connector as soon as the 12v DC plug provides power
3.3v pin is connected to a GPIO of the esp8266. The pin is to 0v if the RockPro64 is off.
If the rockpro64 is off  the esp8266 detect that the 3.3v pin is down and it turn on the relay for 1s.

I use esphome to configure my esp8266.

Code:
switch:
  - platform: gpio
    id: rp64_switch
    name: "rp64_switch"
    pin: D1
   
binary_sensor:
  - platform: gpio
    id: rp64on
    filters:
    - delayed_off: 10s
    pin:
      number: D5
      mode:
        input: true
    on_state:
      then:
        - if:
            condition:
              binary_sensor.is_off: rp64on
            then:
            - switch.turn_on: rp64_switch
            - delay: 1s
            - switch.turn_off: rp64_switch

Hi!

If I understand what you wrote, you've made a system able to automatically restart your RockPro64 when recovering power after a power loss?! I'm looking for something to do this (I have now a UPS so short power losses would not even stop it and it would cleanly shutdown after longer power losses but I would like to be able to automatically restart if the power went down). Could you tell me more about what you've done?

Thanks!
Mathias

Hi Mathias,

Thank you for your comment ! I used a small development module that simulate a manually push of the power button when the power is restored.
For that it detects if the board is up through the 3.5v pin of the Rpi conector and if not, it shunt the button pins.
I'll upload all the stuff on my github account. Just let me a little time.

Best regards
