Reboot if ESP loses connection -

[EasilyBoredEngineer]

Hi all,

Just to let you know a way to reboot your esp if you have a crappy wifi AP and find that your esp periodically loses connection.

At first I tried using the 'restart' platform set as a switch with an 'interval' automation set to every 15 minutes, but that put the esp in a reboot loop as interval is executed automatically at boot.

The solution is to use the time component - below is the relevant code block.

It basically tests every 2 minutes to see if your esp has a connection to home assistant, and if it doesn't it reboots. Seems to have made my system more solid - but, as I said, this isn't to address a problem with syssi's project (It's great!!) - it's just to address an issue I've found with my particular cheap wifi AP.

switch:
  - platform: jk_bms_ble
    charging:
      name: "${name} charging"
    discharging:
      name: "${name} discharging"
    balancer:
      name: "${name} balancer"
  - platform: restart
    name: "Esp Restart"
    id: esp_reset
    restore_mode: ALWAYS_OFF 
  - platform: ble_client
    ble_client_id: client0
    name: "${name} enable bluetooth connection"

#check connectivity and reboot

time:
  - platform: homeassistant
    on_time:
      - cron: '* /2 * * * *'
        then:
          if:
            condition:
              api.connected
            then:
            #nothing
            else:
              - switch.toggle: esp_reset

PS If anyone can recommend an action other than a restart that might work to reestablish comms in such a circumstance, please do suggest :)

The reboot_timeout of the native api component does pretty the same. Please have a look to probably simplify your setup again.

Thanks @syssi - reboot timeout for some reason doesn't seem to detect 'my' type of wifi disconnect - my reboot timeout is set at 15 minutes and I've had my system sitting there for 6 or 7 hours disconnected from the api with nary a reboot in sight... I don't know what the issue is - I never have such timeouts with my mikrotik and unifi AP's but with my din mount PROTOSS PW21 it's a real issue - but then some of my ESP32 boards won't even connect in the first place with that AP so it's obviously got some issues :)

PS here's a photo of a site I'm testing your code at. It's at Uluru / Ayers Rock.

Wow! What's the purpose of this setup/experiment? It looks like a ham radio site.

Yep you're close - it's a radio / microwave repeater site. Because the area is culturally significant I use very short height facilities that can be removed easily after we've got no need for it anymore - technology is far more transient than landscape.
