Making my Microwave Smart(ish)

This is probably my favourite automation to date!

The time on my microwave is never correct. For various reasons it is fairly regularly power cycled and in doing so the time is reset to 1am. The controls to set the time are horrendous and so I just don’t bother.

I was walking past it yesterday and thought “I wish we just had a power cut at 1am every day…wait a minute, I can do that!”.

We’d just taken down the Christmas tree so I handily had a spare RF plug avaiable. A quick automation later…

- alias: microwave_reset
  initial_state: true
  trigger:
    platform: time
    at: '00:59:45'
  action:
    - service: switch.turn_off
      entity_id: switch.microwave
    - delay:
        seconds: 15
    - service: switch.turn_on
      entity_id: switch.microwave

And now every night, 15 seconds before 1am the microwave is turned off, then 15 seconds later it’s turned back on again. Now the time on the microwave is basically synced with a time server every night and even adjusts for daylight savings :grinning:.

nice, what kind of physical switch you’re using for your microwave since many of them are higher than 1500W

Good call @firestrife, I’d like to say I’d checked this but hadn’t :grimacing:.

It’s all good though, the switch (a 433mhz RF switch) is 10A rated which nicely covers the max power of my microwave.
