Integrating a dumb coffee maker with Home Assistant via ESPHome

My beloved coffee maker of 10 years has finally died 😢. Parts are no longer available from either the manufacturer or the second-hand market.

Taking advantage of a (slight) holiday sale discount, I pulled the trigger on a coffee maker that’s designed to be repairable forever. The perpetual serviceability is a side effect of an ultra-simple design; this coffee maker has zero intelligent features which means there’s next to no remote control or customizability.

Teardown and Home Assistant integration with two generic Chinese 'smart' power strips.

I love the Sonoff-S31 smart plugs. They’re cheap, well made and - most importantly - trivial to flash with ESPHome and integrate into Home Assistant. They do have one obvious draw back, though; optimized for a “traditional” US style outlet. When you try to deploy them to a power strip, you end up loosing about 50% of the outlets on the strip!

This is how you loose about 50% of the outlets on your power strip.
