ESPHome is amazing - there’s so much you can do without writing a single line of code.
I have built a few projects around the platform - a boiler monitor that tells me temperatures and state of zone valves, an energy monitoring system tracking electricity usage and solar export, and a hot tub mod that inhibits the heater to reduce grid import and maximize self consumption of solar. They have all been rock-solid stable.
Heh, typing YAML anywhere is squinty business. :-)
