boiler VS esphome-mitsubishiheatpump

I tend to roll my own with rp-picos for no good reason other than they're easy. Wattmeter for a toy solar installation - broadcasts a UDP packet every few seconds, which I then record into a staging JSON log that gets ingested into DuckDB. Little pico-w wifi temperature sensor that feeds into the raspberry pi zero that controls my boiler.

github with some really crappy rust code: https://github.com/dave-andersen/boiler

The boiler control is the fun one but it's not entirely embedded stuff. Runs a little control loop that turns down the boiler modulation based upon the difference between target and current temperature. Improves operating efficiency by a fair bit and reduces temperature swings. Makes me wish residential HVAC systems were more sophisticated - these are things any good industrial control system can do.

Made an "ok to wake" light for my son -- added a controllable LED strip to his clock with a pico-w in it that changes from orange to multicolored at 6:30am as a non-intrusive "yes, you can come bug your parents" signal.)

Controlling Mitsubishi mini split heat pumps instead of paying hundreds for Mitsubishis solution: https://github.com/geoffdavis/esphome-mitsubishiheatpump

DIY Plug in: this Github Project describes a way to diy a plug in connection running on ESPhome for a few $ of parts, but I'm a bit of a novice and don't know how I would connect this to Homekit.

If you Home Assistant or ESPHome, this is the jam. https://github.com/geoffdavis/esphome-mitsubishiheatpump

Highly likely you're experiencing a watchdog error on an idle core. The only way to know for sure is to enable logger, which will be a challenge here. You can see an example here., but this is a widely reported and poorly understood issue.

If you can add homeassistant, you should look at https://github.com/geoffdavis/esphome-mitsubishiheatpump -- we're using it with 5 split units. It works great, is faster than infrared, and cheaper than the wired or wireless control options from Mitsubishi.

If your Mitsubishi uses IR for it's remote, this probably would work: https://github.com/geoffdavis/esphome-mitsubishiheatpump

Or, you can use a Broadlink IR blaster to clone the remote.

If your heat pump talks to MEL cloud (Mitsubishi's cloud thingy) then this should work: https://www.home-assistant.io/integrations/melcloud/

I have yet to buy a "smart" device that I haven't been able to control through HA. The Broadlink RF/IR bridges even makes anything with a remote automatable.

Seriously, If it wasn't for Home Assistant, the "smartness" of smart devices would be next to useless.
