You can make a thermostat with a raspberry pi, a few sensors, and a relay board. They're pretty simple devices.

Really, you don't even need a pi. An ESP8266 would be more than sufficient.

Source: I made my own thermostat from an esp8266, some sensors, and a relay board.

Not the person you asked, but i have a mitsubishi electric heatpump, which i have hooked up to homeassistant via an esphome library. It has a header on the controller board that you can connect to.

Normally the header is for their $200 controller and app, i spent $10 on the parts.

I think i better start mirroring the repo...

I'm running a Venstar Colortouch thermostat. They're not cheap, but they have a local API and there's a Homeassistant integration.

I have a Lennox multistage system with a heat pump, and furnace for when it gets too cold. The best way to run those (according to the installer) is at a low level all the time. So it doesn't benefit much from things like location tracking to turn the system up or down while we're out. Especially since I work from home.

What it does do is make graphs for tracking how it runs the heat pump and furnace each day.

Fork away!

Anna’s Archive is probably the best source for books. I use it all the time, actually, I even use it right now. It's also great for students who need textbooks. Fuck Pearson and those other scammers!

Yeah, even though the claim is 1000% horseshit, it’s not like some small time python dad has the means to defend against a giant multinational in court.

Laws are only for the common man.

The developer has not yet fully complied - the repo is still up, they have legal insurance and are in discussion with lawyers, and they have responded requesting clarification on the specifics of their alleged "violation".

In the mean time, I think many people have reached out to Haier to express their displeasure. On an unrelated note, the original menacing letter came from cybergovernance@haier-europe.com in case anyone was curious.

It sounds like someone out of their jurisdiction should host the repos and tell them to pound sand.

EDIT: sorry, I read it wrong, I thought the reply says the addon "doesn't" use the remote API.

I digged a bit on the code, and every command indeed go through the cloud. So even if you use this addon, Haire can still collect a fair bit of data about you, since there is no way to communicate locally and directly to the AC.

But the addon only sends the minimum amount of data to achieve functionality, so definitely not as much data as using Haire's app.

~~Can you link to where the documentation that specify they don't use API?~~

Because I am looking at pyhOn (dependency of hon, and also being taken down), it seems like when executing a command, they do contact the cloud. Specefically

url: str = f"{const.API_URL}/commands/v1/send"
    async with self._hon.post(url, json=data) as response:
        ...

https://github.com/Andre0512/pyhOn/blob/327d4a181484d49ccbef25e470cfc86d2c5d91fa/pyhon/connection/api.py#L215 . The call to API is later used to send command:

result = await self.api.send_command(
                self._appliance,
                self._name,
                params,
                ancillary_params,
                self._category_name,
            )

https://github.com/Andre0512/pyhOn/blob/327d4a181484d49ccbef25e470cfc86d2c5d91fa/pyhon/commands.py#L142

And the API_URL indeed points to a remote API:

API_URL = "https://api-iot.he.services"

https://github.com/Andre0512/pyhOn/blob/327d4a181484d49ccbef25e470cfc86d2c5d91fa/pyhon/const.py#L2

Well then I guess it is pretty obvious
