I understand, and I could make it clear in the description that AC is capped at 18 degres C minimum (65F), so people who like it very cold could skip my airbnb. Some AC can go ridiculously low ( http://news.bbc.co.uk/2/hi/uk_news/england/3144803.stm ). I do not want to change the temperature remotely, I just want to not have the AC used to extremely cold temperature. I am fine to advertise it to weed of people who li…
I should have bothered to do the conversion... when I read your post I was immediately reminded of the recent laws in Italy that capped AC in public spaces to a minimum of 25C... 18C is awfully cold for a residence! Most programmable thermostats in the US do have built-in limits for device protection. I've never met anyone who sets AC in a home to lower than 68F and that is an absolute extreme. Most central AC system…
> 18C is awfully cold for a residence
Yeah, why set the upper limit to 22 and not like 24-25? It will save you even more power for those that don't sit in your airbnb in a 3 piece business suit...

If you have same schedule every week, don't go on vacation, your kids don't have breaks, don't have seasons, then 'set and forget' dumb thermostat will work for you without any problems. For the rest of us we need some 'smartness' in our thermostats.
You shouldn't need to change the temperature regardless of those things. My house remains at 68-72F basically all the time. Thermal cycling accelerates aging of materials.
Isn't the thermal cycling greater outdoor than indoor because of the differences in the outdoor temperature between day and night? So most ordinary materials indoors should be fine with a delta of even 10 Kelvins/10 Celsius/18 F.
All of the material thermal failures I can think of come from localized and more extreme sources: electronics, lightbulbs, washing/drying clothes, washing dishes in a dishwasher. Water below freezing point too, but that's because the temperature fell below a threshold. None of these are from heating or cooling rooms directly with HVAC.

#44For anyone wondering why he would ever do this, it seems to be a type of hidden mini-split system used in euro-style shoebox flats, with a super-proprietary thermostat. Wi-Fi capability is an option at additional cost, but was not purchased. In the USA, wired thermostats tend to use standardized 24V wiring schemes, or 208V/240V for mains voltage heaters (electric heat, common on the west coast, especially in shitty a…
FYI this kind of thermostat is actually better. American style thermostat put your HVAC system in either on or off state (basically PWM), whereas this kind of communicating thermostat can tell the system what the temperature is, so they adjust power accordingly. I do wish they have standardized protocol though.
In some countries there are devices supporting the OpenTherm protocol: https://en.wikipedia.org/wiki/OpenTherm https://www.opentherm.eu/

#45I did similar with our coffee machine a year ago - I was bored of getting home from the school run to a cold pot of coffee because the machine automatically turns off the hot plate after 30 minutes, and it seems there is no such thing as a WiFi connected drip coffee machine. Kettles, yes, coffee machines, no. Dead simple. Cracked it open, chucked an ESP32 in there connected to the soft power button, and to the “machi…
> Now, she opens her bedroom door, I get “kid is awake” alert on my phone, and the machine brews the coffee.
Out of all of the smart home threads and articles I've read over the years this is the only sentence that made me wish I had it. It's genius

#49Mitsubishi AC units that support M-NET have a CN105 port. IIRC, my specific model uses a JST PA 5-pin connector rather than a JST PH 5-pin.
As a small hack, I used the Python scripting interface in Home Assistant to replicate this [1] feature from Panasonic HVAC that gradually raises the cooling set point towards the morning. It is quite comfortable during the summer.

#50I'm hoping to get a mini-split system installed soon and thought I might as well look for something with HA integration. It's not easy. Some manufacturers like Samsung actually want to charge you monthly for cloud integration! Completely out of the question obviously. I came across this, and Mitsubishi is supposed to be good anyway. I would prefer something that's actually supported but I can't seem to find any other…
I have a Daikin system. I use Faikout(ESP32 that controls the heads via the debug port) to control my units from home assistant. Works great!
Their official service needs an app and cloud access to control it. And I absolutely refuse to do that.
