There's a few things it's missing from being close to a dream thermostat for me. First thing is that it's relay and not dimming.
It's a good start, and interesting how they have both a heating and cooling component - however it looks like it's just an on/off unit, and not a dimming unit. (Possibly one of the reason's it's cheaper?). I can understand on/off being for refrigeration (if you were doing this you definitely wouldn't want that to be dimming - but for heating dimming would be nice).
Also - with anything that is IoT based - make sure you have all your other devices on the network locked down. These cheaper IoT devices, whether they be wifi lightbulbs, etc often are using chipsets that can potentially be hacked and then used to get into the rest of your network. They're made to a price, not to a level of security and often share very common chipsets so if a exploit is found it can be across multiple devices.
Of course, if you have the rest of the devices on your network locked down, or the IoT devices are in a DMZ section, or running via VPN and not using port forwarding, etc then it reduces the risk significantly - it's just a matter of taking reasonable precautions and expecting that it's possible it may be hacked down the track.
I haven't found my dream thermostat. My ideal thermostat would be something similar to the Microclimate Evo Pro, but with longer logs (ie 30 days or more) that are downloadable into CSV files and with the option to be remotely controlled via network. (Just because I'm cautious about IoT doesn't mean I don't think it shouldn't be an option
).
For many years I've dreamed of being able to check the temperatures online.
You still can.... and without the risk of trusting your animals to a $55 device.
If monitoring alone is worth $55 to have this feature, why not buy the InkBird and use it solely for monitoring.
Let your Microclimate or whatever thermostat you currently use continue to control the heating and have this as a secondary unit for remote monitoring only.
