@TakieYC for sure ViCare is far behind those when it comes to heating systems with radiators.   However, after quick check: Nest, Tado, Netatmo, Bosch Easycontrol does not support controlling the underfloor heating circuits. They can only communicate with a boiler using OpenTherm (or similar) protocol.   Honeywell Evohome can do that with the following controller: https://heatingcontrols.honeywellhome.com/products/Underfloor-Heating/HCC80/ ... but their website makes me think they are as modern company as Viessmann.    ...   I think in central/eastern Europe underfloor heating is the most popular choice these days. Having closed underfloor heating circuits I have no need to optimise the boiler work, because it uses less than 1kwh energy (less than 0.03 EUR) a day to maintain the temperature in boiler controlled circuits. However, low temperature underfloor heating has big inertia and I am right now thinking it can be a reason why the big players do not support those heating systems... so I still see ViCare and its limited capabilities could fit my needs.        ...

@TakieYC I was checking your experiences about the Smart Climate and that is why I am asking here about the APIs. In Open systems (or ones that expose some kind of API) you can implement/fix many things on your own. What commercial system would you pick to replace the Smart Climate?   In general in my current setup (only floor heating) everything works pretty OK. I use the typical (not smart) wired thermostats in every room that closes the valve (dedicated for a given room) in the floor heating circuit if needed (thermostat implements some algorithm, probably PWM).   To make it smart I was thinking about adding zigbee temperature sensor in every room and control the valves based on my logic  - and then realised the Smart Climate uses exactly such technology with a gateway that I already have (vitoconnect).   So I am double checking if using Smart Climate would be a good solution for me ...      ...

Smart Home systems become really smart only when they can be integrated with other components of Smart Home. So I am using PyViCare API client through ha integration to read the state of the heating system and to control it when needed.    When upgrading from circuit control to per-room control I can image many scenarios where public API is needed: * check the charts of (historic) ViCare sensor room temperature to adjust manually your heating system (i.e. adjust temperature curve on the boiler/circuit or the maximum flow on your floor heating circuit) * control the humidifier(s) based on the humidity value from the ViCare sensor * try to adjust the temperature based on the humidity (sometimes it could make sense to lower temperature to increase humidity and your comfort will be the same) * switch to reduced temperature when you are not present at home (presence sensors or geolocation and the distance from home)  * disable the heating in the room if the window is open  * switch to reduced temperature for the room if the expected energy from the sun will be enough for a given day (based on sun radiation sensor or weather forecast)    Btw. not asking about it here, but publishing all the data to local MQTT broker could be a game-changer for you in longer term.  ...

So, accuracy for sure is not the best from that sensor. It looks like its precision is +/- 1 degree Celsius.    However, I see the value is much more frequently updated in my case. See the attached image.  ... Mehr anzeigen
