HC3 Central heating – Underfloor



I just got HC3 and since I’m currently running my central heating with HC2 (Pellet furnace, Wood fireplace, Heat pump, Sun collectors all connected to a buffer tank +photovoltaics coming soon.
Output to 3 heating zones – pumps with mixing valves groups, each zone with 5 to 7 loops of underfloor heating – just ON/OFF now, DHW) for more than 10 years now. (since nothing decent exist for underfloor heating).


Since Lua of HC2 doesn’t run on HC3 I’ll need to make new ones.


Any suggestions what would be a right approach to tackle this on HC3 – Lua or QA?


Currently on HC2 mixing valves are driven by Roller shutters the rest by double relays and temperatures measured by DS1820 with Implants – old implants have problem that they get randomly stuck and will only continue if you disconnect power and connect it back. Room temperatures with Aotec aërQ.


I would also like to enhance functionality – better temperature control per room.


So my idea is to use few ESP32s -let say in each manifold to control thermal actuators on floor heating loops (let say8 )  with PWM (pulse being 10-20 seconds long), measure a forward water temperature and 8 return temperatures, get room temperatures with BLE sensors.
Probably just have separate ESP that would communicate with HC3 and other ESPs, deal with all pumps and mixing valves (3point) and getting temperatures of forward and return on mixing groups and in buffer tank. Control mixing valve for constant return temperature to feed buffer tank from pellets and wood furnace (min 60C). Solar works independently.
Heat pump: generally heats upper ¼ of storage tank (DHW directly) but since they planning to introduce 5 “tariffs” for electricity I would heat the whole storage tank when cheap(est) electricity is on – so maybe control schedules for electricity price with HC3.


I don’t want HC3 doing constant calculations and slow down other scripts so I would leave those to ESPs. For HC3 I would like to get (to ESPs) wanted room temperatures (from schedule) maybe outside temperature.
And receive back (from ESP) current room temperatures (14rooms), buffer tank temperatures, temp on pipes from different heating sources, just to be displayed by Fibaro. Not sure if it possible to send room temperatures to HC3 (in HC2 I couldn’t without being Zwave sensor)


Any suggestions?
Need more info?

ill recommend looking into quickapps insted of lua scenes :D
because you can add some visual looks and buttons to adjust things from the yubii/yubii home app 😄



check out @jgab tips and tricks :D 

and as jgab says down here "quickapps are long running scenes"

    I'll look at that.

    What I want to know is if i can set rooms temperature (in Fibaro) from QuickApp.

    I have mad myself a quickapp to add more Profiles to my termostat: 

    The "AwayE" E=eco :)
    And I have seen someone made quickapps for the climate panel too :) So it is possible :) 

    But climate panel schdule is also available in the quickapps (both yubii and yubii home) now 😄 (a few patches ago it was only control able with quickapps like this
