Hi!

Could you please explain how scenes are triggered? And I will be glad for any advices!

I am trying to setup electric-heating with vera lite for a small village house.

I have vera lite, 7 (each for a room) multisensors (6 fibaro and one aeon) and 9 plugs (2 rooms has 2 plugs) with electric heaters plugged in.

I have 2 scenarios:

  1.  Away. Nobody at home, inside temperature should be above 0 (preferably 3-5 degrees C). Purpose: to keep water-pipes safe from freeze.

  2.  Home. Some rooms are occupied, temperature should be different in different rooms (3-5 in unoccupied, for warmer-better people 25 C, for me 22 C).

For ?Away? I created for each room a set of scenes:

1.a) when temperature goes below 5 degrees, turn plug on

1.b) when temperature goes above 7, turn plug off if mode is away

Why scene (1.b) is not triggered when I switch to ?away? mode (from home) and temperature is already above 15 degrees? When will it trigger? When fibaro temp sensor will report new temperature?

I have not altered fibaro multisensors parameters. Which should I change? wake-up intervals or period of temperature measurements or something else?

For Home I created for each room own set of scenes:

2.a) when temperature goes below 23 degrees, turn plug on if mode is home and if virtual switch* for a room is on

2.b) when temperature goes above 25, turn plug off

*For each room I added virtual switch (thanks for plugin!) and added lua if statement for a scene

My scenario for Home doesn?t work as I expect either (probably due to lag of temperature updates?): it turns on heating when it cold already and switches it off then it too warm…

Moreover it?s not convenient to change temperature for each room: Only I (not other family members) should manually edit scenes? there is no virtual device to set temperature in it (alike virtual switch) is it?

Could you please advise how to make this setup more convenient to use? Even for people without smartphone?

One idea might be to use the Virtual Smart Thermostat plugin, one Virtual thermostat per room.
The multi sensors provide the temperature input.
2 scenes then per room. One scene for when the sensor is tripped that activates the ‘Comfort’ mode on the thermostat. When the sensor is not tripped, then back to ‘Eco’ mode. Set the set points how you want them.

Moving up the complexity, depending how quick the rooms take to heat up: a scene that increases the ‘eco’ mode set points if there is movement in any room in the house. If there’s no one at home, then reduce the set point.

Thank you for reply!
Before buying all the hardware I found this plugin and planed to use it. But as far as I understand now this plugin can’t create more than 1 thermostat? Will try again in the evening, hope i made a mistake!

Should I alter wake up time of multisensor?

If you go into the apps menu and click on the smart virtual thermostat, you can create more devices.

I’ve played around with timers and count downs, but I certainly find it easier now to have the sensor tripped for a longer period. Eg, my kitchen sensor is on a 10 minute timeout so the heating (and lighting) is on comfort mode for 10 mins after activity before clicking down to Eco.
