Minimum opening of the valve

[patti9000]

Is there a possibility for configuring an minimum opening for each valve?
Why? Well, in my case im living in a flat an we don't have to heat that much. The result of that, is that our floors are cold most of the time. The Homematic IP FALMOT (in combination with RaspberryMatic) lacks this feature and this is why I'm looking for different options.
Thanks

Hi,

It's not a buildin function, but you have full access to the code and can make everything you want.

Perhaps, the better way to go is to modify

floor-heating-controller/heating_channel_linear.yaml

Line 143 in 5149efd

if (target_position <0) { target_position = 0;}

and adding :

if (target_position <id(min_valve_pos).state) { target_position = id(min_valve_pos).state;}

with a value you set in inputs.yaml

number:
   
  - platform: template
    name: "min valve position"
    optimistic: true
    min_value: 0
    max_value: 100
    step: 1
    restore_value: true
    initial_value: 5
    id: min_valve_pos

You have to understand in low temperature floor heating, if the foor is at 28°, you are heating at the max power and the valves are full open.
This will result in the room getting hot.

That's why nobody make that kind of implementation.

If you have already a controller, you can play with the target temperature to find you area of confort before changing the system.
