Hi there,
I am using Fritz! dect 301 radiator thermostats (along with fritz! dect 440 temperature sensors), but I can’t get a ‘readout’ on when they are actually heating, only when heat mode is one. I like to know when they are heating, e.g. open so hot water can flow through, so I can send a command to the boiler to run. I have this method working for my underfloor heating, but not for the radiators.
Now I got the following solution:
- I create an extra thermostat, e.g. bathroom-2 (“badkamer” in Dutch)
- I use the sensor from the corresponding 440 temperature sensor (in fritz! box assigned to the 301 radiator thermostat).
- I now know when the thermostat-2 is heating, so I can control the boiler with an input_boolean helper.
- I want to use the the target temperature of the thermostat-2 as the target temperature for the radiator thermostat. Here I can’t get it to work, see below:
What works:
- platform: generic_thermostat
name: Badkamer_thermostaat-2
unique_id: "Badkamer_thermostaat-2"
min_temp: 12
max_temp: 35
target_temp: 16
hot_tolerance: 0.5
target_temp_step: 0.5
heater: input_boolean.thermostat_status_badkamer-2
target_sensor: sensor.current_temp_badkamer-2
- platform: template
sensors:
current_temp_badkamer:
friendly_name: "Current T badkamer"
unit_of_measurement: '°C'
value_template: "{{ state_attr('climate.badkamer', 'current_temperature') }}"
- platform: template
sensors:
target_temp_badkamer:
friendly_name: "Target T badkamer"
unit_of_measurement: '°C'
value_template: "{{ state_attr('climate.badkamer', 'temperature') }}"
- platform: template
sensors:
target_temp_badkamer_2:
friendly_name: "Target T badkamer 2"
unit_of_measurement: '°C'
value_template: "{{ state_attr('climate.badkamer_thermostaat-2', 'temperature') }}"
What doesn’t work:
An automation to copy the target temperature from badkamer-2 to badkamer, I wanted it like this:
alias: Target_badkamer
description: Van target temp badkamer 2 naar target temp badkamer
trigger:
- platform: state
entity_id:
- sensor.target_temp_badkamer_2
condition: []
action:
- service: climate.set_temperature
data:
temperature: sensor.target_temp_badkamer_2
target:
entity_id:
- climate.badkamer
mode: single
However, I can’t get this to work, when I change the target badkamer-2 it doesn’t change target badkamer. If for example I use this:
alias: Target_badkamer
description: Van target temp badkamer 2 naar target temp badkamer
trigger:
- platform: state
entity_id:
- sensor.target_temp_badkamer_2
condition: []
action:
- service: climate.set_temperature
data:
temperature: 10
target:
entity_id:
- climate.badkamer
mode: single
Then it does work, e.g. changing target badkamer-2 changes target badkamer to 10 degrees.
So the automation itself works, but using a sensor / value as new temperature just doesn’t.
Any tips on how I can get this to work?
