@carloneb had the following scenario
He has a Drayton Wiser Basic Kit one thermostat in the kitchen but he doesnt have a Wiser TRV in the main room, he does however have a SONOFF Zibbee temperature sensor which is already integrated with Home Assistant. Can he get the heating to trigger the request for heat when the main room is cold? without purchasing a new TRV?
YES YES YES!
Definitions:
In Configuration.yaml, defined a new generic thermostat entity for the kitchen: “cucina”. This thermostat is commanding a switch (defined later) which is then triggering the Wiser’s commands. Also, the generic thermostat is linked to the Sonoff Temperature sensor (sensor.t_cucina_temperature).
climate:
- platform: generic_thermostat
name: cucina
heater: switch.switch_t_cucina

YES YES YES!
## How
Definitions:
In `Configuration.yaml`, defined a new generic thermostat entity for the kitchen: “cucina”. This thermostat is commanding a switch (defined later) which is then triggering the Wiser’s commands. Also, the generic thermostat is linked to the Sonoff Temperature sensor (sensor.t_cucina_temperature).
```yaml
climate:
- platform: generic_thermostat
name: cucina
heater: switch.switch_t_cucina
target_sensor: sensor.t_cucina_temperature
min_temp: 5
max_temp: 30
ac_mode: false
target_temp: 20
cold_tolerance: 0.3
hot_tolerance: 0
initial_hvac_mode: "heat"
The switch used by the above thermostat is as follows. It calls the wiser.boost_heating service when on (demanding heat) and sets the wiser to auto when triggered off (target T reached).
switch:
- platform: template
switches:
switch_t_cucina:
turn_on:
service: wiser.boost_heating
data:
entity_id: climate.wiser_soggiorno
time_period: 30
temperature: 21
temperature_delta: 1
turn_off:
service: climate.set_hvac_mode
data:
entity_id: climate.wiser_soggiorno
hvac_mode: "auto"Because the main temperature scheduling is owned by the wiser (it’s the master), I’ve created an automation that “copy” the scheduled temperature from the wiser to the Sonoff thermostat at any change.
- alias: Set target T cucina
description: Setta la T target di climate.cucina quando la T schedulata wiser cambia, tranne se in boost
condition:
condition: numeric_state
entity_id: climate.wiser_soggiorno
attribute: boost_remaining
below: 1
trigger:
- platform: state
entity_id: sensor.target_t
action:
- service: climate.set_temperature
data:
entity_id: climate.cucina
temperature: "{{ (states('sensor.target_t') | float) }}"In this way I can have both rooms heat following the scheduling set in the Wiser.
