Quick start
Heat pump and air conditioning
A heat pump measures the temperature at the indoor unit, often far from the reality of the room. Versatile Thermostat corrects its setpoint with a real sensor and stops it when it's no longer needed.
Versatile Thermostat's strengths
Self-regulation
Versatile Thermostat adjusts the setpoint sent to the heat pump so the room sensor reaches the target temperature. Four levels, from light to expert.
Automatic stop and restart
When the room is at temperature, the heat pump is stopped (or switched to fan or dehumidification) then restarted at the right time: less consumption and noise.
Heating and cooling
The same thermostat heats in winter and cools in summer, with presets dedicated to cooling. Auto-Fan adapts the fan speed.
Open windows
The heat pump stops or switches to fan mode when a window opens.
Presence
Away setpoints apply automatically, for both heating and cooling.
Power shedding and central mode
The heat pump takes part in power shedding. Central mode forces the whole home to heating only or cooling only.
Tutorial: a living room with a Mitsubishi heat pump
Example: a living room cooled by a Mitsubishi air-to-air heat pump integrated via MELCloud, with a temperature sensor placed far from the indoor unit.
Integrate the heat pump
Add your heat pump's integration (MELCloud, Daikin, SmartIR...) in Home Assistant and check that its climate entity responds.
Install Versatile Thermostat
Install the integration from HACS, then restart Home Assistant.
Create the thermostat
Add the Versatile Thermostat integration, choose “Thermostat over a climate”, name it “Living room” and select the temperature sensor and the outdoor sensor.
Add the heat pump
In “Underlyings”, select the heat pump's climate entity and tick cooling mode if it is reversible.
Enable self-regulation
In “Self-regulation”, choose the light level. It corrects the setpoint sent to the heat pump by up to 1.5 °C.
Enable automatic stop and restart
Choose the responsiveness (slow for a living room, fast for a small room) and the stop action: turn off, fan only or dehumidification.
Set the presets
Define the heating temperatures (for example 18 / 20 / 21 °C) and the cooling temperatures (for example 26 / 25 / 24 °C).
Start with light self-regulation and raise the level only if the room doesn't reach its setpoint. Avoid aggressive settings with heat pumps that cut their compressor too often.
