Comfort features¶
Beyond the core control loop, a handful of features shape where the band sits: presets, a manual band, per-area offsets, and two opt-in features that adapt the band to the weather.
Presets and their edges¶
Each preset (Home / Away / Sleep) is a pair of setpoints — a heat edge and a cool edge. Selecting a preset on the thermostat applies its two edges; editing the active preset's number moves the live setpoint at once. Heating runs below the heat setpoint, cooling above the cool setpoint, nothing between. Each edge is editable within 7–35 °C.
| Preset | Heat setpoint | Cool setpoint |
|---|---|---|
| Away | 16.0 °C | 30.0 °C |
| Home (default) | 20.5 °C | 24.5 °C |
| Sleep | 19.5 °C | 23.5 °C |
The preset edges live as number entities on the hub device (e.g. Preset Home
heat setpoint), so automations can edit them too.
Don't need them all? The Presets multi-select in the integration's Configure dialog narrows the offering: deselected presets disappear from the thermostat and their setpoint numbers aren't created (existing ones are cleaned up). The manual band is always available. If the active preset is deselected, the thermostat falls back to Home — or to manual when Home isn't selected either.
Boost¶
Boost (HA's standard boost preset) is a temporary override, not a band of its own: select it and the current preset's band gets its demanded edge pushed by Boost offset (default 2 °C) for Boost duration (default 30 min), then the previous preset comes back automatically. The direction is fixed when you select it:
- heat-only setup → heat boost (heat edge up); cool-only → cool boost (cool edge down);
- heat/cool setup → whichever side of the band midpoint the home currently sits on: a cold home gets a heat boost, a hot one a cool boost.
The big band error makes the MPC valves open wide and the AC drive hard — but it's still just a band, so every guard (window-open, frost, outdoor gating, per-area offsets) keeps working, and the adaptive cooling-comfort shift is suspended so it can't water the boost down. Selecting any preset or touching the setpoints ends the boost early; re-selecting Boost restarts the clock; a restart mid-boost resumes it with the original deadline. Deselecting the boost preset in the options while a boost is running ends it on the next reload, landing on the preset it would have reverted to.
The manual band¶
You don't have to go through a preset: moving the setpoints directly on the
climate.climate_orchestrator entity adjusts the live band. With both TRVs and
an AC configured you get two setpoints (the band); with only one device kind, a
single setpoint (heat-only or cool-only) — see
How it controls.
Per-area band offsets¶
One band still doesn't suit every room equally, so each managed area gets a
<area> band offset number (default 0 °C, range −5 to 5):
- a positive value shifts that area's whole band up — the room heats sooner and stops cooling later, so it runs warmer;
- a negative value runs it cooler.
The offset biases only that area's own reading, never the home average, so nudging the bathroom warmer doesn't drag the rest of the house with it.
Relaxing the cooling when it's hot out (Adaptive cooling comfort)¶
With Adaptive cooling comfort on (optional, off by default), the cool setpoint, and only the cool setpoint, relaxes upward once it's hotter outside than you'd cool for anyway. It tracks a slow running mean of the outdoor temperature:
onset = cool setpoint + bias
excess = max(0, running-mean-outdoor − onset)
cool shift = max shift × (1 − exp(−excess / response))
The cool edge stays at your preset until the running-mean outdoor passes the onset, then eases upward by a smooth, saturating amount — gently at first, ever more slowly, approaching but never reaching the max shift cap. The heat setpoint is never touched. Three numbers shape the curve: max shift (the cap), onset bias (how much hotter than the cool setpoint it must be before relaxing starts), and response (how gently it ramps).
With a Home preset of 20.5/24.5 and the defaults (onset 25.5°):
| Running-mean outdoor | Cool setpoint |
|---|---|
| ≤ 22° | 24.5° (no shift) |
| 28° | ~25.5° |
| 33° | ~26.1° |
| 45° | ~26.5° |
The adjusted cool edge is always computed (the Adaptive cool setpoint sensor previews it even when the toggle is off) but only applied when the toggle is on, which requires an outdoor sensor.
Tip
Watch the Adaptive cool setpoint sensor through a hot week before enabling the toggle — it shows exactly what the feature would do, with no effect on control.
Pre-heating from the forecast (Forecast preconditioning)¶
With Forecast preconditioning on (optional, off by default, MPC calibration mode only), a radiator can start warming a room before a cold spell arrives instead of only reacting once the room has already cooled. The MPC valve optimiser normally plans against the current outdoor temperature held flat; with this on, it instead plans against the configured weather entity's hourly forecast, interpolated onto the control step over the Preconditioning look-ahead — a tunable number (0.5–8 h, default 2 h). If the forecast shows it getting colder, the optimiser opens the valve more now to stay ahead of the loss.
To keep comfort safe it only ever raises the valve: the commanded opening is the larger of the normal (react-to-now) result and the forecast-aware result, so the forecast can pre-heat but never under-heat the present. The forecast is refreshed about every 15 minutes; if the weather entity stops responding, a cached forecast older than ~3 hours is ignored rather than trusted (the optimiser falls back to planning against the current outdoor temperature). Needs a weather entity that provides an hourly forecast; without one, a repair notice points you to add it (or turn the feature off).
