It has 1.6k installs sharing analytics, works locally and was last updated October 25, 2026. Climate Group Helper combines several thermostats, TRVs, ACs and heaters into one virtual climate controller. It adds a group climate entity along with a main switch, a group offset number, and temperature, humidity and configuration sensors. Member readings can be summarized as mean, median, minimum or maximum, or replaced by external sensors whose values can be written back to TRV calibration targets. Sync modes (Mirror, Lock, Master or Adopt Only) react to manual changes on members, and a master entity can act as the leader. It also covers window detection, presence offsets, schedules and calendars, custom presets, and a timed boost that reverts afterwards. A dashboard card is included, and setup runs in the UI with local control. Automatic summary of the README and code of bjrnptrsn/climate\_group\_helper.

No vendor cloud in between. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### Climate Group Helper - **Group Name**: A friendly name for your group (e.g. 'Living Room' or 'Whole House'). - **Climate Devices**: Select the climate devices (thermostats, ACs) to include in this group. ### After setup - **Advanced Features** - **Expand all sections by default** - **Climate Devices**: Add or remove devices. Removing devices stops them from being controlled by the group. - **Master Entity**: Designate one member as the Master Entity (Leader). It is used for Master/Lock synchronization and centralized target display. - **HVAC Mode Strategy**: Strategy for calculating the group's state from its members (e.g. if one is 'heat' and another is 'off'). - **Feature Strategy**: Determines which features (e.g. preset modes, fan modes) are available on the group when members have different capabilities. - **Out-of-Bounds Action**: What to do with members that cannot reach the target temperature. Only applies when Feature Strategy is set to Union. - **Unsupported HVAC Mode Action**: What to do with members that technically do not support the group's target HVAC mode (e.g. AC when heating). Only applies when Feature Strategy is set to Union. - **Target Temperature**: How the group summarizes the target setpoints of its members. - **Use Master Target Temperature**: Display the master entity's setpoint as the group's target temperature instead of the member average. Falls back to averaging if the master is unavailable. Affects only how the group state is displayed — it does not control or synchronize members (use Sync Mode: Master/Lock for that). - **Target Temperature Precision**: Only applies to values sent to devices, not to current/displayed values. - **Current Temperature**: How the group summarizes sensor readings from its members. - **Minimum Temperature when Off**: Sends the device's minimum temperature (e.g. 5°C) when turning the group off. This ensures valves are fully closed for frost protection. - **External Temperature Sensors**: Use external sensors instead of member readings. These become the sole source of truth for the group's temperature. - **Write External Temp to Entities**: Write the external sensor value to number entities (e.g. TRV calibration offsets). Useful for keeping thermostats aware of actual room temperature. Texts from the code of [bjrnptrsn/climate\_group\_helper](https://github.com/bjrnptrsn/climate_group_helper). ## Entities - **Climate**: Climate Group - **Numbers**: Group Offset - **Sensors**: Temperature, Humidity, Configuration - **Switches**: Main Switch ## Actions - **Set Schedule Entity**: Switch the active schedule or calendar entity at runtime. If omitted or set to null, the group reverts to its configured default and re-applies the current slot. Fields: Schedule / Calendar Entity - **Set Schedule Bypass Entity**: Switch the active bypass entity at runtime (e.g. to swap between different vacation calendars). Set to null to restore the configured default. Fields: Bypass Entity - **Set Schedule Fallback Payload**: Sets or clears a fallback payload applied when the main schedule is off. Overrides the configured fallback payload. Fields: Fallback Payload - **Set Group Preset**: Sets, changes, or removes the group's runtime presets. They add to the config presets from the group settings and take precedence over one of the same name. Fields: Payload - **Boost**: Temporarily set the group to a target temperature for a fixed duration. When the timer expires, the group restores automatically to the active schedule slot (if configured) or its previous target state. Fields: HVAC Mode, Temperature, Temperature Offset, Duration (minutes) - **Apply Configuration**: Apply a portable JSON configuration to a group. This is useful for copying logic settings between groups or restoring a backup. Identity keys (name) are protected. Afterwards, open the group's settings and save once — the settings dialog additionally checks that the applied combination makes sense. Fields: Settings (JSON), Include Member List, Include Entity Selectors - **Reset**: Resets temporary overrides and runtime state (boost, offset, schedule, bypass, fallback, presets) back to configured defaults. Select at least one option, or use "Everything". Fields: Everything, Boost, Temperature Offset, Schedule Entity, Bypass Entity, Fallback Payload, Group Presets ## Troubleshooting - **Diagnostics**: Downloads a diagnostics file to attach to a bug report. ## From the README > The advanced logic layer for your Home Assistant climate devices. > > Sync, automate, and fix your thermostats — set up entirely in the UI.
