# climate set

This block is part of the [`globals`](https://docs.rual.nl/block-types/globals) group and was last modified in core [`v15.0.0`](https://docs.rual.nl/core-versions/150000).

Sets an air conditioner or thermostat: on/off, mode, target temperature, fan speed.

- flow `v15.0.0` `flow`

- device `v15.0.0` `value` Device id, native address, or exact device name. Leave empty to use the device picked on the block.

- mode `v15.0.0` `value` Leave empty to keep the current mode. • Suggestions: `off` `auto` `cool` `heat` `dry` `fan`

- target °C `v15.0.0` `number` Target temperature in Celsius.

- fan `v15.0.0` `value` Leave empty to keep the current fan speed. • Suggestions: `auto` `silent` `low` `medium` `high` `turbo`

- flow `v15.0.0` `flow`

- ok `v15.0.0` `condition` True when the command reached the device.

- device `v15.0.0` `object` The device the command was sent to.

- error `v15.0.0` `value` Empty on success. HOMEASSIST_DEVICE_NOT_FOUND, HOMEASSIST_DEVICE_NOT_ADOPTED, HOMEASSIST_CAPABILITY_UNSUPPORTED or HOMEASSIST_NOT_AVAILABLE.

Commands a climate device : a Daikin air conditioner over its local LAN API, a Zigbee/Z-Wave/Matter thermostat over the radio. Mode is one of off, auto, cool, heat, dry, fan. Setting a mode other than off implies switching the unit ON. Target temperature is degrees Celsius. Fan is auto, silent, low, medium, high or turbo; devices without that many speeds get the nearest they have.

A typical wiring for [climate set](https://docs.rual.nl/block-types/globals/homeassist_climate_set): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%2520ui/state_debug).
