In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`switch`	Switch or outlet
`sensor`	Sensor (temperature, humidity, air quality…)
`select`	Mode picker (as switches)

What people report

Grow-room controller that works with generic HA sensors and Plantalytix FridgeGrow devices; a Tasmota ESP32 with SHT3X and BH1750 setup worked once PPFD/DLI calculation was added.

Tasmota ESP32 with SHT3X and BH1750 sensors	Works Local	Temp/humidity visible; light sensor drives PPFD/DLI after fix Saved copy Hello Following scenario: I use an ESP32 (Tasmota) for controling one Tent. SEnsors: SHT3X,(Temp, Humidity, Dew Point, BH1750 For Light intensity. The SHT3X values are seen from OGB in the Gui. The BH1750 is also seen as Light Intensity Sensor (But the Entity Name is not Like in the Device Name Doku. The Doku (WIKI Device Names)says the Entity NAme should be "...illuminace"), when using the Device Entity Name OBG says "no Light Intensity Sensors), if I rename the Entity Name in Tasmota to sensor.lightintensity and restart HA the OBG Gui shows the Sensor an a Value in Lux but no DLI and PPFd … Excerpt saved from GitHub on 2026-10-23.
