I want to control a bluetooth enabled automatic air freshner (Godrej Aer Smart Matic) from my Home Assistant.
Below is the link of the product;
The first problem is that my HA is running on my Pi 3 which is sitting in an isolated far off room; so using my Pi 3’s Bluetooth to connect to the Air Freshner is not possible with this scenario. I am not even sure if I would have been able to control the air freshner if it was located near my Pi 3. But still, I would like for a way to use an ESP32 running ESPHome or something like that to act as a bridge/gateway between my HA & the end bluetooth device. I know Xiaomi has a gateway that has bluetooth, but to the best of my knowledge it reads sensor data only; please correct me if I am wrong. Anyways I wanted to use an ESP32 because I was going to use its WiFi to connect to my network & then if possible use its Bluetooth to connect to Bluetooth enabled devices. Although I am not sure exactly if the end bluetooth device that pair with a smartphone’s bluetooth & get controlled via a app will work with HA through a Bluetooth Gateway/Bridge or not. But I still want to give it a try.
