I’m thrilled to share my recent success in integrating my Govee H714E humidifiers into Home Assistant! After some trial and error, I managed to reverse-engineer their BLE protocol and set everything up seamlessly. Here’s how I did it:
-
Understanding the Protocol - The devices send out manufacturer data payloads with mfg. id 8802. The fifth byte indicates whether the humidifier is on (1) or off (0). By analyzing the request-response mechanism, I figured out the exact commands needed to toggle the humidifier.
-
Setting Up Home Assistant - I used the BLE integration in Home Assistant to connect the devices. It was crucial to ensure that the advertising data was correctly parsed and that the state was updated in real-time.
-
Automation Magic - Now, I’ve set up automations so that the humidifiers turn on when the room humidity drops below a certain threshold. It’s been running smoothly for a few days now, and I couldn’t be happier!
If anyone else is looking to integrate their Govee H714E humidifiers, I’d be happy to share more details or help troubleshoot. It’s a fantastic way to enhance your smart home setup without relying on cloud services!
Cheers to the Home Assistant community for all the resources and support!
