I got this funky shower head as a christmas present last year. Turns out it doesn’t just display your water and energy usage, but also transmits the data via Bluetooth. Obviously this is something which is interesting to track over time, so I’ve decided to build a small integration for Home Assistant for it.
Protocol
Figuring out the protocol wasn’t too difficult since there’s already a bit of information on the protocol available. The Amphiro implements three types of BLE connections:
- passive connection: This is what my component uses, the shower head by default transmits the following vendor specific service UUID:
0000180a-0000-1000-8000-00805f9b34fb,7f402200-504f-4c41-5261-6d706869726fand00004132-504f-4c41-5261-6d706869726fevery time it is running. The payload has the same format as the status event in the next bullet - connected: this mode transmits a bit more data, but requires an active connection. There’s already an MQTT bridge available if you want to use this: Amphiro_Oras_bluetooth_shower_hub. I decided against this as active/connected connections are more complicated to implement and doesn’t add more value here.
- paired: The official app requires manual pairing with a pin displayed from the app. As the app also provides provides historic data I suspect in this mode one could also send queries to the device. From what I can tell, this is completely undocumented so far.
Home Assistant Component
This component supports reading sensor data from Amphiro Digital Hand Shower with the new bluetooth component released in Home Assistant 2022.8.
Let me know if you use this in the Home Assistant Forums, or open an issue on the GitHub repo should you run into any trouble:
I’ll also try to get this included in the Home Assistant Community Store (HACS) eventually1.
