Hi everyone,
I own a BYD Sealion 7 and there was no BYD app for Homey yet, so I built one. It connects to the BYD cloud (the same service the official BYD app uses) and brings your car into Homey and your Flows.
Install (test version): BYD Vehicle (unofficial) | Homey
The app has been submitted for certification, so it should appear in the App Store soon.
What it does
Status: battery %, range, charging state, time to full, battery power, locked, doors/trunk open, windows open, interior temperature, tire pressures, location, “at home”, car awake/asleep, odometer. A Refresh now button on the device tile.
Flow triggers: battery dropped below / rose above X %, charging started / stopped, cable plugged in / unplugged, car arrived home / left home, location changed.
Flow conditions: battery above/below X %, is charging, cable plugged in, car at home, car awake.
Flow actions: lock / unlock, start climate (temperature + duration), stop climate, flash lights, find car (horn + lights), close windows, refresh status, start / stop charging (experimental).
Before you start
- Use a second BYD account. BYD allows only one active login per account, so Homey would log you out of the BYD app on your phone. In the BYD app, share the car with a second account and use that one in Homey.
- Set a control PIN in the BYD app (Settings > Security) for that account. It is needed for lock/unlock, climate, lights and windows. Careful: several wrong PIN attempts block remote control for the rest of the day.
- Add the device: Devices > + > BYD Vehicle (unofficial), sign in, choose your country.
Tested cars
- BYD Sealion 7 (EU) – tested by me
Other models (Atto 3, Dolphin, Seal, Seal U, Han, Tang …) use the same BYD cloud and should work, but I can’t test them. Please let me know how it works with your car! Hybrids (DM-i) show the electric range only.
Good to know
- Every status update can wake the car, which uses some energy. The default interval is 10 minutes (5 minutes while charging), you can change it in the device settings.
- Start/stop charging is experimental and may not work in every region.
Reporting problems
If a value looks wrong, open the device settings, scroll down to Diagnostics and post the “Last raw charging data” line here, together with your car model and country. That helps me a lot.

This app builds on the great reverse-engineering work of pyBYD / hass-byd-vehicle by Joel Kåberg and ioBroker.byd by TA2k. Thank you!
