Connection issues

If the app can't reach your unit, check that your phone is on the same Wi-Fi network as the unit and that the address in Settings still matches the unit's address on your router. Units on DHCP can change address after a power cycle — set a static or reserved IP on your router to avoid this. A unit reached through its manufacturer's cloud needs no address, but it does need the internet at both ends.
Step by step
- Confirm the unit is powered on
- Check your phone is on the same Wi-Fi network as the unit
- Verify the IP address in Settings still matches the unit
- Restart the unit's Wi-Fi module by power-cycling the unit
