Did anyone manage to connect Shelly BLU H&T with encryption switched on ? When adding the device to HA, it requires passkey. If I enter encryption key visible in Shelly BLE Debug app, it’s not accepted. Any idea where to get passkey ?
hi @Jar21 just came across your posting here when facing the same issue.
Looks like I found a solution:
when attempting to pair the Shelly BLE device via HA in encrypted mode, just press the physical button of the BLE device first, then enter the 32 char HEX encryption key from the Shelly BLE debug app and - it works!
Let me know if that helped

I tried it. It’s not working. The key of the debug app is not accepted in HA. Anyone else managed to make it work?
