I have 3 TRVZB–1s, updated to firmware 1.1.5. After the last update they no longer pair with the Ewelink APP with Z\_Bridge-P or ZBridge, but only with NSPanel86PW.

Hey

Original ZBBridge doesn’t support TRVZB. But it should work with the newer Pro. May I ask if you have 10 end devices on this bridge? It is the limit if you have no router devices; in this case, you can not add more end devices.
