Hi all,
I have 2 ZBT-1 sticks in my system: one for ZHA and the other for Matter. After an update in which I updated several components, ZHA no longer works. The integration reports “Setup error: serial port is locked by another application”. Neither reloading Home Assistant nor restarting the system helped.
Even unplugging and replugging the two ZBT-1 sticks did not change anything.
When I try to reconfigure ZHA, I get the error message: “Connection failed”.
There is also an error message when I try to flash the firmware (7.4.4.1): “The action update/install could not be executed: failed to flash firmware”.
What else can I do to make ZHA work again?
