Question

Hoping someone could help me out here. I've inherited this system in a house I've recently purchased. It looks like the system was sometime in 2023. Anyway I've followed the instructions under the connection methods section with an LM2956. I've attached a snapshot of what the PAI interface in homassistant is seeing.

Logs (if required)

I've had a look through the forums and tried swapping the rx / tx pins however the panel doesn't even get identified by the add-on. Baud rate is set to 115200 as shown in the other forum posts. I've ordered a logic level converter as the 2nd serial port seems to be outputting a 5v signal. Any other ideas of what I could try?

Panel identified this means that connection is established and baud rate is correct.
Problem can be in encrypted serial, but I am not sure.

Yeah fair. I'll reach out to the installer to see if the panel is locked.
