Failed setup - Modbus error

[hibberts]

WillCodeForCats, thanks for this. I’m new to the HA platform and got it just so that I could control my SE system. It’s taken bit of learning, but I’m getting there. I’ve installed the program but get the following warning

If there is anything that you could recommend that would be greatly appreciated
Thanks RH

I am seeing the same error, but mine uses port 1502. Did you ever figure this one out?
