Duplicate Switch Errors

[Incredible-IT]

I had this setup before and it worked pretty well. I rebuilt my control system and reinstalled from scratch. Now when I try to use the duplicate switch script I'm getting connection refused errors. I did modify the script according to directions. I entered the relay ID, username and password. The relay works properly from webpage. The relay is not used anywhere in any enclosures or areas. Help appreciated.

In order to run the script pi@RPi:~/TerrariumPI/scripts $ python3 duplicate_switch.py 100 you have to make sure that TerrariumPI is running.

Secondly, did you change the bind address in the settings page? Because if you did, than I would advise to clear it. It should be 0.0.0.0.

The error is that there is no server running in ip 127.0.0.1 on port 8090.

Thanks! TPi service is running. I had changed the IP to match the IP of the server. I changed it back and rebooted. Now it works.

Ok, but that means you have configure TP om a specific IP address in the settings.

That can cause issues when your Pi does get a different IP after reboot. When the IP changes on the PI, TP will not boot up.
I would keep the bind address to 0.0.0.0 which means bind to all IPs.
