Decreased timeout in self.session.post() causes HTTP Timeout error

[eataiwo]

I recently installed the PSU Control and PSU Tapo plugin. Initially, I couldn't get the plugin to work with my plug, so I copied the code onto my laptop and started playing around with the code to see any errors, as I am not sure if Octoprint logs these. On investigation, I got the error below. If I change the timeout for self.session.post() on line 55 of tapo.py back to 2 seconds rather than 0.5, the script runs fine, and I can control the smart plug. As this prevents the control of Tapo devices with no apparent error the other issue #2 where control is not working might also be solved.

Thank you ! This worked for me as well. Before:

2022-10-09 20:54:12,111 - octoprint.plugins.psucontrol - INFO - Switching PSU On
2022-10-09 20:54:12,712 - octoprint.plugins.psucontrol - ERROR - Error while executing callback <bound method PSUControl_Tapo.turn_psu_on of <octoprint_psucontrol_tapo.PSUControl_Tapo object at 0xb2242ef0

...
  File "/home/pi/oprint/lib/python3.7/site-packages/requests/adapters.py", line 578, in send
    raise ReadTimeout(e, request=request)
requests.exceptions.ReadTimeout: HTTPConnectionPool(host='192.168.86.27', port=80): Read timed out. (read timeout=0.5)

After bumping the timeout back to 2s:

2022-10-09 21:04:45,756 - octoprint.plugins.psucontrol - INFO - Switching PSU On
2022-10-09 21:04:51,276 - octoprint.plugins.psucontrol - INFO - Switching PSU Off

I reverted the timeout
