Can't Get Venstar Integration to Work With T5800

I am brand new to HASS, so I hope I am posting this in the correct place.

Based on the following github post it appears that Venstar integration worked with the T5800 thermostat back in 2018: https://github.com/hpeyerl/venstar_colortouch/issues/4 (unless I’m mistaken, which could be the case…if so, please let me know).

I have tried to integrate my T5800 with Home Assistant, but with no success so far. I get the following error in my logfile:

2020-05-10 17:08:13 ERROR (SyncWorker_8) [venstarcolortouch.venstarcolortouch] Error requesting https://192.168.0.11/query/sensors from Venstar ColorTouch.

I also get the following associated error:

2020-05-10 17:18:23 ERROR (SyncWorker_0) [homeassistant.components.venstar.climate] Failed to update data

I have enabled the local API on my thermostat, and it appears to have one open port, specifically port 80. If I point my webbrowser there, I get the following text:

{“api_ver”:5,“type”:“residential”}

Any and all help would be greatly appreciated. The thermostate integrated easily with google home and alexa through “skyport”.

Thanks in advance!

Did you ever find a solution to this? I seem to be in the same boat.
