Problem
Customer could not configure Comcast wifi and his Honeywell T9 wifi thermostat so he could have remote access to the thermostat on his iPhone.
Solution
Major problem was nearly no documentation from Honeywell on setup specifics. Problem was within the Comcast configuration. Reconfigured the Comcast network so all the relevant components would connect with each other. Once done, thermostat could be added to the Honeywell app on the iPhone and remote access established.
