Honeywell integration stops working with blacklist error

[jody.albritton (Jody)]

I was maintaining a device type for honeywell for a few months and I abandoned the effort because honeywell now expressly forbids accessing their cloud services in this way. Here is my post from March 2015.

Honeywell Smart Wi-Fi Thermostat Compatibility

If you polled/refreshed a few times trying to get data, you could have been temporarily blocked by Honeywell. If you have accepted the new ToS, you know they do not want people using unauthorized methods of accessing their own data. I have heard there have been talks between ST and Honeywell, but I don’t know if or when anything will come of it. Until then, you need to know it could stop working at anytime.
