Honeywell T9 Thermostats

@Jimbo.Automates I have 8 Honeywell T9 thermostats which are theoretically Homekit compatible, so I tried your Homekit plugin 2.0.1 to gain access to these. I installed the professional trial version and enabled the generic IoX plugins.

Three of the thermostats are a couple of years old and have firmware 01.05.03. These were discovered by the plugin even without being in discovery mode. I added the homekit code to the configuration page for each one and saved it. All three paired with a TSTAT-XXXXX node and two or three subnodes. Relevant values in the main nodes appear to update and be correct, although the subnodes are mostly irrelevant (T9 thermostats don't have built in occupancy and they are not battery powered) or are not populated with correct data.

The other five thermostats are newer with firmware 03.04. None of these were discovered, even if they were put in discovery mode. I tried to install one manually, but I don't know what the value should be for the Accessory ID since none was discovered and the pairing was therefore not successful. Are you familiar why with these newer T9 thermostats aren't visible to the plugin? According to Honeywell, the T9 thermostats are only compatible with homekit above firmware version 03.xx, so they must have made some kind of change/update at that point. Is there a way to determine the Accessory ID of a device to attempt to force a pairing (although if the discovery didn't find it, a force may not work anyway)?

Thanks,

Dave
