Interesting way to tackle this @cswheelock.
My main goal here is to enable me to quickly 'hold' the office on vacation days when no one is there, or to hold certain zones (or all 3) of the house when we're out for the day on a weekend.
Trying to be able to simply say, "Ok Google, Hold House Thermostats" and then have Stringify run a flow to trigger a permanent hold. I can then, "Ok Google, Resume House Thermostats" and have it resume normal scheduling.
Not a HUGE pain now, but I currently have to multiple IFTTT 'applets' to:
Hold Kitchen AC
Hold Family Room AC
Hold Upstairs AC
Hold Kitchen Heat
Hold Family Room Heat
Hold Upstairs Heat
Resume Family Room
And then have multiple Stringify flows to trigger each of these, as well as groups if I want the whole house. Not insurmountable, but would be quicker / easier with the ability for Stringify to set a PERMANENT HOLD temp thru Honeywell, as well as RESUME.
Currently it only sets a 'temporary' temperature until the next Honeywell scheduled time. I can see why you remove the scheduling!
Always a work around (well almost), appreciate your solution, and will use a little duct-tape to get this working until Stringify is able to add add'l Honeywell integrations.
