Honeywell TCC IFTTT Driver

This is a Driver for Hubitat that supports controlling a Honeywell Total Connect Comfort (TCC) Thermostat via IFTTT. Honeywell wants to be mean and not support integrations with other home hubs, but they will integrate with IFTTT. Thankfully, IFTTT supports webhooks so users can make their own calls. This driver uses (abuses?) the ability to use webhooks to control devices which you've integrated. This specific example works for my Honeywell Prestige Thermostat, but it may work for others.

Limitations

You're not going to get all thermostat functions. You won't be able to see what the temp is, but perhaps you have another sensor on your Hubitat hub that will give you that. All I really wanted to do was adjust temps, do permanent and temporary holds, and then resume the schedule - so that's all this does.

Commands Supported: setHeatingSetPoint (permanent or for X hours) setCoolingSetPoint (permanent or for X hours) setFollowSchedule fanOn fanAuto

So you'll essentially have to (well, you have to create the ones you want to use) create 7 webhooks per thermostat you wish to control.

Installation

1. IFTTT Account. You need to connect your Honeywell services to your account. Grab your API key from here - it's the part after the ''/use/'' in the URL.
2. Create a ''New Applet''. For ''This'' select Webhook. Click on the box ''Receive a web request''.
3. For your event name, you'll make it be ''device''-''command''. For instance, I have two devices - upstairs and downstairs, and we have 7 commands per device. So the first webhook I create will be ''downstairs-setCoolPerm''
4. For ''That'' select ''Honeywell Total Connect Comfort''.
5. Then select the function you're creating - for this example, I'd select ''Set temperature to a permanent hold''. Then select the options for your thermostat (which thermostat, cool or heat). For ''Target Temperature'', delete the field completely and click on ''Add Ingredient'' and select ''Value1''. Then select ''Celsius'' or ''Fahrenheit''. For your recipies that need two variables (the hold for certain time), set ''Value2'' to be that variable.
6. Click ''Create Action''.

Optional: Enable notifications to verify things are working, but you can just use the TCC app or website or thermstat to verify, because you'll eventually turn them off.

Your events should look like this:

Next, install your driver.

1. Go to the raw version of the .groovy code on Github.
2. Go to Hubitat -> Drivers Code -> and paste the code in from above.
3. Go to Hubitat -> Devices -> Add Virtual Device
4. Scroll to the bottom of the list and select ''Honeywell TCC IFTTT Thermostat Driver''
5. Configure your command names to match what you configured above at IFTTT. It should look similar to this:
6. If you want to do perm holds unstead of holds for a # of hours, adjust your ''Hold#'' number, otherwise, all your changes will be permanent until you do a ''setFollowSchedule''.
7. Check the logs to see if things are working, if so, turn off debug. Remember, not everything works just what's listed above at the top of the page.

Questions

Q: What if I want to do permanent holds and temp holds? A: Setup two drivers per thermostat, use the same webhooks, but change the driver options.
