Thank you, sir.
I just installed the T6 Pro on a 2 wire steam boiler. Unit is running on battery, so I suspect that is going to introduce some limitations. Generally, it just doesn't seem like it's responding very well and/or quickly. The device is paired, but this doesn't look great:
PER: 0, RTT Avg: 99ms, LWR RSSI: 13dB
Neighbors: 4, Route Changes: 210
I did pair it with S2 security...perhaps I should repair it without the security?
Put a repeater somewhere between it and the Hubitat? They're not that far away, but there is a wall and floor between them.
Yeah that's a huge distance issue. I would certainly introduce a repeater.

It's literally less than 20' straight line distance.
Joists, studs, flooring material, and drywall raise that linear distance by 30-50 feet. And it’s much worse if the material in question is plaster.

be nice if the current state would alert when the filters need to be changed out then I could make a rule to alert my phone

I’ve been looking at that for a while and have yet to capture an event that corresponds to the alert showing on the thermostat…

Fair point.
ok... its one thing I really wish for!!
And brick/concrete/metal siding.... those really reduce zwave/zigbee signals

@thebearmay Home == !Away, Away being the heating/cooling eco-modes whose set points are determined in the T6 UI's Away Settings menu. I did notice that there appeared to be command stubs in the driver for setting Home and Away modes that have yet to be fleshed out.
According to Honeywell's Z-Wave spec Away and Home can be set thus:
Basic V1 (basic set command implementation):
* Value 0x00 Device goes to Energy saving setting (AWAY mode)
* Values 0x01-0x63 and 0xFF Device goes to Comfort setting (HOME mode)
According to both the Honeywell User and Professional Install Guide the only way to switch this parameter when the T6 is included in a Z-Wave network is via these Z-Wave commands; for whatever reason Honeywell decided switching Home/Away should be disabled in the UI for the Z-wave use scenario, even if you are still using the high WAF on-device scheduling like we are. ¯\_(ツ)_/¯
Adding Home/Away capability to the driver would be a big deal for our household because we'd like to hook this kind of automatic thermostat control into our HE Mode Manager's "Vacation" mode functionality.

That’s the piece I was looking for… TIme to play and see if I can make it work.

An interesting aspect to this is that there don't seem to be any device settings that distinguish between "eco-cool" and "eco-heat" mode...
Take a look at theHoneywell Z-Wave Spec and see if you see any other intriguing technical tidbits!
v1.2.19 should have working Home and Away modes now

Thanks, works great! Now I would like to figure out the simplest method for exposing this parameter to the Amazon Alexa Skill for complete thermostat voice control but that is another topic.
Off the top of my head possibly a virtual switch with a couple of rules:
Switch on Thermostat Command Home
Switch off Thermostat Command Away
Yes I typically have taken this approach and my Device list is cluttered with virtual switches and devices whose sole purpose is to serve as Alexa proxies.

This is the way.
So it turns out that the Alexa thermostat API already does support a value of ECO for its thermostatMode property in addition to the standard AUTO, COOL, EM_HEAT, HEAT and OFF.
And when I asked "Alexa, set the thermostat to ECO mode" it actually responded "Thermostat is set to energy saving mode" - but then set it to 40F with heating mode still enabled 
(Strangely, subsequent commands to set ECO mode elicited the same verbal response but no change in the heating set point... )
I wonder where this arbitrary 40F setpoint is coming from? Sounds like it may have been hardcoded into either Hubitat's Amazon Echo Skill app or the AWS-side Hubitat skill itself back in the day when existing Hubitat thermostat drivers didn't have a way of supporting a thermostat's native ECO/AWAY mode.
Now that we have that, though, it would be nice if the app or skill was updated to map the ECO value of the thermostatMode property onto AWAY status in the T6 driver and in other thermostat drivers that support energy-saving modes.
