They are obviously full of it. Still, the redesign looks nice, and I like the built-in air quality sensor.

Doesn't look like it has Alexa built-in anymore... But yes, the built-in air quality sensor is a nice touch.
Updated: I'll take that back

I have an Ecobee 3 with Alexa built in. It connects using WiFi. My system has remote room sensors to report occupancy. I have no idea how they connect to the Ecobee hub. They might be using Z-wave for all I know. The sensors can be used within Hubitat using the Ecobee integration. I do not know if they could connect directly.
Current sensors use the 915 MHz frequency to connect to the thermostat, which is not the same as Z-Wave.

Correct. 915-927 MHz using zigbee (channels 6-10).

I'm confused , Zigbee is 2400mHz ~ 2480mHz
That range covers zigbee channels 11-26. Channels 0-10 are from ~868-928 MHz.

Wondering if this is worth upgrading from the 4… I’m not interested in paying for any of their subscription choices. Have most of those covered with hubitat.
And it went live ...

Thanks aaiyar. I guess in the HA space the lower channels aren't that common?
It also appears they have 1/4 the data rate of the higher channels.
As far as Ecobee, I have the 3 with Alexa built in, and given their server issues, I'll never purchase their products again. Actually have a Zen I'm waiting to replace my Ecobee with
Yup. There are a several custom applications, but the most commonly known is ecobee using the lower channels for its sensors.
Oh really? I have a nest I'm happy with, but have been considering a upgrade to Ecobee.
Has it been that bad?
"that bad", well I would guesstimate about 3-4 events/year. Given the price and the brand, I expect Google like reliability. And if you search the forums, you'll see issues with the integration. I removed my integration.
Given its price, I wouldn't buy again. Looking forward to swapping with a Zen and using HE to automate/schedule it.
Thanks for the info, I ASSumed it was RF 433 or 315, but I was wrong.

For what is worth, I switched to Ecobee when Google decided to shut down the Works with Nest and I maybe recall one Ecobee outage since 2019. But again, I don't pay attention to outages that don't directly impact me.
But I van tell you that I remember more outages with Nest in prior 2 years before I switched.

I would agree with that estimate.

I have used Nest Thermostats for 7 or 8 years and have not had an issue in my home. Did have one of a client's go out (1 of 4!!) - simply refused to connect to WiFi or complete the setup. Also never experienced a cloud issue BUT that is not saying I didn't have one.
Have installed maybe 20 or so Nest thermostats (of different models) and a ton of "smokes". They are overpriced for what you get but I have never had a call back from a client 
.
Having said that Google's seeming hostility to third party vendors is really making me reconsider also tired of fighting with electricians - "Wireless Interconnect" IS code compliant actually.. and yes I'm happy to work with the client for setup and take responsibility.. 
I'm not sure I'd be into Ecobee either.. the cloud thing bums me out for both systems.

I had ecobee thermostats from 2011-2019. I prefer the zwave+ GoControl that I currently use.

I have been pretty happy with my Ecobee. Maybe there has been some outages, but none that I recall have ever really had much impact on me.
I run a schedule and use Sandood's Ecobee suite to modify the schedule to start or stop comfort settings earlier or later, based on presence and other events. Has worked pretty well IMO.
I switched away from nest to Ecobee.

Prior to Nest I used the Honeywell Z-Wave, my FAF went up with Nest and increased further with Ecobee. Not sure if Google changed how things work, but remember outages kept me out of the thermostat in the home, that's not the case with Ecobee, their schedules run and so is local control. The only time you may notice cloud outages, if you are away and want to adjust your thermostat. Luckily I didn't encounter any outages when I set the thermostats to away. Other than that, Ecobees just run. Funny that I had to replace the Honeywell thermostats so I can be able to use a Honeywell multi zone controller.

Which one is that? I currently have Ecobee, and am considering switching for a z-wave thermostat.
