Customer Reviews

I installed it myself, very easy.
Michael Garza
I was able to easily link them up to my home Security system through z-wave and now I can view and control them through the web!

The display is also big and bright, which is a bonus.

The thermostat itself is sleek and nice looking with a clear display.

The ADT Pulse system recognized the thermostat right away. Pulse detected it as GE Security: Basic Thermostat Model IS-ZW-TSTAT-100. The Pulse features work just fine with the thermostat: monitoring temperature, setting temperature, and setting mode (heat/cool/auto/off). Since this is the replacement for the 2Gig Z-Stat CT30 thermostat, I assumed it would have the same features. That is not the case. The CT30 is a 5-1-1 day programmable thermostat, although those features are unnecessary and disabled when you use it with Z-Wave. This thermostat has no programming or set-back controls. That won't matter if you are using it with Z-Wave. However if for any reason you ever wanted to use it without Z-Wave, it just allows 1 constant setting.

This device works very consistently and has a very good Z-Wave communications range. It is able to communicate over twice the distance of any of the other Z-Wave devices I use. Also I have read that if you have a "C" wire connected to it from your HVAC system it doesn't rely on battery entirely for power and then acts as a Z-Wave repeater.

One thing to be aware of. This replaces an older device that was programmable in and of itself without Z-Wave. This device can only be programmed on a schedule using a Z-Wave controller automation. I think the greatly extended battery life of this unit, its great communications distance and its reliability make up for the lack of built-in programmability.

One other point in favor of the new model. I read that if someone changed the temperature settings on the older model that fact didn't get communicated to the Z-Wave controller. With this newer model it does. So if someone in the home changes the settings you know about it remotely.

The 2gig CT100 thermostat is an outstanding piece of technology that actually does what it advertises. The Z-Wave added to my house alarm system on the first attempt. Something I can honestly say I have not been able to with any other Z-Wave appliance I have purchased. The HVAC system can now be controlled from my smart phone. The large backlit touch screen is a welcome change from the OEM thermostat. Also this thermostat gives the option of running from a C wire or 4 aa batteries which are included. I will definitely be looking for more Z-Wave devices from 2gig.

I am new to home automation and needed a simple thermostat that I could control my HEAT through z-wave through my phone and be user friendly enough so that it can also be changed/set directly on the device. While this stat is rated for cooling and multi stages I am only using it for heat in one room of the house.

The CT100 fits the bill and it is inexpensive compared to whats out there. I have it paired with a MiCasaVerde: Vera Lite and I can set the temp from anywhere via my computer or Mobile App and/or change it directly on the stat touch screen. When paired, both the stat and the mobile app is updated in real time with the current temp and target temp (they are in sync real time)

I did run into a rather annoying issue; when it was paired to Vera Lite (UI5) with the most recent firmware update: three stats appeared in my devices, 1 was the actual stat, the other 2 were ghosts. You cannot permanently delete the Ghosts, they come right back. It was fairly annoying as I like easy and user friendly and having useless ghost is not friendly. After researching I found the solution: it was simple:

Log into your VERA LITE UI and goto the APPS tab >> THEN "Install APPS" >> THEN search for MiOS Update Utility >> Install it and refresh and those ghosts are busted for good! Ahh nice and clean now!

As far as programming goes, it's not programmable on the stat itself. You will have to program it on your z-wave controller. Since I don't need a programmable stat that's not an issue for me. If this is important to you know that it can be programmed, I tested it because I like to know what my gadgets can do but know the schedule will rely on your z-wave controller so if that was to ever go on the fritz your schedule will not run.

I wanted to be able to set the temperature at my condo before guests arrived, and set it back again after they left. This product, along with a VeraLite Controller worked perfect for my needs.

Only thing I've noticed: my guests sometimes have difficulty figuring out to tap the up/down arrows on the screen to change temperature. they keep wanting to hit the 'Mode' switch.

Overall the installation went fine, even on my oddly-wired Heating/AC unit. I did have to call the company for assistance on which wire went where. They were helpful.

(SEE UPDATE BELOW) The thermostat on its own works fine. However, when pairing each of the three new thermostats with my Vera3 controller, I ended up with 9 devices created in the Mi Casa Verde control panel. 3 are genuine, 6 are "phantom" thermostats. It appears this is a common issue experienced by other users. I can identify the "real" devices, but having the 6 phantom devices showing in the iphone app and desktop control panel makes things unnecessarily complicated.

UPDATE: After a firmware update on the Vera3, the phantom thermostats are gone. I'm a happy customer.
