2GIG 700 Thermostat

Has anyone used this thermostat and have opinions (2GIG STZ-1)?

Are there any major reasons to go with Zigbee or WiFi vs z-wave that is special for thermostats?

Choice of technology would depends on connectivity and customization options.

  • WiFi would depend on whether the vendor provides a native cloud to cloud integration with SmartThings and I don’t see any right now
  • ZigBee vs ZWave depends on your choice and also feature availability. For example with the Z-Wave version you can use third party custom device handlers like this one which allows you access to advanced features like humidity, energy saver, setpoint limits, advanced configuration, filters etc (depending on what the Z-Wave module supports). ZigBee doesn’t have custom device handler as yet you’ll be using the stock ST device handler which only provides basic capabilities.

Also this device acts like a repeater when using a C-Wire. The Z-Wave module is a 700 series chipset which should give you great range and battery life and would make for a good repeater. The same would go for the ZigBee version. So it comes down to what you want. ZigBee and ZWave would depend on hub connectivity, WiFi version (if there’s an available integration would depend on cloud connectivity.

Thanks for this information a while back.

Is there a way to confirm this is acting as a repeater? I included it while it was wired with the c-wire but nothing is getting routed through it. I can’t recall but I may have also had batteries in addition to the c wire. Perhaps I need to exclude and re-include.

It’s been there since sometime in March and a number of z-wave repairs have happened since.

No way to confirm physically. Some thermostats report that information over zwave the custom DTH above can read and display it in that case
