    Multi-zone ready.

    You don't need to have a mansion to benefit from a multi-zone thermostat system. With the Insteon Thermostat, you can connected up to two additional Insteon Wireless Thermostats for remote temperature monitoring in your home. Place one in the hottest room in the house and use it as a basis for cooling your home. Add one to your guest bedroom and let the in-laws have a say in household temperature. Or simply move the temperature sensing from a dark and deserted hallway to the center of your home.

    Working well with I/O Lincs Review by Lou
    Working well with I/O Lincs
    Rating

    Bought with an I/O Lincs to replace an older Totaline type unit.

    Thermostat package is larger than it probably needs to be. Radio range seems fine (it is only talking to other wireless Insteon devices, not via wireless to the I/O Lincs, which supports only power line communications).

    Backlight is bright and displays are clear and make sense ("Heat" mode vs "Heating" when calling for heat...nice!). Totaline did not display when it was calling for heat.

    Main drawback is no program running when on batteries only, which the Totaline did. But the superior user interface makes it acceptable in our use case. Might be a deal breaker in some other situations. Using an external power supply kills the portability factor, although it does still eliminate the need for wiring to the furnace room.

    Insteon App with Hub apparently cannot communicate with the thermostat when it is on battery power. Pretty dumb really, as that is an expectation for Insteon devices. It should be talking to the Hub periodically which could cache communications with the thermostat.

    Using the external sensor to monitor temp of the pool water. This is working well.

    Reverts back to Slave Mode Review by BigDigger
    Reverts back to Slave Mode
    Rating

    I decided to install the Wireless Thermostat at another location in my house and soon discovered that it keeps reverting back to slave mode. Apparently this is a known issue that goes back a few years according to the link below. This is a big disappointment as this is one of the primary reasons I purchased this thermostat. Smarthome needs to step up to the plate and fix this bug.

    Worthless as a remote thermostat Review by dfwniceguy
    Worthless as a remote thermostat
    Rating

    I purchased two of these to use as remote sensors for my two thermostats. I had been using a similar setup with a different manufacturer and had high hopes that these would work as well and would also allow me to use my Insteon setup to give me remote connectivity to my thermostats. My thermostats are placed in locations (hallways) that do not give an accurate reading of the temperature inside the rooms they are meant to control. By using remote sensors, I am able to more accurately keep the rooms at a comfortable temperature.

    What a disappointment! Unfortunately, the remote unit consistently reverts to being the "slave" thermostat. Sometimes the two will maintain the proper "master/slave" relationship for a few days, sometimes they work properly for a few minutes.

    I worked with the Smarthome tech support guys and tried a number of experiments, none of which resolved my issue. You can literally place the remote thermostat next to the wall thermostat and they will forget their "master/slave" relationship.

    When the tech support guys told me that nobody else had reported similar problems and that there was nothing more that could be done, I decided to replace the thermostats with the previous non-Insteon models that were working fine.

    I would definitely recommend that you not purchase these for use as a remote thermostat.

    Exactly what I needed Review by Luke
    Exactly what I needed
    Rating

    I needed a thermostat upstairs to operate a second zone I just installed (with electronic dampers and a zone controller), but I didn't want to fish wires through the wall. So I wired up an Insteon thermostat to the zone controller and put a portable Insteon thermostat upstairs as the master. This works like a CHARM. It is exactly the solution I needed and I have no complaints whatsoever.

    Works well; but try to use it with the newer 6v power supply Review by Luke
    Works well; but try to use it with the newer 6v power supply
    Rating

    I'm using this to control a HVAC duct booster fan in order to pump air to my finished attic. It works very well for me. It has been reliable though it has failed to turn off the booster fan a couple of times (rare though). The device is far away from the relay (2 floors away) so I suspect this would work better if closer or if I had more devices.

    Pros:
    - Looks nice
    - Temperature and humidity readings are accurate (I cross-checked it with some other sensors)

    Cons:
    - Doesn't have a good way to turn on the backlight. It comes on when you press a button on the thermostat (such as the temperature up button) but that means you have to increase the temperature to get the backlight on. I believe newer ones have fixed this by making the set button accessible without opening the cover.

    Other thoughts:
    - I am using this with the 6v power supply so that I can query the temperature remotely. The device seemed to intermittently respond. However, Insteon sent me an newly designed power supply (without my asking) and the device works more reliably now.

    Works perfect Review by GeorgeG
    Works perfect
    Rating

    I use this as a wireless controller for 2 space heaters which are plugged into 2 Insteon outlet modules. Works perfect and is like having central heat with very precise control. If you want this to control your central HVAC system you need to start with the wired controller and use this as a remote sensor/controller.

    Not Good for Standalone Use Review by Heavy Insteon User
    Not Good for Standalone Use
    Rating

    This thermostat does not work as described as a stand-alone thermostat/temp sensor device controller. I purchased 3 with very high hopes -- none worked and with many tests were conducted. I've got a couple hundred Insteon devices in normal scenes and/or controlled by ISY so I'm not a novice.

    It may work fantastic when linked to the wired version but is worthless stand-alone.

    Received mine this week. I want it to communicate with home control software so I need to go the external power route as on batteries it goes to sleep and won't take external commands.

    Similar to what Smarthome sells, I tried a 6VDC/800mA but the humidity was jumping all over the place. This has been documented in other online forums. I tried several more adapters rated as 5V. If they produce less than 5.09V then the external sensor doesn't appear to work correctly.

    The solution that finally worked for me was the genuine Apple iphone square wall plug rated 5VDC/1A and a usb cable stripped at one end for +/- power. That produced 5.19V and now the humidity is stable and the external sensor is also stable. Hopefully this can help others facing this same problem.
