Does adding the Honeywell C7089R1013 Wireless Outdoor Sensor help the performance of the thermostat? Or is it only to display outside temp and humidit

As i understand it, it only displays outside temp and humidity. I already have a good gauge to do that so i didnt buy that add on.

Far as I know there are no physical "add-on" sensors for the thermostat, nor any place to connect them. The unit relies on weather-based reporting data via a wifi network for outdoor/remote sensing based on zip code and are not specific to the thermostat's "exact" mounted location. It does have it's own temperature/humidity sensors integrated on board for specific mounting location temp/humidity readings that vary slightly from the wifi readings.

a reply from a Honeywell representative: "Our thermostat's gather the outdoor air temperature from Accuweather.com, which does appear to have a slight difference in temperature from Weather.com The thermostat updates the outdoor temperature every hour, so that is why there is a difference of a few degrees As far as the indoor temperature, our thermostats do read temperature a bit differently than typical thermometers. Our thermostats take both surface and ambient air temperature, and calculate an average between the two readings. Because of this, the temperature reading on our thermostats may be up to 3 degrees off from other sensing devices." Honeywell needs to do something with the outside temperature feed. I don't believe it updates every hour since it got stuck at 50 degrees yesterday while the actual outside temperature was well over 70 degrees for several hours already. At minimum I think the outside temperature update should occur every 30 minutes.

It seems to depend upon whether you are using the outdoor sensor or not. Because the unit is usually in a furnace room, it will naturally read slightly differently than in an open space.

Probably not all this does is adds a remote thermometer that turns it on and off overriding the built in one. If the temperature drops to below what you set it simply will not turn on the unit and the inside will match that of the outside

Not for this model. All you need is Wi-Fi. The thermostat connects directly to your Wi-Fi router / access point. When you do the initial setup you choose the SSID of the Wi-Fi network you want to connect to and enter in the password. From there it connects directly to Honeywell and you can manage it from their website or phone app. Some people have noted issues with it disconnecting from the network, but if you force WPA2 that should resolve it.

This thermostat is not Wifi capable. Honeywell's line of Wifi thermostats will have WF in the model number where this one has C. WF indicates wifi. They also make a line of thermostats that can be used for wifi if they have the Honeywell Gateway installed with it. But, again, this model is not capable of that.

you would have to ask Homedics about that. frankly, I could not get the outdoor sensor provided with my unit to work at all. I finally had to return it for credit.

The sensor and display are all one unit (the display and indoor sensor has the green screen, the other sensor show as a white square is for outside), so if you want to monitor the crawl space you need to have the display located inside the crawl space. If it were monitoring your crawl space humidity and it kicked on to add moisture the humidifier it would also kick on your furnace blower to circulate the humidity in your entire house (not just the crawl space, unless you have a separate system for your CS). As for 3. I am not sure, I don't have an issue with too much humidity because I live in Colorado and I don't use the a dehumidifier function.

Yes, you can name each thermostat separately assigning sensors to whichever thermostat you wish. We have 2, we have one outdoor sensor that is read by both t-stats and a handheld remote that will control either...

No , that is a 'Retail' thermostat , I don't believe it is RedLink or compatible with remote sensing capabilities. You would want the TH8321R stat.

The heating device makes no difference (as long as it does not draw too much power -- check specs); the only complication is the temperature sensor and how/where it is placed. The Honeywell unit does not come with a sensor and it will be tricky, but possible, to get the correct one from Amazon.com. I just used my old sensor, but had to experiment a bunch to find the needed series resistor to use with it to get it calibrated to the Honeywell unit for the small temperature range we cared about. I had installed the old sensor in a tube under the floor just under the tile and floor mats -- I had easy access from the basement ;-) The heating device makes no difference (as long as it does not draw too much power -- check specs); the only complication is the temperature sensor and how/where it is placed.

Yes, I am using it in the humid environment. The thermostat has been working as expected.

The outdoor sensor is wired into the controller at the designated terminals for outdoor sensor. The controller is wired into the thermostat and furnace for automated control per the instructions in the IOM manual supplied with the controller.

Using the Ecobee Remote Sensor Module it will support remote sensors. however if you want to use them to do zoning you would need a traditional zoning board and such. You should be able to find it online, I also found an unused module one this week if you need one, changed out my Ecobees for a manufacturer mandated thermostat on my new variable speed HVAC.

I have it indoors with the sensor out doors. I am having a problem with the outside reader on the screen. It gives me readings like 11.8 or 12.2 for outside temp and I do not know why. I think that I would not buy the same model again. I have no problem with rain on the sensor.

It's not cheap, but I upgraded from this thermostat to a Honeywell YTHX9321R5061 Prestige 2.0. It works with my heat pump. It has an outdoor wireless temperature sensor. It has a wireless remote with remote temperature sensing, too. With an additional module, you can control it via the internet. If you can afford the unit, you'll love the way it works.
