Since the system auto-connects after a power outage, what is the point of the return air sensor? I don't know how or whether to install it.

The return sensor is a temporary backup to the battery powered thermostat. For example, the batteries could fail while you are away on an extended trip. In this situation, the EIM can keep your home from freezing with data from the return sensor. An extended power failure is a different story. In this situation, you would need a backup generator to power the HVAC and the EIM. After a temporary power failure, the EIM will reestablish communication with the wireless devices automatically. It does ,however, take some time.

You could kill the power to your HVAC system temporarily and see if Honeywell emails you. Or open up the app after power is disabled and see what it does. I remember getting an email message every hour about no internet access to the stat. It depends how you setup the frequency of messages. I hope that helped

I plugged it into an outlet that is controlled by a switch. It came back on automatically when I switched it on and off. I'm guessing that means that it will also turn on automatically after a power failure.

Make sure bits of paper arent clinging or stuck in a place such that they would prevent the sensor from sensing. If u are handy. take the cover off and make sure a wire hasnt come loose or anything gone awry. If so, fix it! But most likely ur unit needs to be replaced or repaired by a Service Tech. I'm assuming its out of warranty - if not contace Royal. I had a small problem when mine was new and the resolved it over the phone.

Sensor must be removed to add air.So you must unlock to add air.I never use them . PitBoss.

Aim directly at the sensor & make sure the connections are fully plugged in. You could also contact customer service- Worst case scenario, return it & get another one.

You should definitely turn off the power before you hook this up. If this is hooked to your alarm panel its likely powered by the transformer in the alarm panel. What I did is called my alarm company, asked them to put my system in test mode and let them know that I was powering down the alarm panel. I turned off the breaker for the alarm panel, and then did the sensor swap....Powered the system back up and called the alarm company to put the system back into active. mode. Risky that you damage the new sensor if you try to hook it up with the power on...I don't recommend it.

There is a setting to reverse the sensor status. Out of the box it said the door was closed when open, etc

Good morning. I regretted having bought this alarm. It was a waste of money and would have returned it if only I could at that time. I hope this answers a question in your mind about the reliability of this sensor.

Just reports humidity. My humidity sensor is so-so and doesn't work after an extended period of time (24hrs). So basically I leave it off

I had no problem with mine. Simply connected to post and has worked great. Suspect sensor not working. Get a new one and do not worry. Good luck

If you can add a sensor you can add this to your system. If you dont have the password to do so your monitoring company should have it. This has a plug in wall transformer with back up batteries to power it. It will not run long on the batteries so it needs to go someplace you can plug it in. I mounted above an outlet, poked hole in drywall and ran the cord in the drywall and back out behind the plate over the outlet.

I have a 12k BTU unit and it has automatically come back on after an outage of about a half hour.

Can't say that it will happen 100% of the time, but I just experienced this last weekend, was away for a couple days, got an email saying the thermostat wasn't able to connect to the cloud site in over 24 hours, Called my neighbor, he confirmed the power was out, but by the time I got back home everything had returned to normal, the power came back on and the thermostat reconnected without issues. But when dealing with wifi and the amount of variables you could be dealing with with any access point, I'd guess your mileage may vary.

I have the sensor wire wrapped around my hot water heater. My daughter dropped juice on the floor and the sensor wire. The alarm sounded and the only way to stop it was to disconnect the modular plug at the unit. After I dried everything, then reconnected the wire and everything was good to go.

No, it only alerts the system. You can connect an alarm to a controlled outlet and switch it on automatically when the contact is opened or the sensor is moved

You can connect the appropriate sensor to the central unity using the wired outputs in the back (look for sensors with standard normally open/closed outputs). You can connect these sensors to the Mace Door/Window Sensor as well, replacing the magnets for the temperature sensor and using it as a remote control to call the central. If the power goes out it will remain working as long as the 9v battery lasts.
