Mystery Sensor?

  • Updated 4 months ago
I have a newly installed 5-1, Access hub, with 3 Temp/Humidity Sensors. All working fine. Easy installation and setup. Installed each of the sensors one at a time after adding batteries, they each showed up ready to install. (I am using MyAcuRite on a Mac) The next day I decided to check the sensors and rename them. To my surprise, there appeared a 4th sensor default identified as a "Temp & Humidity Sensor". I decided to add it to my account and it has faithfully reported for 3 days now. The temperature it reports is the same as my other outdoor sensors. The humidity it reports is a flat 16%. no variation. I've checked with one of my two likely neighbors who reports no AcuRite or similar devices. I will check with the other when I see him.

I'm wondering what device might be reporting seemingly accurate temperature but seeming inaccurate humidity? Could there be a rogue sensor of some sort that the Access hub recognizes that might account for this?

UpDate: at 10;56 pm last night, the Humidity suddenly spiked from 16% to 88% and has stayed in the 80's ever since. My 5-1 shows Humidity varying from 58% to 91% with a high of 95% during the same time period. Is there an AcuRite sensor that would behave this way?

The 16% (sometimes 15%) typically indicates a temperature sensor that has no humidity sensor element.  Some of Acurite's temperture-only tower sensors will react this way, and Acurite doesn't consider them myAcurite/Access/SmartHUB compatible.

Or it could be a temp/humidity tower sensor that is somewhere normally very dry.  Tower sensors bottom out at about 16% humidity.

Or it could be something else from a different manufacturer that is being misinterpreted.  There are many temperture-related sensors from other manufacturers sharing the 433.92MHz frequency.

George very happy with my new access it has excellent signal strength. My Access is also picking up a tower ,not mine with excellent signal.
The tower temperature and humidity appear normal and acceptable for an outside tower.
 I found its ID by reading the access unit. I will be calling acurite to try to find its location. I am running my hub also and it has a poor signal to the same 5 n 1. But my Hub as been running without fail for almost a year and half.

Interesting, how do you "read the access unit"?
The mystery sensor is still showing up and still showing erratic humidity readings although it's been giving "normal" humidity readings so far today. I've checked with both of my neighbors and they say they don't have any such sensors.

Right I checked with my neighbors also. Mine has to be way more than the 350ft. Mine has to be more than a 1000 ft. to get to any possible neighbors. 
To log into the access you need its IP address. You can find its IP address by logging into your router and looking in the devices table. Look for your Access Device ID (MAC Address). Beside it in the device table will be its IP address assigned by the router. Something like 192.168.0.xx. Just enter that in the URL box on your browser. Similar to how you log into your router.
PS: Acurite doesn't appear, they say, to track their sensor device IDs they sell to customers. The tower sensor I am receiving is 00002474

Hello Roy,

George is correct. If you have another AcuRite product in the house where the sensor only does temperature the humidity will read either low around the 15 or 16% range on My AcuRite.  It could also be a neighbors sensor that is being picked up that the sensor is not compatible as well. To confirm this we would need to know the model number of other AcuRite products in the house, or your neighbors house which we understand you may not know. You can remove it from your dashboard if you would like.

I do have 2 other AcuRtie sensor systems in the house. One is the 00609SBDIA3 unit which includes a humidity function, picture of sensor attached. The temp and humidity reading on the included display don't remotely match the mystery reading on MyAcurite. I also have a model 02044W1 which only does temperature but that one does not match the MyAcurite mystery readings either (picture attached). Finally, I do have a SkyScan remote sensor that reads to my SkyScan clock but still, no relationship to temp readings of the mystery sensor readings in MyAcurite so I have rejected all of these as possibilities. My neighbors within 100 ft. say they don't have any sensors either so I'm about to give up trying to figure this out. Is it possible any of the above are the mystery sensor? Thanks for any help!

Hello Doug,

It is possible. If it is not your sensor I would not worry about it. There could be someone in the area that has a sensor you do not know about. The 2 sensors that you have could trigger that  16% readings. You can test this by removing the batteries from these for at least 2 hours and seeing if the status does go red on My AcuRite as they are offline.
