5-in-1 sensor not available

I received a 5-in-1 with SmartHub for Christmas.  I temporarily set up the device by building a mount in the yard.  I'll install on the roof once I get some better weather.  I set up everything and it all looked great.  Until last night.  I received notice that the 5-in-1 had not updated for over 2 hours.  An additional temperature sensor was showing fine.

I thought that maybe the temperatures were the problem.  It was down to about 7 last night and thought that maybe the alkaline batteries were the problem.  Since this is a temporary install, I installed the remote battery thing and ran that into the house.  The battery was showing normal and the signal strength was showing poor, both before and after installing the remote battery.

Doing further troubleshooting, I removed the additional temperature sensor and it immediately showed on the available sensors.  I then removed the 5-in-1 and this sensor does not show on the available sensors, it's now been about an hour.

I've also reset the SmartHub.  I'm still only seeing the additional temperature sensor.

Here's a shot of where the display is and just 20 feet back is the 5-in-1 sensor.

How does the sensor communicate to MyAcurite?  Does the sensor talk to the display and the display talk to the SmartHub?  Or does the sensor talk to the SmartHub directly?

2 hours after I removed the sensors, the 5-in-1 is finally showing up as an available device.  Temperatures are in the mid 20's.  I'm not sure if something froze up.  The signal strength is still showing as poor.  The 5-in-1 is about 30 feet from the display.  The additional temperature sensor is at least 50 feet away, through the brick wall of the house and through the metal wall of the car port but is showing strong signal strength.

Hello Gregory,

It sounds like your 5n1 sensor stopped transmitting. The sensor communicates with the display. You should always have 4 bars on the display. If you have less than that you are missing data packets which is how the signal strength is measured on the display.  The smartHUB communicates with the sensor as well. It provides with the true quality of signal strength it is getting from the sensor.  You need at least 1 bar of signal strength to communicate on the display. I would recommend mounting the sensor higher up or picking it up from where you have it. You do not want all the moisture getting inside the sensor with it being that close to the ground. We recommend at least 5 feet in the air.

It will be mounted on the roof.  But it's too cold to get up there and the ground is frozen solid right now.  I will attempt to find a way to raise it up off the ground more.

I found the issue over on WX forum.  Unfortunately the documentation is not clear on how things work with this system.  I was under the impression that the sensor transmits and the display would receive.  But I also thought that the display would relay that to the SmartHub.  But the SmartHub receives from the sensor and the display does no transmitting.  The problem is the SmartHub is in the basement network closet. This gives almost line of sight to the additional sensor through a window, but the 5-in-1 sensor signal has to travel through several walls including a brick wall.

Hello Gregory,

That is correct. The display does no transmitting. The smartHUB and display are receivers only. The sensor will communicate with the indoor display. The sensor will also communicate with the smartHUB. The smartHUB and display will not communicate together.
