I have had my SmartHub and 5in1 installed for several months. Both work fine, except signal strength on hub is low (1-2 bars). Generally, it works fine anyway, but lately it's been showing signal loss for up to 6 hours at a time. I tried moving the hub closer to the station; I tried reorienting the hub is a couple of positions; each time I change something I waited to ensure that the readout was updated. In all positions, and at all distances, it shows 1-2 bars. I can understand that full strength might be difficult to achieve; however, I can't believe that no matter what I do I only get 2 bars. I see others are having connection reliability issues, even from 15' away. Do you have a fundamental problem with the 5in1 transmitter? I am using new Eveready Lithium batteries as recommended.
