I thought I finally got my outdoor temperature sensor to work, and it did for a few days. I positioned the bridge so that the signal only needed to go through a double pane window and the clear side of my greenhouse. The distance is 97 feet. Today, the sensor disconnected, so I went out and replaced the batteries, putting in new lithium batteries. It took awhile, but it connected again for a little while, but has disconnected again. The only things, besides the window and greenhouse plastic side are a few branches of trees, but sighting between them, there is almost a clear line of site. I could use any suggestions at this point.
