For those of you that have sensors dropping out while driving.
Are you using any wireless digital thermometers? Typically these wireless thermometers operate at the 433Mhz frequency the same a most TPMS systems. They do cause interference.
I have a wireless thermometer with three remote transmitters. I was having a lot of sensor dropouts until I found out about the wireless thermometers causing interference. I have the TST 507 system and called TST about this problem. I talked to the owner and he acknowledged there is an issue with these wireless thermometers. The fix was to install a repeater. Once I did that no more problems with sensors dropping out.
Ive got the 507 system and I also have a wireless digital thermometer (i keep the remote sensor in my outside entertainment bay & the display receiver in the master suite) and don't have an issue.
our coach is full of metal (all the basement bays are metal boxes w/ aluminum doors), the floor has a metal sheet and theres quite a bit of steel framing)....initially i had trouble w/ ONE sensor periodically dropping out (on our jeep), i thought it was because of the 40+ feet length from display to the sensor so i added the repeater....later i wound up talking to TST & replaced the battery and I've never had another problem.
