I've had the TL-300 and around 10 sensors working since 2010 and those located outdoors have been showing temperatures below zero C many times. However, we just moved house so the whole system has been powered off for a few weeks and now that I've placed the sensors around the new property, every sensor I've placed outdoors stops displaying a graph trace when it reaches zero celcius. I have two of the small button cell sensors (with new batteries), a TL-44 ext and a TL-3 and all of them now stop displaying at zero. The graph Y axis is set to -6 to 38C and I can't see any setting that would prevent temperatures below zero from displaying. Every time the temp goes above zero the displayed traces are fine.
I'm using software version 1.8.7 and its been installed and working fine for 6 years. Any ideas what's up?

Hello,

Seems batteries give a problem below 0 degrees!
