I have a Bios Weather Indoor/Outdoor Wireless Thermometer & Hyugrometer unit.
I cannot get the outside temperature to register on the main unit. I have changed batteries, ensured both units are on Channel 1 and placed outdoor sensor about 7 metres from indoor device. I cannot get it to show outside temperature. Help?

Have you tried turning them on in a specific order? In most cases you should turn on the remote unit first. wait for it to fully boot. Then turn on the receiver so it can detect the unit.

Also some reviews have stated the main unit didn't pick up the sensor unless it was atleast 8 meters away.
