I have the ISS in the garden + a transmitter for a 2nd thermometer I use for grass temperature and the transmitter for the anemometer. I've checked the two batteries in the first two and they seem strong, so short of having to go on the roof to check the 3rd one I was wondering whether it was the batteries in the console itself, although this is plugged into the mains?
Any thoughts before the ladders come out?
