I managed to get two add on sensors to read on my indoor display, part of system model 01536, but I cannot get them to show up as available sensors in the browser or smartphone apps. The only sensor showing after an hour is still the original 5-1 that is part of the original system. So I can read remote sensors from the local display but I cannot see them using MyAcurite. Can someone please advise how to remedy this matter? Thanks.
