I have a meteo weather station sm1800 but the remote sender asm30 isnt working - where can i get a replacement

I assume it is a wireless station. If so, there is a procedure to go through to get the temperature sender and the base station to sync up and work. You need to check your owners manual to get the exact procedure for your unit. On my station, I have to remove the battery from the base station, let it power up and within 5 minutes, install the battery in the remote station(s) (temperature, rain gauge, wind gauge, etc.). Also, you must keep the remote station within a certain range for the base to get a good signal. Probably 25 feet, but the owners manual will have the right number. Also, use new batteries.

Check battery status indicator on main weather station of remote unit. If no indication, replace battery in remote unit. If battery is good then check "channel setting" of remote unit to make sure the channel setting on remote unit matches the "channel" setting on main unit. many weather stations will take up to 3 or 4 remote units and they must use different channels to relay the remote imfo to the main weather station unit.

I had the same problem and gave up on the unit for a while, then I had another attempt and found this worked for me. Take the batteries out of both units (receiver and outside sender) then reinsert the batteries BUT put the batteries into the outside sender unit FIRST, this seems to make the difference as when you then put the batteries into the indoor base-station it detects the outside temperature signal immediately as it starts to set itself up .
