Hello, if your barometer quit working also I would believe the console/display to be faulty since the barometer is located inside this, not out in one of the outdoor sensors. If this is the case then the console may not even look for the outdoor sensors. If you do get barometer readings then try (with fresh Alkaline (1.5v or higher) batteries),
(forget the wind and rain gauges for now)
1. Remove the batteries and
leave removed from the console/display.
2. Have the thermo/hygro sensor nearby and
remove then reinsert its batteries.
3 Wait 2 or 3 minutes after doing step 2 then reinsert the console/display batteries.
After a few minutes the outside temperature and humidity should appear if the console/display
is still communicating with the outdoor sensor (it only 'talks' with the thermo/hygro sensor).
This tests the heart of the whole system, that is, without the console/display to thermo/hygro link established
you won't get the rain or wind sensors to read either.
If it does seem to work like this then just be sure the rain gauge has good Alkaline batteries and press the reset on the wind sensor (if it isn't reading on the console already) and go through the 3 steps again to be back in operation.
Hope this helps and good luck.
