I'm rebuilding my father-in-law's complete weather system (5 years worn). The base station is an RS 63-1016. So far have cleaned up and reinstalled just the Outdoor thermo/hydro. Works great, connects to base. Also connected base to PC and am sending info to wunderground OK.
Couldn't find his indoor thermo/hydro/baro so went to OS online and bought a BTHR918 a 433MHz unit. Powered it up w/new batteries, all values look good, sendor button glows red every 30 seconds, stared scan w/base, base is not finding/reading the new indoor unit from 2' away. Reset base, started scan w/ "Channel" button, still not finding indoor unit.
Any ideas on what else to try???
