Both are on the same Wunderground account, one now showing red circle against station name for not sending data for last 3 days, but the newest one has green circle and is sending data. Both still sending to CWOP.
Not sure if having two separate stations on one account is the problem......sent that question to Wunderground tech support, but no reply.
The fact that original PWS stopped sending data within minutes of the new one starting up is suspicious.
Both have different station IDs, and on weewx.conf they have different passwords.
