Some progress so far,
WiFiLogger IP found through Wojtek's expert help so CumulusMX, CWOP, PW Weather, WU, and HWS pws-wfl back updating.
Yawcam is connected, both Bloomskys ok again, Ripe and Sam Knows being monitored.
But still a few things to fix: Got Brother printer working by cable connection so still some work to do for wireless but I know the IP for it.
I'll need to contact my irrigation company to update Hydrawise.
So next is Blitzortung and Google box whatever that is!?!
If I recall correctly the Blitzortung was at 192.168.0.16 so I'll need to get into the settings somehow to change the IP for this in the same way as was needed for WiFiLogger.
I just hope I don't need to go through all of this again in a couple of weeks when we do the actual move to the new place.
Thanks to all that have commented and given suggestions
Enjoy,
Paul
