Done and dusted, both Consoles updated.
Success!!!! All seems fixed now, the lightning sensor has appeared already on Ecowitt for the missing console, and the battery status has reappeared on both with an additional entry.
Thanks very much for that... wouldn't have figured that one out myself at all.
Will let them tick away now for the next few days and the next step will be re-site the outdoor sensor to a better, turbulence free spot away from the house, and order a WH45. Expect more questions
Thanks again!!
