Datalogger for wmr928

I have a skyview datalogger to go with my wmr928/918 and have had several goes over time at getting it to work with WD but it seems to fall at the first hurdle.

First the logger was setup with the settings shown, with the software that came with the logger
I click on get status and it gets raw data but does not give me the status as can be seen above and i left it going for 30 min.
Switching the new logger type switch on made no difference
I also note during this 30 min that WD got no data so graphs have flat lined on the right

i take it nobody has one of these dataloggers looks like i’ll have to get larger battereies for my UPS’s
logger does not hold enough data at 1 min interval about 30 hours for me, 7 day would be better
