Problem(s) Encountered:

 ...around 21:45, all of the OSMOS monitors (all 6 - including the weather one) started to turn and off. The connection to the 2.4m telescope was not lost but the screens were hardly on long enough for us to control it for the night. In other words, every monitor would turn on and off at the same time every few seconds/minutes coincidentally (not sarcasm) after the generator kicked on.

Solution:

The desktop UPS for those monitors had failed.  Replaced batteries in the unit.
