We recently upgraded to a new home in Fernandina.
I believe we are the third owners for this home, not sure about previous owners.
In the cabinet for the sprinkler controller there is another item - "Cyber Power".
This appears to be a battery backup for something.
In checking on Google it looks like it is to backup maybe for cable or WIFI, but not sure??
The Indicator on the unit has a red light that seems to show the battery needs replacing.
In checking the battery replacement cost it looks to be about $25. so, not that much.
My question is what does this unit actually back up, and is it really needed?
We deleted cable and now have only WIFI through Comcast/Exfinity, and stream thru Roku and U tube TV. Have not had any problems with any of those, so far.
Does anyone have any information about this "Cyber Power"?
Thanks in advance.
