I have a relative that escapes our cold Canadian winters to enjoy the Florida sun.
While away, he is not using his e-Bike and motorcycle helmets, both have batteries. He read that they should be charged once a month…
Since he has a Hubitat hub, he added a power bar to a Zigbee plug. We created a Rule Machine rule that will turn on the plug every month on the first day of the month then turn it off on a 6-hour delay. His batteries are plugged on the power bar and get their fill every month, keeping the batteries in good shape.
One nice thing is that even if he decides to disable his internet while away, the charging continues!
