I've got a new fan motor to install in the indoor unit. It's been making noise like it was going to die soon. For a few years now!
In order to make the new motor last longer, I wanted to hack the indoor unit,
and somehow turn off the fan motor, when the system was in idle mode.
Then, I looked for an easier method of shutting down the system,
and avoiding that 24-7-365ish fan motor, slowly burning it's bearings..
Now trying the Sensibo. It seems to work pretty well for over-night use.
I'm trying to get the best sensor location and temperature limits worked out.

My offspring's family moved to a new home that has oil heat upstairs,
and a nice 12k mini-split in the basement. (TV room / rec room).
They are also trying a Sensibo to control the minimum heat in the basement.
Since their new model Mini-split has the same old indoor fan more running, until the system has been turned off.
I'm not sure if they will even need to have the M/S on, since the oil burner's waste heat keeps it nice down there..
However, once we get down in the single digits for a few days..
That Sensibo might come in very handy..
