I have project idea to use Smartthings as a Caravan security system. My Caravan has a crap alarm and is not really fit for purpose but a replacement would be a similar cost to a basic Smartthings integration.
So what I’m looking at is installing a hub and mifi with a ethernet switch into the caravan, using the existing 12v solar power as a power source.
Adding a motion, flood, and door sensors use an old android device as a geofence presence device. via wifi
I can see that all the main elements are available and should work together. But I’d be interested in other opinions on this especially the following elements.
- Stability of a mifi (4G) connection over extended periods
- Running ST Hub from a 12v battery source.
- Using old android devices for GPS location long term.
- Data usage of the hub with 4-5 sensors
I’m probably going to try it anyway but I’d be interested in what others think about the idea
