This is kind of an odd use for Home Assistant but i thought it was pretty slick. We have a command/dispatch vehicle that is used for emergency purposes and we wanted an easy way to monitor the status of onboard systems and provide local personnel with an at a glance status page . The vehicle has multiple cellular internet connections, workstations/IP phones, cameras and relies on systems available through a VPN tunnel. I am using a Strato Pi Touch Display Kit (RPi 4 with official screen) mounted in the vehicle equipment rack. The RPI runs rasbian with docker (and HA in docker mode). The Pi boots and launches HA in kiosk mode. I’m pulling elements from the pepwave cellular router via rest API and other network device availability via ICMP/SNMP. The dashboard is fairly large and basic with green good, yellow alert, and red bad. You can easily see Cell signal as well as availability of the other systems, you can also view vehicle cameras on the screen which is super slick. I pulled an image of the RPi SD card since i suspect it’ll probably die at some point but it only runs when the vehicle is on for (training, testing or in use).
