I run a Healthcare IoT startup and after 8 months of development, I’ve finally begun to sign enterprise contracts.
Currently, we leverage Raspberry Pi 4B’s (AARCH64) as the IoT Gateway for our ZigBee 3.0 devices (“sensor kits”). These have worked beautifully for our pilot users where it is 1:1 gateway to “sensor kit” ratio but in our enterprise deployments (assisted living facilities, memory care facilitites), we will be looking at a 1:20 gateway to “sensor kits” ratio. The applications that run on the edge are fairly simple (Zigbee2MQTT, Node-Red, MQTT and a few low-cost Python containers) but there will be an increase of 20x traffic.
I am curious for those who have made the jump to commercial deployments, is it still feasible to leverage Raspberry Pi 4B for commercial deployments? If so, how have you dealt with high-availability in the event that the board blows out or SD card gets fried? Have you left the RBPI ecosystem altogether and now rely on NVIDIA, INTEL or GOOGLE AARCH64 hardware? Coming from the RBPI world, how friendly are these ecosystems?
Would love to hear any experiences that ya’ll might have had!
