What we do
Three disciplines. One engineering bench.
From the silicon on the bench to the screen in your hand, Raywise builds the parts of an industrial system that other suppliers have to glue together.
Industrial Automation
Equipment, sensors, and the wiring between them. Spec, source, install, and commission from one team.
IoT & Software
Connected devices, firmware, cloud, and the apps that put it on a phone. From sensor to screen.
Mobile management apps
Manage on the move.
Every business line at Raywise ships with a companion app on the App Store and Google Play. Operate your systems, track shipments, browse components, and read live dashboards from a single tap.
- Smart-control scheduling & remote override
- Industrial equipment dashboards & alarms
- IoT device onboarding, telemetry & firmware
- Components catalogue, BOM share, datasheets
Apps integrate advertising and analytics SDKs as disclosed in our Privacy Policy.
9 apps
One app per business line.
