Software:

The Gelidus Research mmWave sensor is designed to run on ESPHome frameworks. ESPHome integration with Home Assistant (HA) is ideal for providing a rich user interface. Adding the GRPS1.AC to ESPHome and HA is easy using the preinstalled captive portal. Using any tablet or phone that identifies a captive portal you can link up the module without any serial firmware programming hassle’s. Once connected to your WIFI network you can interface to HA using one of the provided install guides.

Safety:

Never operate the  Gelidus Research AC powered mmWave sensor board without a protective enclosure, it will expose dangerous potential contact with your AC mains supply. We can supply a safety enclosure or you can download our 3D printable STL files for DIY projects.
