Homey Pro
Install the SENSY-ONE app and add SENSY-ONE → E1 Pro in Homey. Connect the sensor and Homey Pro to the same local network, then select the automatically discovered sensor in Homey.
Use measurements and presence in Flows and Insights. Open the SENSY-ONE app settings to draw three detection zones and one exclusion zone, view live targets and save your changes.
The app is currently under review and is available through the test link above.
Home Assistant
Use the SENSY-ONE Zone Editor for floorplans, live 2D and 3D target views, heatmaps and zone configuration.
