Query and displays
Various telemetry sensors and remote switches can be connected to LoRa hardware. The values determined can be displayed in different ways.
- Via serial console with the command -wx the following values are shown
- TEMP: 0.0 °C
- TOUT: 0.0 °C
- HUM: 0.0 %rH
- QFE: 0.0 hPa
- QNH: 0.0 hPa
- ALT asl: 0 m
- GAS: 0.0 kOhm
- eCO2: 0 ppm
- Via WEBService
- Via SmartPhone APP. The activated or existing sensors are also displayed in addition to the values.
- Via APRS.FI dashboard. The telemetry values are transmitted from the node via LoRa and when they arrive at the MeshCom server, they are transmitted to the APRS.FI dashboard in APRS telemetry format.
- The APRS telemetry format can only display 5 measured values per callsign and SSID (OE1KBC-20, OE1KBC-21, ...) in terms of value and also graphically. For this reason, the values are grouped according to the available telemetry sensors.
