# Remote control
|
|
|
|
The device listenes for remote control commands on LoRaWAN Port 2. Multiple commands per downlink are possible by concatenating them, but must not exceed a maximum of 10 bytes per downlink.
|
|
|
|
Note: settings can be stored in NVRAM to make them persistant (reloaded during device startup / restart). To store settings, use command `0x21`.
|
|
|
|
Send for example `83` `86` as Downlink on Port 2 to get battery status and time/date from the device.
