Installation
Connecting the smart meter
Connect the Dongle to the P1 connection of the smart meter via the supplied P1 cable.
Connect USB Adapter
In most cases, the dongle is powered via the p1 port of the smart meter. If you have older smart meter ( v2/v3 in NL ), a USB power supply + micro USB cable is necessary.
Every adapter is fine
The USB adapter may be an old smartphone or tablet adapter or a USB connection that is available in the meter cupboard (e.g. from a NAS/Router). Almost all USB adapters are suitable.
Connect RS485
See the Modbus RTU connections below. GND is in most cases not necessary.
Leds
There are two leds:
blue led: flash on at startup and flashes when a P1 message is successfully read
green led = power indication. Should always be on and NOT flashing.
Button
The button has several functions:
Press and hold during powerup = download mode
short press (< 5 sec) = reboot
long press (>5 sec) = factory reset. All values that are adjusted via the RS485 connection are reset to the default values
