Can’t link a node to gateway

The most common reason of this problem is that the node is already linked to another gateway and must be unlinked or reset before it can be linked to another gateway.

If you know which gateway it is linked to, you can simply place it near that gateway so it will pop up in the “Devices” menu after a whileand then unlink it.

The other option is to perform factory reset of the node.

In case of NWIN002, NWIN004 or NWIN005 (Pt100, 4-20mA or 0-10V) you can do a long-press on the small side mounted switch next to the LED. A long-press does a factory-reset, so node will become unlinked and return to the default 1-minute transmission interval.

For NWIN001 or NWIN003 it is a little bit trickier to reset, as you must short two pads on the radio PCB, labeled “RST”. The sensor will detect the short when it wakes up for the next transmission. To speed this up, it is suggested to remove the batteries, wait 30 seconds (to drain capacitors), and then reinsert the batteries before shorting the pads.

In both cases if the factory reset was successfull, the LED will start blinking rapidly, showing the node is in an unlinked state.
