My Z-Wave network acted up again today.
Was able to ‘sneak’ past a sensor without any lights turning on. Hitting a Z-Wave wall switch. Took 10s for the Zigbee lights to go off, Z-Wave lights in group stayed on.
Using my z-wave sniffer I immediately noticed 2 nodes spewing out messages completely swamping the network. Power-cycled them; sniffer logs calmed down and wall switch worked fine again.
Nodes that acted up this time was (differs) : ZW096 Smart Switch 6 & HEATIT Z-RELAY Multipurpose relay
