I bought 2 of the Greenwave $19.99 6-outlet powerstrips, because cheap and individual outlet control. They are working well with the driver "Greenwave PowerNode 6" (copycat73).
But they flash green - the manual says
"Two flashing green bars on each side of white flashing center: PowerNode cannot communicate with Gateway. This may occur if the PowerNode is out of range from the Gateway. You can move the PowerNode closer to the Gateway to improve reception."
This is a tiny house... the two power strips are about 8 feet and 14 feet from the Hubitat hub, nothing but wood and wallboard between the hub and the power strips.
If I do a "refresh" from the Hubitat device page for any of the outlets, the energy value updates, the "lastupdate" timestamp updates to "now", and I can flip outlets on and off at whim.
Any of these operations stops the green blinking, but eventually, they go back to blinking again.
So, why does the powerstrip think it has lost Z-Wave communications with the hub, if the hub can communicate with the power strip? If I leave things alone, both power strips will, after a few hours, start with the same green blinking again.
Yes, I can just ignore it, but I am concerned that I don't understand something basic here, and I am new to Hubitat, relatively new to Z-Wave devices in general, and I had HOPED that these things would help improve the Z-Wave "mesh", given that they are 120-Volt powered devices, not battery-powered like the deadbolts.
