Domoticz

Hello.
Have one ZMNHDD1 the kitchen. Struggled to get it included it in Domoticz, but after a bit I found out that i needed to use "Include Node Secure" to include it, has gradually worked somewhat unstable until it eventually operated stably (stale for weeks now).

Installed yesterday two new of these modules, one in the hallway and one in the bathroom, both I struggled to get into domoticz, but eventually it seemed that I got the one in the hallway included, this time with "Include Node".
Worked unstable in the start, but pretty soon it worked more stable.
 
But the bathroom I struggle with.
It is "Dead" and always "Dead", unable to revive it, have tried healing of the entire network, and only node, rebooted server, enabled polling, but it does not help.
 
Running UZB1 stick Version: 1.4-235-gd9eb0ff
Domoticz Version: 3.5110 | Build Hash: 6377226 | Compile Date: 2016-05-03 6:22:21 p.m.
 
any help?
(bout the one in the hallway and the one in the bathroom are on the same fuse)
Attached some pics:

-removed the fuse
- Waited a while
- turned on "include node secure"
- screw in the fuse again
- Waited a bit, eventually it was included, now that new node, "node22" instead "node21"
- Sitting in 2 equal power meter devices then, probably both from node22, but also with a working switch
