My Yarbo is currently working fine, in spite of this issue, but I have noticed that my Data Center is constantly going Online and Offline. You can see from the Domotz screenshot, it has cycled 228 times in the last 24 hours. Any idea why this is happening?
Are you blocking any ports/protocols/IP ranges, etc? Is the DC negotiating at 100Mbps and is your switch capable of supporting that speed (some won’t go that low)?
Hi there, could you please check the Ethernet cable connected to the data center and the router? Try unplugging and replugging the cables to see if this resolves the issue.
If that doesn’t help, please submit a support ticket so our support team can investigate the issue further.

I have tried unplugging and replugging in the cables to the Yarbo PoE Power Adapter and to my dedicated PoE Switch (Lulu XMS-1010P) with the same result. I am able to do a cable check when it’s plugged into the PoE Switch. The results are below:
Obviously, it’s concerning that Pair C and D are reading as disconnected. I tested the cable before installing and it passed. So I’m not sure what changed. Unfortunately, my Data Center is mounted on my roof and we have about 3 feet of snow. So I’m not excited about getting on the roof to replace the ethernet cable or paying my guy $250 to do it.
Maybe someone with network expertise can explain why Pair C and D being disconnected would cause this behavior?
Thanks, Bryan.
So if I’m understanding correctly, the Pair C and D being “disconnected” is not a problem with the ethernet cable, but because the Data Center isn’t using those wires (being a 10/100Mbps system)?
I’m going to assume that the switch is calling the pairs like this:
Pair=Wires
A=1,2
B=3,4
C=5,6
D=7,8
For standard ethernet you can see that it uses wires 1,2 and 3,6. Therefore for communications it is using wires from pairs A, B, and C. I would look for corrosion and maybe it’s just a bad crimp on one side of the cable. Cutting and re-crimping new connectors on both sides of the cable might fix the issue if it is bad on one side. Obviously one of those are on the roof, so that’s a problem. If you have an ethernet wire tester, it would show whether or not if there’s an open on the pairs in question. From the sounds of it, there is an intermittent connection on pair C that is causing you issues, at least if I am understanding the situation correctly. It’s odd that it isn’t impacting the POE power.
Hi there, as our support team responded in your support ticket:
The Data Center automatically chooses between two RTK communication paths—NTRIP and HaLow—to maintain positioning accuracy. When the HaLow signal weakens, the system switches to the back-end tunnel and actively pings your router to stabilize the connection. The online/offline toggling you’ve observed is part of this normal tunnel maintenance behavior and does not indicate a malfunction.
