Z2M pairing multiple devices at once

Hi.
I moved over almost all my Zigbee devices from a Conbee/Phoscon setup to Skyconnect/Z2M/HA.
The only devices left over are 3x GU10 Paulmann bulbs. Problem is: They are on a single power supply (on a 230V rail), built into the ceiling over the staircase in 4m height.
To get there I would need a ladder with individually adjustable feet. Which I do not have.

I can put them into pairing mode by tripping the breaker (5x on/off), and they will all simultanioulsy dimm up/down to show their readiness to pair. For 10 seconds. And then be full on.

But they will NEVER show up in my new Z2M (set to pairing mode).

When I re-activate my old conbee/phoscon box/coordinator, they are still available in the old network. Their settings never got erased.

My theory:
Is it possible that despite being reset (and thus set to “re-pair”) they recognize their peers next to them, recognize the Zigbee network ID of those peers as “known” and default to their previous network instead of reaching out to the new coordinator?

If so:
What chances do I have short of calling a craftsman with a special ladder?
As said: since they are on the same rail, I have no chance to power cycle them individually.

Any suggestions?
I’m a bit out of ideas: I fell off a ladder just one week ago and earned myself a broken rib, no intention to start new adventures with ladders especially in such a scenario.
Thanks for your ideas!

Scratch that, problem solved:

My last desperate attempt was to set up a Zigbee repeater really close to the lights…
And that did the trick.

I have seen this before, Skyconnect seems to be really picky regarding joining of devices that are further away than 5m.

Now they all joined and I’m VERY relieved I donÄt need to perform ladder-art.

N8 you all!
