My Shelly Pro 3EM is on - as of today - latest firmware version: 1.7.0 - 6d4afb10.
The high-level problem is, that it's rarely being disovered by mDNS/DNS-SD scans, whereas all the other devices, incl. shellys (though all of them gen1), are being discovered reliably.
Technically it appears, that the Shelly Pro 3EM does not react to scans, nor does it periodically (at least not in reasonable intervals) send out DNS-SD advertisements.
It does at startup (so I can trigger that by rebooting) and also when changing settings (e.g. toggling eco-mode (doesn't matter whether from off to on or vice versa)).
While I can't swear on whether it have been working (better) before, this feels like a regression. At least the PRO compared the predecessor (Shelly 3EM gen1).
Scans initiated via `avahi-browse` (other implementations I tried didn't make a difference) - all devices in the same network-segment without any firewall / wifi client isolation rules.
