mDNS discovery finds my AP:s, Sonos system and Neatmo but not P1 dongle. Sonos and Netatmo still works with Homey.
Nothing changed, I have also checked router logs.
And Energy app works fine.
Well if you can’t see the P1 in that app, then Homey can’t find it either.
Try to powercycle the P1 (again, yes I know) maybe for a 1 minute to be sure it has no power via usb and/or your smart meter connector. When you power up see if it starts to show up in that mDNS browser app again, only then it will work with Homey.
How can i Get the voltage readings in to Homey ? Have the 3 phase meter: SDM630
Unfortunately it did not work out.
Ok what kind of router do you have?
I need to add that to the code.
Ubiquity UDM
My P1 stopped working just at the same time 11 CET.
Mine is connected to Ubiquity UDM Pro
Mine is not, have an opnsense router with Unifi accesspoints.
I have checked my router settings and there are no broadcasting restrictions activated.
So mDNS not working makes finding it hard for Homey.
See if you can make the old ip static for the P1 what it was (click on red marker in P1 it will throw error and ip address). Reserve that address in your UDM and it should get back up in Homey.
Raised a support ticket with Homeward but don’t expect a solution soon.
Click on red triangle only tells it is not available.
I looked into the routers disconnected devices and found the “old” device. I can not see old ip but what is confusing me is that the “new” P1 and old P1 have different MAC. How is that possible?
That must be the reason that the leased IP not is working.
They stopped the current rollout for this firmware 5.04. Cant tell more for now as they have to investigate.
Ok, thank you for the update.
I found out the old IP and changed it but it did not make any difference in Homey.
Then I am out of options as well. Downside of test/beta firmware P1 user.
Got the same problem (no mdns traffic from P1).
At least homewizard dev team is made aware.
It would be great if you could find the time and energy to do that 
,will send some money
Oh I will, thx a lot for your paypal donation.
