For coverage, do you have the ability to put a router half way between the buildings? You’ll need 5v snd a little shelter. Maybe you have an external lamp that you could put a zigbee bulb in?
No I don’t there is just lawns, trees and vege garden between…no power. The outdoor lights are on studio and house itself
I would be a bit worried about range at 50m.
Why not run 2 coordinators, and 2 instances of z2m, one inside (say a pi) and one in the studio.
I was not sure that I could…but it sounds like I can 
Now just need to work out which Coordinator to purchase
@tube0013 just wanted to say thank you for your coordinators and router I got recently, they look to be working great! Thanks for your effort and making these available to the community.

Out of nowhere my zigbee2mqtt went down. I’m getting this error in the logs:

Any thoughts?
check that the coordinator is reachable in a browser.
did you recently update z2m?
It is reachable by browser. Updated z2m a few days ago and network was working at that time and suddenly died today
Have you gone to the link you posted in the log?
I have, wasn’t super helpful
ip still the same? (and z2m is configured to go to the ip)?
No change in IP and config in z2m still points to the same ip
pull the power on the coordinator for a few minutes then try again.
Will try and report back
feel free to PM me too.
when you power it back on, let it come up and then hit the web page of the coordinator, watch the debug log while z2m starts to see if it ever even attempts to connect to the coordinator.

get that over and over on coordinator
I’m going to PM you some options.
I’m using CC2652P2 Based Zigbee to Ethernet Coordinator, understand the hardware is capable of outputing 20 dBm power but does the z stack firmware also configure to output 20dBm power?
