looks good from this side, nothing obvious missing.
Does it make sense to upgrade to 2.5M2? M2 is based on the new build system with a lot of changes. M1 is more 2.4-like so running the binding’s 2.5 build on this version is not really a proper proof.
Please copy the log with the binding’s 2.5 build (use code fence, last icon in the icon bar when composing a message here, before the settings icon)
How can I make that log with the binding’s 2.5 build? also you propose to update to 2.5M2? which repo can I use?
2.5.0M2 is available here:
https://www.openhab.org/download/ (switch the selection from 2.4 stable to 2.5M2)
You should do a backup of you running environment.
@hmerk Do you know the timeline for M3?
When I want to update why I receive this error message?

This is your issue, you need to update your source list to fetch jfrog.
For 2.5 Milestone2 you need to switch to testing.
I updated to 2.5.0~S1669-1 and still not working… I still don’t see the shelly binding in bundle:list… What can I do?
Please try the build from the snapshot branch. I added various checks on initialization to narrow the problem and some more details on the bundle if activate() gets called.
Before installing the new build:
I did twice what you recommended above and nothing happened… Here is my log.
I followed also your installation description with the latest available binding.
But nothing showed up in openhab.log regarding shelly binding.
Floods are up and running 
Great job Markus 
just to make sure: you copied the binding jar to /addons ?
Do you have any other jar in that folder? Do they show up?
Which other bindings are installed?
this I have to /addons folder
What can I do?
I have a binding for one-wire in my addons folder and it is showing up. But not the binding for shelly.
Question/Feature request.
Sometimes it can be useful to work with visibility…do you think it could make sense to have a channel that shows if a device is reachable/working (e.g in mqtt we have LWT) ? Or it’s better to rely on the network binding and don’t reinvent the wheel?
Just brainstorming…
Thanks
This should be indicated by the Thing state (online/offline) and not via a seperate channel.
According to the design concept, a Binding should set Thing state to offline ( with additional information like config pending or communication error) when a device is not working properly or reachable.
Especially with battery operated devices, which will be in deep sleep mode most of the time, you will not have any valid monitoring if the device is working.
Yes it is indeed in PaperUI but I cannot show an item in sitemap based on Thing state…or can I?
Yes I understand it cannot be a monitor system for all types of device, I was just thinking about visibility to clean up a bit a crowded sitemap (e.g I have a bunch of smart plug but I don’t always use them all, some are dedicated to “temporary” setup and I don’t always want them around).
As I said: just brainstorming…maybe it was a silly question 
I can achieve the goal with network binding.
No need for the network Binding.
You can request Thing state in a rule and feed a virtual item with the state. This Item can be used for visibility.
This should be already the case:
The solution for you:
This is a rule, which I created for a similar purpose:
/* ---------- Monitor Pool Status ---------- */
rule "Pentair Controller offline"
when
Thing "network:servicedevice:c2e9cdf0" changed or
Thing "pentair:ip_bridge:de80dacd" changed or
Thing "pentair:controller:20ae54fa" changed or
Thing "pentair:intelliflo:f4c07d6a" changed
then
var message = "Status of Pentair equippment changed:\n"
var wifiOnline = ThingAction.getThingStatusInfo("network:servicedevice:c2e9cdf0").getStatus()
var bridgeOnline = ThingAction.getThingStatusInfo("pentair:ip_bridge:de80dacd").getStatus()
var controllerOnline = ThingAction.getThingStatusInfo("pentair:controller:20ae54fa").getStatus()
var pumpOnline = ThingAction.getThingStatusInfo("pentair:intelliflo:f4c07d6a").getStatus()
message = "Status WiFi adapter="+wifiOnline.toString() + "\nPentair Bridge="+bridgeOnline.toString()
message = message + "\nController="+controllerOnline.toString() + "\nPump="+pumpOnline.toString()
reportAlarm.apply(houseId, mailTo, "Pool equippment alarm!", message, mailFooter)
end
I’ve never thought about using Things’ state and rules, thanks I will sure look into it!
