A few questions that occur to me:
Does the WMR200 console still see the sensors?
Is it possible that the WMR200 data logger buffer is full?
Are you sure the sensor batteries are okay?
Have you tried re-booting Meteohub?

Since I'm having, from time to time, rain sensor troubles, and the only option I found is reseting the WMR-200, which is not fun, I would like to know if:
- Have other users a better trick?
- Can Boris force a rain-sensor reseting in WMR-200, from meteohub?
For me the trouble occurs when there is a 'major' collision within WMR-200 data logger and meteohub, and I have these collisions always in minute 46, of any given hour.
The batteries are OK. And the WMR-200 datalogger is not definitely full.
Display in WMR-200 (for rain) shows '--' (hanged!)
TIA,

Is it definately a collision. i.e. does it never happen if you have the Meteohub disconnected?
I'm wondering if there is perhaps some other radio signal in the area that causes this.

How far between the console and rain gauge?
Are there any obstructions (at all) between the console and gauge, if so what are they made of?
Is it possible to at least temporarily move one or other devise to get them closer?
The rain gauge seems to be the weakest of the WMR200 sensors (or maybe it's that the others tend to be mounted higher). I used to get occasional drop outs from the rain gauge on my WMR200 console - moving the sensor only 0.5m closer solved that problem. Others have found moving the console away from radiation sources (e.g. WiFi equipment) has helped.

Most of the times problems don't come alone, it must be a sum of weaknessses.
I didn't change the location for months and it worked fine ( 4 months). Then I change it and suddenly it began to fail. Moved again to first place still fails from time to time (15 days OK last time).
I'm living in a countryside place, so not many radio signal around!
If distance, by its own, could be a problem, then always would fail.
That bothers me, because always happen when I'm far away from the station :dry:

Not if you are almost at the limit of the range.
If you are near the limit then some simple change[1] can make the difference between 'just works' and 'just does not work'. Before I made that 0.5m move the rain gauge would be fine for days and days, then drop the signal. In that case the console was connected to a PC (i.e. not Meteohub).
[1] e.g. maybe even something physical, such as it rains and there happens to be a tree or bush in the path of the signal.

The location now is exactly the same where it use to work fine for 4 months, or longer.
But I agree there must be a limit, so I'll give a try putting it closer... When I'm at home... Now I'm in a 'sort of' holidays...
Still, could it be a feature that allows user to reset the station ??? Or it's impossible to reset a sensor in WMR-200 from outside (Boris)?

I don't know of a way to initiate a sensor reset for the WMR-200 via usb connection. sorry.
