[WMR 200] th0 loses connection

[Vetinari]

Hey all,

strange behavior from the outdoor temperature sensor:

Nearly every day on 05:44 a.m. or 11:44 a.m. the sensor loses the connection.
For me it seems so regular, that this cannot be only a random lose of connection.
Anyone have similar problems? Or any solutions?

Oddly, I have experienced the same problem with my WMR88 connected to iconnect running Meteohub 4.9k. At 05:44 every day over the last three days I get message that data has not been received for 30 minutes, uploading has stopped and all sensors show 'never'.

Reboot of meteohub cures problem and all is well until 05:44 next morning.

I am running meteohub on sheevaplug with meteohub 4.9e.
But perhaps it is not only the sensor?! Can meteohub interfere in some way, i.e. a cron job or something that could cause the disconnection?

Here are some new data:

In March or May I changed the batteries but at that time all seemed fine. I will check the batteries once again.
Luckily only the th0 sensor is affected and I do not have to reboot. After some time the connection of the sensor is established again or I have to manually search by using the WMR-200 central station.
@wochips, you do not have a solution until now, do you?

RF conditions of WMR 200 are not the best. try relocating sensor or console.

I previously had a problem with dropped sensors for 30 minutes causing the upload to shut down but after changing to a much shorter usb cable than the one supplied with WMR88 the problem went away. The problem returned for three days failing at 05:44 each day with nothing in my set-up being moved or changed, however, today there was no problem.

I do lose the th0 sensor once or twice a day but these losses are temporary and only cause the occasional loss of one upload so are not a problem.
