I think a few of us suffered from loss of data to our consoles. I am not sure what the issue is but suspect its the time of year, lack of sun and rain. Now in theory Davis will say that there equipment should work at all times but clearly its not.

Mine has just gone off again as the heavier rain has arrived.

The other theory is that the new Vaisala Unit maybe interfering with the signal

Please add your thoughts on here, thanks

Oddly enough my Davis has been fine for the last 3 days - famous last words!

I take it you've put in a new battery?

New batteries should work without solar input for up to 8 months.
Some possibilities - a drainage problem, poor transmittion (weak signal) or interference.

It shouldn't be weather related - how many times in past winter's have
we had gloomy days, and it works ok.

I still think the Vaisala has something to do with it, perhaps that big battery.

Worth contacting Matthew.

I do not have any Davis kit, just some Vaisala kit, which works happily alongside my other sensors. I too have lost some sensor data over the past few weeks, mostly individual sensors, and in particular the grass and concrete sensors (the latter is a Vaisala unit). These two seem to be stopping functioning due to the amount of water that has been coming down, rather than anything else. Indeed my Kipp and Zonen solar unit failed too and when I took the wires off my Labjack inside I had water coming out of the wiring, even though it has been sealed against rain for the past few years since its installation. So for me I would first consider the continuing dampness with not real drying out period as a strong possibility. I had also thought that there may be some high intensity radio transmission (HIRTA) in your area but none have been showing up on the NOTAMs to account for it.
The fact that they are almost occurring together does suggest some wider form of problem or one that is common to all, like the installation of the Vaisala unit at your stations, but I suspect with Vaisala's commitment to quality I would find that surprising.

I have a replacement VP2, brand new about 12 months ago ( will have to check guarantee) as my station is so far away from the house, I need a repeater. On installation it has been working fine until about 2 months ago, when low battery appeared on the console, now I dont know if this meant the Console battery ( mains connected) or the repeater battery ( again mains connected). I assumed it was the Davis unit outside so I replaced it, so the battery is less than two months old !!

I have heavy rain, high humidity and little wind and its gone off again

Also I have an older Davis Console connected to a Temp Probe which I use for a Grass Min reading from the house, that has also failed this morning.

I am still leaning towards just the weather, but it shouldn't really happen !!

Should I change the battery again !!

Did the problem (2 months go) coincide with Vaisala installation?

Change the console batteries - you never know.

It may have done, but I didnt really take much notice, just thought with darker days the battery had gone

Its been on and off all day now, currently showing as "Lost"

Will try another battery in the morning

If the console is plugged into the mains it should be OK, surely. My problem a few weeks ago when I unplugged my console to take it to the computer was that it immediately lost all current information so all the 'start up' stuff had to be inputted again when plugged in. The reason was an unseated battery (as Paul sugested). I also changed the console batteries for good luck!

With these very dark days I am expecting to have to change the outside battery any time soon. The never last more than a year, despite Davis's claims. However I have never had intermittent problems like those described above. I don't have all the fancy stuff which has just been replaced with such a palaver. I do feel for you having to get rid of your tried and trusted equipment. *whisper* I still have a mercury thermometer!!

Thats Shocking Anne - will send around the Mercury Police !!

AWS was working OK late evening, but off again now with the fog

I am still in two minds whether to change the battery or not, or see how it goes withe better sunnier weather on the way ?

Battery changed but no joy
Battery checked at local shop, was fully charged

Unfortunately it wasn't a rechargeable battery I was using but should have been working anyway

So it looks like its something else ?

I do have a repeater system, which makes it trickier for me to diagnose . Will have to cancel repeat first and take console up to the station to see if I can find a signal. Time to get the reference books out, all in all very annoying.

Carl- can you let me know the source of your battery replacement please, thanks

What about other interfernce e.g. from wi-fi, cordless phones or as I've found out this week, one of my tablets loses internet connection in the kitched when the microwave is on.
