I appear to have a problem with my Davis VP2 at the moment, last week the console stopped receiving data for short periods. Due to distance away from the weather station I have repeater station. Since the installation of the repeater loss of data has been minimal, but recently the console has been showing blank for 15 mins at a time.

On Friday, the VP2 was cleaned and replacement battery installed in the transmitting unit, at first it didnt work, but after fiddling with the battery a little it started working. Since then I thought it was going to be Ok, but I have now had several short spells with data being received, about 10-15mins at a time. Overall I and not to concerned with a few mins data loss here and there but as we approach winter, I dont want to miss out on any decent wind gusts etc that may be lost or the rare occasion where I may have an air frost.

The only think left for me to do is to change the battery in the repeater station, but this is mains power running out of the greenhouse, usually I get an alert if the battery is low on this device, but no signal received.

Solar panel - I have notice that my solar panel on the VP2 is stained and may not be producing much power, but the battery installed should overcome this issue ?

Just wondering what's up with it, is the VP2 transmitting about to fail or something else.

If anyone has any suggestions please let me know - don't really fancy forking out several hundred pounds for a fresh unit

thanks

(off again as I type, but back on as I finished the text)

You've probably done all of this, but:

''...but after fiddling with the battery a little it started working..''
Have you checked for corrosion in the transmitter box where the battery is placed?
Is it a brand new battery?

Sure someone will have a better idea.

Thanks

I didnt check specially for corrosion, but looked OK, old battery was clean

Ok this evening, so far , fingers crossed

Intermittent errors are always more troublesome than complete failures

My Intermittent data loss failure has continued. Looses the data for 30mins at at a time for no apparent reason.

Its off again now

Not much more that I can try, may be the end of some component ?

Possible ISS unit failure
