Otherwise it could be an issue with the solar panel/supercap --where its not being used during the day and hence battery being used instead .. battery should only be used at night time really ..

So was gone Thursday and Friday and back Saturday However, both times temperature and humidity readings went way off, temperature went to exactly -67.8c both times and humidity to 100%. Completely dead now and not transmitting any data. I fear it is an issue with the solar panel/supercap, which doesn't seem easy to replace. It's outside the years warranty however consumer law should cover me.

I got in contact with Ryan Wilhour from Scaled Instruments:https://www.scaledinstruments.com/ and within a few hours he identified the problem, it was the 'SuperCap' as RKK suggested above.https://www.scaledinstruments.com/product/davis-7370-093-pro2-super-capacitor-supercap/ Pretty cheap, but given that my Davis (Pro 2) is over 10 years old, I just went ahead and purchased a new ISS transmitter:https://www.scaledinstruments.com/product/davis-7345-976-pcba-for-pro2-wireless-iss-or-iss-plus-us/ and temp/humidity thermometer, which were far cheaper than what I would have got them on either the Davis site or any other 3rd party sites. I don't know about the Vantage Vue as it does look like a more complex machine, but send Ryan an email (address at bottom of his webpage) and he will advise and point you in the right direction. Very helpful guy.

Davis support has been underwhelming so far, got an email reply after a week informing me that I have to ring them to organise a repair, they don't have an Irish number, but have a British and American number. Tried to call the British number, but they're only open 8am-4:30pm MON-THURS and 8am-1:30 on Friday, so they're fairly hard to find time to call. I'll ring when I get a chance. Working for the moment anyway, while there's relatively sunny conditions.

After much troubleshooting I've came to the conclusion that it's the common supercap issue, and when the battery is in the station that it won't use the solar panel and will simply just drain the battery.
