Weather recording equipment

From 2006 until the end of 2015 I was using a Lacross WS2300 weatherstation. This station could work with a wired connection or wirelessly. It had performed reasonably for 9 years but had some reliability issues with the wind sensor and timestamp issues with the base unit. After several replacement sensors and a new Thermo unit I decided to replace it at the end of 2015. I bought a replacement weather station and changed over at the start of 2016.

The new weather station was a Gadget N96GY supplied by Maplins.This was a chinese unit made by Fine Offset and sold by many companies and re-badged accordingly. This unit could only work wirelessly between the sensors and the base unit. Readings were sent from the sensors to the base unit every 48 seconds. At the beginning of 2023 the sensor unit began misbehaving, especially the temperature and humidity readings. Maplins no longer stocked spares and I read online that Fine Offset had changed the transmission protocols so If I bought a new unit it might not work with my old base station anyway. In January 2023 I bought a new weatherstation.

The new weather station is a Aercus WS2085 supplied by Green Frog Scientific.This is another unit made by Fine Offset and sold by many companies and re-badged accordingly. This unit can only work wirelessly between the sensors and the base unit. Readings are sent from the sensors to the base unit every 48 seconds. The data is transferred from the basestation to a PC via a USB connection and can be displayed using third party software such as Easyweather or other commercial software that supports Fine Offset stations. I am using a program called Cumulus created by www.Sandaysoft.com.

Where is Mynydd Llandegai

Mynydd Llandegai is in the county of Gwynedd in North Wales just outside the Snowdonia National Park. We are about 1000ft above sea level. We have a clear view down to the sea to the NorthEast but all other directions are protected from the worst of the weather by mountains. This does mean however that we are in a bit of a frost hollow. The prevailing weather comes in from the south. The mountains to the south of us help to reduce the ferocity of storm winds and probably reduces our rainfall slightly. Having lived on the other side of these mountains and received the full force of the southerly gales in the past we can appreciate the difference it makes.

Weather webcam

The camera usually looks East towards Bethesda and the summit's of Carnedd Llewelyn & Foel Grach beyond. Sometimes it may be looking in another direction if I think there's something worth seeing. Images are captured 24 hours a day and updated every 5 minutes, though you won't see much at night time except a few specks of light from distant street lights. The camera points into the rising morning sun so lens flare can be a problem first thing. You can click on the picture to open a window with an enlarged view.

Having problems viewing

The weather data displayed above is captured by the publishing software and uploaded to my website every 5 minutes.The image has the same filename each time so it overwrites the old image. If your browser is set to cache images ( as most are to speed things up ) then the weather data will not update locally on your PC unless you refresh or clear your cache. Depending on your settings and what browser you are using you may only need to do a refresh. If that doesn't work try changing your browser settings to make it check for newer versions of stored pages each time it is started.

These pages are optimised for viewing on a computer using popular web browsers. They should also work on most phones and tablets but you may get problems on smaller screen sizes.
