The Aercus Instruments WeatherSleuth is at the leading edge of console-free direct to internet weather stations.

The Aercus Instruments WeatherSleuth is an Internet Protocol (IP) based weather station that foregoes the need for a console and instead bursts the station's data directly up to Wunderground.com; the world's largest and most popular weather station network. The WeatherSleuth's receiver module connects directly to your modem/router providing real-time internet monitoring from anywhere on any internet capable device (note: the receiver module plugs directly into your modem/router so your PC or Mac does not need to remain on).

The WeatherSleuth's all-in-one external sensor suite tracks the full range of weather variables including UV Index and Light and its rapid 16 second update places it at the forefront of modern weather station technology.  All major parameters are calibratable.

The WeatherSleuth is simple to install and is PC and Mac compatible.  Installation kit included.

  1. Good choice 4 Star Review

    Posted by on 10th Jan 2018

    I replaced an 3 year old Aercus WS3083 with this model - everything seems to work a bit better than the old system. I always viewed my weather results from PC or pad so a console was redundant.
    Two minor downsides -
    The ethernet cable I'm using keeps dropping out - might be a poor connection into the receiver.
    Wunderground have an all singing/all dancing app for iPad but not for Android.
    Big test is longevity of the sensors - but there is no way I can predict that after a month.

  2. Exceeds expectations 4 Star Review

    Posted by on 9th Nov 2017

    The weathersleuth was delivered very rapidly, and was quite easy to install. The biggest problem was locating a suitable open spot in the garden to install it. You need to find a post ( I used a 1 inch diameter metal tube which I attached to our pergola) to attach the main external sensor ( ext temp/ rain/wind direction & speed /sun/uv/humidity) assembly. The internal sensor (pressure/ internal temperature/humidity) can easily be attached to an internal wall (or left loose).

    The tiny receiver needs to be located near to a power socket, and is connected via an ethernet cable to your router. The instructions to download a small application from the vendor website to my Windows 10 PC and then configure the receiver worked first time. You need to set up an account on Weather Underground (free) so that the receiver can upload your sensor data in real time. It is straightforward.

    Your data can be viewed in two ways: on your local network you can use your browser to view the receiver IP address and see all sensors, together with battery status of the internal and external sensors. However this does not record historical data.

    The Weather Underground website collects all your data, which can be viewed by day, week, month ( chart or table) and downloaded. It is really quite impressive. The Weather Underground site took a few hours to start displaying my data, but is updated in real time after that. You can see your data from anywhere you can connect to the Internet. There is also a weather underground app for android and Apple, and my only gripe is that there is an additional app for Apple, which apparently provides extra functionality.

    So far, it exceeds my expectations.

  3. Highly recommended 5 Star Review

    Posted by on 19th Jul 2017

    I chose it as a more affordable option over the Davis stations. Set up was easy and connections have been solid since installation. Instead of using a weather underground account I sent the data to a home server running weewx. This too was easy to set up and has plenty of configuration options.
    Greenfrog service and delivery was great too.

  4. So far faultless. 5 Star Review

    Posted by on 1st Apr 2016

    I was after a Weather Station for our school, but the high end stuff didn't fit with our budget, so I looked around and found Greenfrog's range.

    I liked the Weather Sleuth because it offered better value ( since I didn't need the display screen) than the Professional Weather Station.

    Having chosen, I ordered and received in about a week, a nicely padded box of goodies.

    The instructions are clear and, for me, everything went together without issue, everything connected correctly and so it was time to mount the sensors on a pole on the roof. That done and aligned it was time to do the internet part. The signals will travel through 5 walls but not 6 :) The receiver has no problems receiving signals through a roof and 2 walls.

    I had created an account at Wunderground, put some details into the tiny blue box (It's about the size of a packet of cigarettes, if that) via the internet.
    It connected immediately, but took a an hour or more to be shown as a presence on the Wunderground site. All of this was to plan and explained either in the manual or on the Wunderground site.

    So, I can recommend this product, I can't comment on it's use with anything other than Wunderground, which is rather nice though.
