  1. Great Product 5 Star Review

    Posted by on 22nd Aug 2019

    Timely delivery. Easy installation. Ready access to weather station data on iPhone and laptop. Would recommend this product.

  2. It Works. 5 Star Review

    Posted by on 15th Aug 2018

    Prompt delivery, article as described, and working well. Already survived a serious storm.
    Generating interest amongst friends and others, having an internet connection. Also opens up a new field of interest by being able to look closer to what goes on in the subject of weather much further than the confines of my home property.

  3. Outstanding product support and service 5 Star Review

    Posted by on 24th Jan 2018

    I have had the Weather Sleuth for 12 months now and it delivers amazing data. Coupled with the wunderground.com website offers truly professional local and global weather information.
    I recently had a problem with the hardware which was tricky and time-consuming to identify and resolve. Monax were outstanding and in the end replaced the entire unit. Thanks for the great product and support.

  4. Easy as 5 Star Review 5 Star Review

    Posted by on 26th Jun 2017

    I know very little about computers. It was extremely easy to put together & I followed step by step instructions & it worked!!! over the moon with it. Love it highly recommended.

  5. Does exactly what it says on the tin! 4 Star Review

    Posted by on 14th Jun 2017

    We got this weather station about 6 months ago and it has been great. Easy to set up, accurate weather recording instantly uploaded to the web. We did have a failure after about 3 months but Monax were great and sent out a replacement very promptly. It gives me the confidence to recommend Monax to anyone looking for a weather station. Great service.

  6. Accurate, reliable and easy to set up! 5 Star Review

    Posted by on 11th Feb 2017

    What a brilliant weather station! I've been tracking my readings against some reliable weather stations (not Netatmo) nearby and it's spot on. Measures, rainfall, temperature, humidity, wind speed and direction, pressure - basically everything you need. It's a shame Weather Underground allows the Netatmo weather stations on their network because nearly all of them are extremely inaccurate and are useless.

  7. Great station and fantastic customer service 5 Star Review

    Posted by on 11th Jan 2017

    Received a WeatherSleuth station for Christmas and is a great little unit that is dead easy to setup and is accurate out of the box with only minor tinkering. Highly recommend if your budget does not extend to a Davis. I did have some problems with the pressure sensor that gave inaccurate readings, but Monax replaced the entire sensor sensor suite, no questions asked. Arrived two days later and now works brilliantly. Highly recommend going through Monax, fantastic customer service.

  8. Great for a Novice, Needs a MAC IP finder tool though. 5 Star Review

    Posted by on 2nd Jan 2017

    I was looking for a PWS that didn't include a console (how many consoles do you need?) and this one came up. It was super easy to install out of the box and configure and it was set up to automatically connect to the Weather Underground. There are only 2 things to be careful with. Firstly for Southern Hemisphere users the orientation needs to be adjusted as the compass indicators on the unit reflect a Northern Hemisphere. The receiver also needs to be set up as well - the manual notes this but it would be easy to miss. The second thing to note is that the s/w tool supplied works for Windows devices only and I have a Mac. Luckily I had an IP scanner on my MAC so could find the IP address of the receiver. All in all a great unit and would definitely recommend it.

  9. Fantastic 5 Star Review

    Posted by on 9th Sep 2016

    Very quick and simple to setup. I was pleasantly surprised to see the amount of standard features this station has to offer. Living in the tropics weather is a big talking point, and there is nothing worse than been given information from our local weather station 25kms away.

    Having young kids who love to be outside playing in the tropics has always been a problem, now that we have an accurate UV reading we can now be more at ease when we allowed them outside.

    I wouldn’t have a problem recommending this product to family and friends.

  10. ip set up easy 5 Star Review

    Posted by on 1st Sep 2016

    The station worked out of the box after fitting batteries and wind vane. IPtool run on computer identified the iP sender, followed comprehensive instructions. and it all worked beautifully. Wetaher cooperated by being windy and rain the next day.
