Maplin Wireless Weather Station (N25FR) Review

by GFR2

I’ve had this unit installed and running for approx. 8 months now, even though I’ve had it for nearly 18 months.  There is a simple reason for this, its my 3rd unit!

Why a weather station? Yes I know I could simply look outside but that wouldn’t tell me the actual temperature, how windy it really is, how much its rained or what the pressure is.

Whats in the box?

A rebranded Ambient WS-1050 weather station, which is handy to know as their instruction manual is much better! The kit comprises of

  • Indoor Base unit.
  • External temperature sensor, pressure gauge & battery box.
  • External rain gauge.
  • External Wind speed sensor.
  • Mounting poles, arms, brackets, screws, nuts, bolts and cable ties.
  • Instruction manual. ws1050

First Impressions.

Plastic, lots and lots of plastic and 2 very thin metal poles.  The parts feel like they want to break and need gentle handling, but they are meant for outdoor use so should be designed for all types of weather.

The base unit, also plastic but it looks well laid out with a main display screen and only 5 buttons. (Reset is on the back).  I would never have paid the full price of £59.99 for this but £24.99 was OK.

Install & Use.

As I said, it feels cheap so I was expecting the worst when installing – shockingly it bolted together easily and was setup in around 20 minutes – the only thing I didn’t like was the lack of proper cable management and the excess of cable if you install how they recommend.  Cable ties are your friends!

The base unit is pretty easy to setup and pair (took a few seconds to pair to the  external sensor) but the included manual isn’t overly helpful on the finer settings, yes it tells you how to set them but doesn’t explain what they do or what they mean (example is absolute pressure vs relative pressure and its locality offset).  The Ambient manual is much better for this.

Oddly the base unit has a back light, I say oddly because its only on when you press a button and then only briefly – to be honest its a bit pointless because if you can’t see the screen you won’t see what button you are pressing!  It would however be a nice feature if the base station could be mains powered.

So now I can see both internal and external temp, internal and external humidity, date/time, current weather and predicted weather (based on pressure changes and temp changes), pressure, pressure history, rain history (last X hours) and either average wind speed or max gust speed.  There is also a history option to show minimum/maximum recorded values and, alarm storm warning and a normal alarm.

After lots of rain, frost, wind and sometimes some sun this unit is still going strong, the plastic is still plastic but hasn’t broken or fallen apart – lets see if we have another 8 months of life!


As above yes, this is my 3rd unit – the other 2 (and this one) suffer from the same major fault, the unit spec shows it will handle external temps of -40C to +65C and that the outdoor sensor has a battery life of upto 24 months.  Once the external temp drops below 2C the battery life drops, so much so that a fresh set of batteries will last less than 2 weeks in the external sensor if you have a few cold nights (when I say cold I’m talking around -4C as the lowest temp).  Maplin recommend alkaline batteries for use in the sensor, Ambient recommend lithium batteries when in cold climates, guess which ones work best!


For someone like me who is more curious about the weather than just looking outside but doesn’t want to spend a fortune then this unit when on offer does the job that I need, yes it would be nice for a little more info (such as wind direction and better prediction/longer range) but then you are talking quite a jump in cost.

Just remember, lithium batteries will work in the winter better than alkaline but there is a cost difference when buying them, or buy alakaline but be prepared to change them often if its cold.

Interestingly, Ambient discontinued this unit because of a few issues but Maplin still sell it as the current unit.  The current Ambient version is WS-1075 which looks almost identical except the base unit is a different colour and they condensed the external sensors into a smaller footprint.

Update – 01/11/2015

The outside sensor needed new batteries so I followed the instructions and replaced said batteries……..and it went all wrong!  The actual replacement was easy, but it lost connection with the base unit and the only way to resolve this was a full reset of the base unit.

Update – 15/02/2016

Well it had to happen, we have a dead sensor – apparently it’s not rained for the last 2 weeks, this is Wales, this is a lie!  It looks fine and the principal of the operation is fine but its dead.  Oh well!

Update – 03/08/2016

2 months ago I decided to see why the sensor wasn’t working – it appears that rain water had caused a build up of sludge which covered both the switch and the collection well hole, cleaned both of these and poured about 2 litres of water through it and its working like a treat.  On the other side, I have had to change the batteries in the base unit and the sensor again 😦

Update – May 2017

Well the cheap plastic has come to the end of its life span, the weather guage has crumbled into many parts, the rain gauge is held on by luck and cable ties and the main housing is falling apart – so its just less than 3 years old and its at the end of its life, now considering the claimed battery life is meant to be 2 years, the 3 year life span is poor.  On the positive side it was only £25 so thats about £8 per year plus a few sets of batteries.

    I’ve had one of these units going for 6 years with no problems. Tip : don’t believe the ext. Sensor low bat warning. I used Duracell, ignored the batt warning and got a further year out of it!

      My battery warning was normally followed within a few days by no readings from the external sensors – this unit has out lasted my previous ones though so its doing well so far, I’m wondering what this winter will bring as I’ve moved somewhere that does have colder temps in the winter months.

    I have a weather station N25FR which is consuming batteries in the outside sensor. They last on average 2-3 weeks. I live on the South Coast, so excessively cold temperatures are not an issue. I have been using Duracell batteries, but the bunny seems to have gone on strike! Any suggestions?

      I tried all sorts of batteries and found most of them were poor, I ended up buying GP Ultra batteries from Amazon with the plan to change them more often as they are cheap – oddly they seemed to last longer! I was going to try lithium rechargeable batteries but as the unit has fallen to bits the only surviving part is the temperature sensor which is now mounted on the side of the house in a less exposed position.

        Thanks for your comments. I think I might try lithium batteries next. The batteries that came with the weather station originally lasted about two years, which leads me to believe that maybe there is some sort of short circuit outside in the station, which is causing the batteries to fail.

          Disconnect the other 2 sensors (wind and rain) and see if that makes any difference.
