 Product Description

A professional grade weather station coupled with a 7-inch/17cm colour LCD that will measure almost anything planet earth can throw at it. It's capable of displaying temperature, wind speed, wind direction, wind chill, barometric pressure, and dew point.

These readings are sent from the outdoor solar transmitting sensor and indoor sensor built into the display. You can see how much rain has fallen in 1 hour, a day, a week, or a month, see the current UV index reading, and even see the current lux measurement outdoors which is great for those who have rooftop solar arrays. Install the sensors outside and the readings will be transmitted wirelessly to the base unit up to 100m away.

TESA newest professional WiFi weather station allows you to monitor your home and backyard weather conditions with the brilliant, easy-to-read LCD color display. The enhanced Wi-Fi connectable option that enables your station to transmit its data wirelessly to the world's largest personal weather station network, Weather Underground and view data on your mobile device.

  1. Great product and exceptional service.

    Posted by Craig, Nelson on 12th Aug 2021

    I ordered this online and it arrived the following day. I am in the South Island and was thinking at least a couple of days - so thanks to your team for getting it shipped so quickly.

    Loving the product itself, easy to install and the Wi-Fi process really easy to set up. Data is well displayed, easy to read and I now read the data and graphs on my phone and/or via websites and and have even taken to looking at other data sets from weather stations around my area.

    Thanks Heaps

  2. Great piece of Kit

    Posted by BB on 22nd Feb 2021

    This arrived really quickly and was easy to set up. Connecting it to the Wunderground network was a little challenging but it is now on. The PWS Monitor app from apple is really good and allows you to see your PWS data directly. Very happy with the gear.

  3. WS2900C=Pro weather station

    Posted by Roger Beckett on 27th Jun 2020

    My wife and I purchased this weather station to replace the damaged console of the equivalent product that was no longer stocked by Jaycar. The new console picked up signals from the former sensors.

    We're very pleased with this 'toy'. It displays weather data clearly. Yet to connect to wi-fi but intend to download the app and upload data to the Ecowitt service.
