Great for koi pond

Received this a few days ago, I'm using it to track the temperature in my koi pond so I can feed the correct food throughout the year. Very quick delivery and a much better price buying direct from the manufacturer.
Very happy with my purchase and will definitely be buying from here again.

Steve Thompson

Very easy to connect. Added a battery and it immediately connected to my existing network.

Perfect sensor for my spa!

My spa temp sensor is in the pump so I wanted a more accurate reading of the water temp when I wasn’t using the pump. Since I had an ecowitt weather station I figured I would try this. I was amazed that as soon as I put in the battery it was communicating with gw1100 and I was immediately seeing the temperature read outs. Really happy with this product and thinking of getting more accessories.
