WN30 temp sensor ( 3 pieces) with sensor cable + gateway GW1100 (1piece)

This package was delivered yesterday, December 14th 2023.
Tried to install the gateway GW1100, but without succes. I followed the instructions very carefully. Although I have experience with Ecowitt devices and the gateway GW1100. Could it be that installing a second Gateway GW1100 is not working when working together with a previous one ?

Exactly the right device for my project

I needed a wireless 433 MHz temperature sensor for my ice bath setup and this device meets all the requirements. Works great with my SDR for temperature logging so I can see how cold my ice bath is at all times

WN30 review

Great product, use it for temp check in fridge and freezers.

Great Customer Support

I bought WN30 to measure my pool temperature. Easy set up (paired with HP2550), everything worked fine. After 10 days suddenly temperature showed 60 degree Celsius (max. temp.) and stayed that way.
After asking customer service, they quickly responded with probably root cause, added pictures and described how to solve it.
Now it works fine again.
Of course, it would be better if no error occurs, but if customer service supports in this way it definitely is ok.
I am satisfied with ecowitt.
