There is a bit of information is this topic [APP][Pro] Misol and Ecowitt (version 0.1.10 and test 0.1.14 )
The main thing to check is the gateway and device are using the same frequency as they have 3 variations for different parts of the world.
If you want to provide links to any devices I can check the spec to see if they are supported.
The weather station I have is this one Misol / Outdoor Sensor (spare Part) For Weather Station (ws2320) Wireless 433mhz - Thermometer Hygrometer - AliExpress
and I have this gateway Misol Smarthub Wifi Gateway With Temperature, Humidity & Pressure Gw1000 - Thermometer Hygrometer - AliExpress
(edit, sorry voor het Engels, ik was vergeten in welke sectie dit stond)
