I can recommend ecowitt ( I have
this one expanded with a few additional sensors )
Apart from ws90 you have different option to choose from ( see this post for the complete list:
https://www.wxforum.net/index.php?topic=40730.0 ):
- ws65 external sensor all in one ( 7in1 )
- ws68 external sensor ( cup wind sensor, light )
- ws80 external sensor ( ultrasonic wind sensor, light, T/H )
- wh40 rain sensor
- several T/H sensor
- soil moisture
- air particulate
...
- gateways ( gw1000/gw1100/gw2000/wn1900/wn1910 )
- consoles ...
Available in europe ( with different brands ) or directly from china.
Final note, great customer support directly from ecowitt
