Weathersensor app

I’m trying to connect two La Cross TX… sensors with the weather-sensor app. No succes.
A Cresta 433 MHz is not stable.
What is the best, cheap, weather sensor (outdoor with humidity) for Homey? I need 3-5 sensors to monitor the temperature outside and in different rooms.

I gave up on using wheatersensors with homey. It always worked for a while and then suddenly stopped. Then after resetting I had to include the devices again. I am now using rfxtrxE. No problems encountered after that. I send the data to homey using a webhook. Alternative would be zwave or Zigbee sensors.

Indoor i use heiman temp and humidity sensor. (Ali expres about 25 euro)
Outdoor i use Philips Hue outdoor sensor for movement, temperature and brightness.
