Telldus 433Mhz SEnsor

Hello! Search the forum but cat find an answer. I have a lot of 433Mhz Telldus sensors that I want to use in Homey. But how?
Fisrt I imported them with the Telldus App, they appear, but never updates
Then I added the “Wireless Waether Sensors” - 3 of my 10+ sensors show up, why not the rest? 2 of them are 2 dm apart (refrigerator and frezeer)

Any help appreciated!
