RFXcom on HASSIO problem

I’m running Hass.io on Rpi4B; i’m using Rfxcom to control 7 SOMFY covers, and receive data from one Oregon THGR-221 Sensor and one Owl Electricity Monitor.

The 7 covers are working very well, even though two of them are at 20 meters from my Rfxcom.

But i have an issue with the Oregon and Owl sensor. Most of the time, when i restart Hass, my Rfxcom receive no signal from them, cards stayed with the message “Entity is non-numeric”

Owl and Oregon are at 5 meters from my Rfxcom.

Sometimes trigger the sensors help, sometimes no; do i have to trigger every time i restart Haas?

Appreciate your insights and help, thank you!
