Add off_delay to an automatically create rfxcom sensor

I’ve use the automatic add option on RTXcom integration to automatically add a binary_sensor for a rf button ( PT-2262).
This work fine, but I need if to have the off_delay: 0.5 sec option added to this entity for it to work correctly.

How/where do I do this?
Or do I need to delete it, and add it manually.

Thanks…

You have to manually configure it in RFXTRX integration as described in this article (RFXCOM RFXtrx - Home Assistant).
