Home assistant callback IP addresses


I configured my Home Assistant with my SmartThings account (I have a washing machine now).
My home assistant has public IP address, and also a valid let’s encrypt certificate (which renewed on port 80) My https (443) to the HASS is by default: disabled, since I don’t want anyone trying it from outside. My problem is, that the smart thing want’s to call an endpoint on my HASS (push notifications AFAIK) but it can’t since the firewall blocking the outsite.

I would like to have a list of IP addresses, which is used to do the push notifications from the SmartThings side (an xml/json/any parseable) updated online list would be the best :slight_smile:

Is there any list, or possibility to do this?
