I did do it a while ago with my system when I managed the remote access myself and remember it to be a bit of a faff.
I moved Internet providers and the new one didn’t have inbound traffic enabled so it stopped working. Rather than go through the hassle of contacting support to allow incoming traffic I signed up for Nabu Casa. It was a lot easier than setting up the security myself and it made Alexa integration trivial.
So if an annual or monthly fee is an option then it’s worth considering.
It looks good.
I want to do something similar with an Android tablet so that I can replace the Amazon ad delivery system in my kitchen. All I use it for now is timers and a shopping list.
I never get the time to do it though.
