Does anyone know if the HomeAssistant 0.55 release now incorporating DuckDNS includes automatic encryption like, I believe, the HASS.io add-on does? It doesn’t look like it but I’m pretty new to this. Thx.
It does not. The language in the .55 release is horrible and makes believe that it includes renewal of SSL certificates which is not true. The DuckDNS component does however renew your DNS namespace for you though. Currently you either renew it on your own manually OR you have installed the DuckDNS script on your installation and have a crontab (scheduled job) renewing it for you. The DuckDNS component removes the needs to install DuckDNS and create the crontab job.
Thanks… that’s too bad. I’ve thought of switching to Hass.io which, I believe, has the DNS and encryption implemented in a more user friendly way… but I almost have everything running on Hassbian …so I’d hate to throw that all away.
Unless you’re running a strange set up is unlikely you’d be throwing anything away. You just copy your old config into the hass.io install and make a few simple tweaks. If you’re using anything manually installed just check to be sure there’s an add-on to cover it, the most frequently used ones all exist, and away you go.
The only somewhat odd thing I’m doing is using 2 python programs that implement pyserial to turn my projector on and off via rs232 connection. A script calls these via a command line. Anyone know if command line calls from within a HA script are supported by hass.io. Thanks!
Well, the answer is no… can’t run python scripts. Documentation appears to say that I can write a local “add-on” but looks complicated. Not sure which direction I’ll go. Thanks everyone.
I’m sure there any many other ways you could turn your projector on and off that are currently available if hass.io but if the hassle of doing that outweighs any advantages you think changing will give you I’d stick with what you’ve got for now 
I did take a stab at writing an add-on but the more I learn the less it looks applicable to code that will only be run once in a while. I do like hass.io so I’ll continue to look around a bit. So far, however, I haven’t seen anything that will allow me to interface to a projector that only has a serial port. I’ll keep looking and update if I find anything that works. Thanks!
how to use this component with multiple domain?
