i need to automate a wine cellar using AC.
the cellar is at my friends nanny home, and thus not connected to the internet.
in order to not make him to pay an internet connection i thougth to implement a home assistant automation through a lan in in which a bunch of nodemcu and broadlink RM mini do the heavy job.
mu current problem is that if the raspberry which mounts the hassio is not connect to the internet then it will not sincronize its own time and date resulting that the recorder doesn’t work. (i end up with an empty database)
i thought that a possible solution could be to connect the raspberry to the modem via ethernet and connect it trough wifi to an hotspot i make with my smartphon ( just to make the time sincronization).
in order to set all the connections i tried to set up che add-on alles SSH Web Terminal but it gives me an error if i run it when the hassio is connected just to the lan (and so not to the internet)
Yes, but the problem is that actually the cellar is made out of three rooms and so three AC… I’m kind of forced to use three different nodemcu… Also I will have the same problem, since it is related to the fact that the place doesn’t have an internet connection
I have the raspberry pi in a LAN which is not connected to the internet… To make the time sinc, I have to connect it to the internet…
I thought, I can use the WiFi to connect it to an hotspot created by my smartphone and the work is done!..
Well it’s two days that I’m trying…
I found out that by using the SSH web terminal i can modify both ethernet and WiFi connection… But it seems that this add-on needs the internet connection itself… So… I’m stucked anyway…
I wonder if there is a way… Like the one I use to set the WiFi connection settings ( saving the my-network file in the SD card under CONFIG/network)… To set both ethernet and WiFi connection … In order to have both available for the raspberry pi…
I did some research…
Apparently one option could be to install hassio from docker… But with the new debian-buster it seems that docker is not working… Have you got any experience?
And still I’m not sure yet if the hassio will sinc the date with the raspberry (so RTC) or with the NTP…
My problem seems to be not possible to solve easily.
I’m starting to think that i should connect the cellar to the internet
Does Hassbian this too?
Then might be a good chance.
Anyway it might be possible to install your preferred distro and use python virtual environment or to install docker and activate the homehassistant container.
I’d rectify that with docker might be a little problem to pass the time information to the container. Perhaps the host should do as NTP server, with its RTC.
