I’m using HA for almost more then a year and I love it.
At this point I have HA running on my Synology NAS at my home, a great extension on my Beckhoff PLC.
For some other projects I’m facing some problems.
The use case is to implement HA on a RBPI 4, in combination with a Beckhoff PLC (trough the ADS component), in a situation where there is no router and/or internet connection availble.
Because there is no router availble, all devices in the network have a static IP adress.
To do this on the rasberry PI, I use this guide: https://pastebin.com/rrg6ujBX
So I enter the static IP, subnet, also with a default gateway “xxx.xxx.x .1” which is actually not present. Also the DNS is entered, but this is also not present.
Home assisant will not come availble at :8123. Ping is possible.
When I change the network configuration file back to “auto”, and connect it to a network with internet connection the HA instance becomes availble.
So can anybody help me with the settings to use the HA instance on a RBPI with a static IP with no internet connection?
Note: before going into a network without internet connection, the initial HA configuration was done in a network envirement with internet connection.
