I’m just going crazy to configure static IP
I used to do that to because I had no better option but you can do better.
However, if you can, you should not use static IPs.
They results in many problems and extra work. That being said, I am NOT saying you should not have a fixed IP for your OpenHAB server, read on…
My recommandation is:
- leave your RPi in DHCP
- tell your router about the Mac Address of your RPi and either let your router’s DHCP provide a random address from its pool, OR setup a static IP in your router so that your RPi always gets the SAME IP, when its DHCP requires a “new” address. This way, you control everything in your router.
- finally, make sure your router does handle the
hostnameof your RPi (it will be openhabian by default but you can rename easily usingopenhabian-config).
So in the end, you can reach your OH via its hostname, ie openhabian, or openhabian.yourdomain.com or whatever hostname you set set and whether the IP of the server changes or now is up to your router/DHCP server.
It is also better this way if you ever decide to setup Firewall rules.
There are many benefits:
- your RPi remains in DHCP, it does not need to know about an address that may also potentially conflicts with otehr devices
- if you need to clone your RPi, your router will provide ANOTHER IP since your Mac Address changed … so you can have both systems running in parallel during the migration
- you can still decide and change your mind, from your router about the fact that your OH has a fixed IP or not (I would recommend a fixed IP…)
