- Platform information:
- Hardware: Raspberry Pi 4, 4 GB
- OS: openhabian
- Java Runtime Environment: which java platform is used and what version
- openHAB version: 3.1
we bought a raspberry Pi4 and installed openhabian via the SD Image.
We had installed openHAB on an Synology NAS earlier and found the same problem:
Light Switches in openHAB don´t work. They worked if we connected via HTTPS.
If we try to connect via HTTPS we get the message, that the certificate is not valid.
Is there a way to correct the default certificate?
Or is there an easy to understand documentation about how to install a Let´s Encrypt certificate on openhabian?
We are very beginners with raspberry and openhabian and we searched the documentation, the forum and the web for hours.
