Hi,
update: The “Local Networks (no username/password)” suggestion for Domoticz users works: also the HTTP JSON API works without password if this option is used. It is possible to add specifically only the OS IP address as “Local Network” instead of a range. Only disadvantage: This setting is not per-user, but global; anybody with the specified IP (range) will have full *Admin* rights in Domoticz (but then again… if an attacker is already in the position to spoof IPs in your local network, you have major issues anyway…)
Will report again in a few days if this also solves my stability issues that came up after firmware update + using long URLs for switching.
Thanks again Pete!
All the best,
Till
