I did it. After a backup i removed ‘node_modules’ and installed pimatic new as @elektronaut in the other thread (see posting above by @mwittig) suggested. ‘config.json’ and the database stayed untouched. Compilation after pimatic start took a long time but now web frontend is working.
One issue remained (possibly came new). Alle my ESP8266 device use the api to read and write pimatic variables.
All these calls end in an error .

Same problem also for other plugins (one error above comes from pimatic-dwd plugin).
New starting of pimatic does not help. The user is declared in ‘config.json’. Is it a problem between new installed pimatic and old database?
