Hello dear specialists,
after the Pimatic updates on my test-PI, I was also able to update the node version (8.16.0) on it.
So there pimatic 0.9.48 is running on node 8.16.0. (One problem I recognized currently is, that the Homeduino Shutter3 devices seems not to work)
After that I thought, OK, lets update also the node version on the prod-PI, … I shouldn’t have done that … 
Great mess, absolutly nothing worked - I have no clue why.
After hours of testing, I thought to make some copies of the config.json and the -database, delete
the complete pimatic-app directory and also the the other node and node_module directories in /usr/local/…, and install node and pimatic completely new, according to the installation guidelines.
I first took the guideline from the Wiki: https://pimatic.teamemo.com/Guide/Getting-Started which I saw is already working with node 10.x. But that doesn’t work.
Using: 'npm install pimatic --prefix pimatic-app --production’
Results in:
/usr/local/lib/node_modules/npm/node_modules/npmlog/log.js:57
log.progressEnabled = log.gauge.isEnabled()
^
TypeError: log.gauge.isEnabled is not a function

… and the pimatic-app directory stays empty.
I then took the old guideline: https://pimatic.org/guide/getting-started/installation/
which results after 'npm install pimatic --prefix pimatic-app --production’
in:

However, having now a full pimatic-app directory, I copied back my config.json and the -database and also the fromerly saved plugin directories and started pimatic.

… but I’m not able to reach the front via browser, nether via PC, nor via iPhone.
Has someone an idea on that?
Many thanks in advance.
Maybe I have to learn them again to pimatic - we will see.
