Hi!

I used My home monitoring before with raspberry PI and some term sensors and used MySQL node on my solution. Now I want export some configuration from my old to emonpi node-red, but when I try install node-red-node-mysql - over “Manage palette” or directly from ssh terminal then I get some errors,
sudo npm install node-red-node-mysql

How I can install some nodes to node-red in emonpi ?

Thanks I find the answer :wink: must read when I logged to ssh terminal — there is written :wink:
“The file system is in Read Only (RO) mode. If you need to make changes,
use the command ‘rpi-rw’ to put the file system in Read Write (RW) mode.
Use ‘rpi-ro’ to return to RO mode. The /home/pi/data directory is always in RW mode.”

thank’s now all works :wink:
