Hi,
Has anyone been able to get the rtl\_433 node (which needs rtl-sdr and rtl-433 Installed locally in the environment).
The issue seems to be that node-red docker is using node 10 or 12 with Alpine v3.11.
Trying to extend the node red docker image and build both rtl-sdr and rtl-433 results in errors with the udev rules and gives USB error 3 (access denied) - running the docker container with either USB devices mapped or in privileged mode doesn’t change this. The rlt rules are there.
I see rtl-sdr does have a package which can be installed with apk in alpine v3.12...
Any thoughts? Has anyone got rtl\_433 and more red working in docker?
