I have a problem with i2c ADC in the subflow.
If I add a subflow with i2c device in flow, the first time it works fine, but after I remove the subflow and deploy, i2c still works.
Further - worse. If I add and remove subflow second time, I see have 2 subflows works simultaneously without any subflows in flow.
I made a small video with timeline comments to show the problem:
Raspberry Pi zero W.
Node-RED version: v0.20.6
Node.js version: v10.16.0
Linux 4.19.42+ arm LE
Does anybody know how to solve this problem?
