Good day,

I need some help with my PiJuice zero.  
From the CLI command line interface I changed the i2c address to 15.  
How ever, the command line interface it self does not change to 15 so it says comm failure from the moment I changed the address.

I've installed the node-red-contrib-i2c as I thought I must be able to change the address back to 15 with it.  
However, I searched and searched the interweb, but I cant find anything that tells me what I need to write to address 15, inorder for it to change back to 14.

Anybody got some ideas on this?
