Hi peoples!
First time posting for me on this beautiful forum.
Just got TT, Ansible and Grid.
Everything is super confusing, but I love the outlook of one day understanding a bit of what‘s possible with this powerhouse combo. 
First question:
I hooked up TT, Ansible and ER-301 with the I2C multi cable. Not because I know how to use that functionality, yet, but just because I could.
When I plugged Grid into Ansible, some buttons in the upper left corner shortly blinked and then… nothing.
I re-plugged Grid a couple of times. Same scenario.
After I pulled the I2C cable from Ansible everything worked fine.
Is this normal?
Cheers for all the great and friendly minds lurking on lines!!
