I connected sense hat to my pi when it was turned on. I know, A big mistake. I would like to know how to know if my sense hat shield is "caput". I am traying to connect it with Node-red. But show all the time as "disconnected" and not leds are shinning after running a *.py basic for leds.. Any idea how to test if it is working and if not there is any possibility to take it back to alive.
Thanks for any help-
