Super gluing it... not a very good idea.
I've had similar fuckups like this. what I did was I used a bit of cloning gel to smear between the surface and used twisted ties to tie the broken branch to the opposite branch, it worked. But my plant was way younger than yours so I don't know if this...
IOT is great for growing though...I've seen people diy their own hydroponics temperature sensor based on IOT so they can check their solution temperature at work and log the hourly change of solution temperature throughout the day via their phone...pretty neat.
