I just connected the H2C to my network and started my very first print. Slicing and sending data to the printer appears to work.
However when I go to the Multi-device tab in Bambu Studio, I am only seeing my older printers (A1 and X1C). I do not see an option to add the new H2C to the list of devices.
Just noticed the same thing after enabling. I hope this is fixed soon.
Nothing new, still not showing H2D either:
I am having the same problem.
Same issue here, H2C and X1 show up, H2C does not, eve though its showing up just fine on the “Device“ tab
I sent a bug report ticket to Bambu support. They replied stating the H series is not supported on the Multi-Device. They didn’t say if it would be in the future or not.
no luck with my H2D or H2DPro, but my P2S shows up!
Just had an update to Studio and crossed my fingers!
Alas, no joy 
I opened a support ticket about the H2D.
I have a 2 H2C and 2 P2S. It is nice being able tin see the status in one place. The H2D should be there also!
D.
Mine shows H2D but no H2C
Same here. Only PS1, No H2D
