Just got a dendrobium division

[Onomaya]

So, I just got this one from my grandma, who got it from someone else. All my grandma learned about it is, that the previous owner called it "cinnamon orchid".

I haven't been able to detect a cinnamon fragrance yet, but it does have a slight perfumy smell.

The flowers are rather small compared to my other dendrobium phalaenopsis at about 3 cm/<1 inch.

I also attached a photo of the way it's potted, cause I'm strongly suspecting that I need to repot asap.

I hope someone has a clue what this is.
