I, too, think it's a Dendrobium kingianum, or possibly a hybrid (x delactum, or another - or possibly a different, but similar species)
Den. kingianum is also known as the pink rock orchid, native to Australia

They can take a wide variation in temps, tho it seems they like to get cool in fall to initiate blooms, tho there is a good deal of conflicting info on blooming this plant ...
But they can take short periods of slightly below freezing, and I know mine at least takes short periods of near to just over 100 F.
It's quite dry in summer where I am, and so long as I don't allow the potting media to dry out, this plant does fine. Reduced water in winter (I still don't allow mine to dry completely in winter, but don't water as copiously as I do in summer).
Moderate to bright light - tho direct midday sun in summer can burn it.
Because this is lithophytic - I have mine now potted in a mix of perlite and pumice, tho I know others grow successfully in bark mix ...
