There are LOTS of digital photo frames that use SD card or micro SD card storage to hold photos.

The first ten frames that came up when I searched Amazon all support a memory card, ranging from 32GB - 128GB, depending on the device.

If you don’t want to bother with a smart solution, I use one of these Inkbird Heat Controllers:

You can set two different temperatures - one for day and night. It can handle heaters rated up to 13.5A or 1500W.
