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.

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.
