The Pixel TW-282 listed will do intervalometer. The Yongnuo model looks like it has identical functionality.
Just noticed Pixel list a TW-283 looks like the Yongnuo. FWIW the 282 uses a CR-2 lithium battery in the receiver, the TW-283 and I assume the Yongnuo use AAA's so may be cheaper to maintain.
