I’m trying to use Simpex triggers with a Yongnuo flash. Will they work together, and are there any limitations for basic firing versus features like TTL or remote power control?

This question is entirely dependant on what Yongnuo flashes you intend to use. And what Simpex flashes you intend to use.
In a basic sense both the Yongnuo and Simtex triggers should would perfectly fine together providing that the Simpex triggers have either a standard Female Hotshoe.

Or a PC sync socket. (This is the plug on the right of the image).
If you are looking for more advance functions such as wireless TTL or Flash Power Adjustment then the answer becomes more complicated.
You will firstly need a TTL enabled Yongnuo flash and then have TTL compatible Simpex triggers. Please note the triggers and flashes will have to be for the same system. E.g. if you have Canon fit Yongnuo than you need Canon compatible Simpex triggers.
In terms of more advanced functions you may be better off using Yongnuo own proprietary trigger system such as the: Yongnuo YN-560-Tx trigger which will work in conjunction with the built in radios transmitters that Yongnuo is now including with there newer flashes.

For things like HSS you will need to make sure your triggers are compatible of transmitting within 1/8000s of a second.

Usually yes for basic flash firing, but it depends on the exact trigger and flash models.
For simple manual triggering, a Simpex trigger should work with a Yongnuo flash if the trigger/receiver provides a standard hot shoe connection or a PC sync connection that matches the flash.
For advanced features such as TTL, wireless TTL, or remote flash power adjustment, compatibility is much more specific. You would need:
- a Yongnuo flash that supports those features, and
- Simpex triggers that also support the same feature set.
They also need to match the same camera system. For example, a Canon-dedicated Yongnuo flash would need Canon-compatible triggers for TTL-type functions.
So: basic manual firing is often possible across brands, but advanced automation depends on exact model support and system matching.
