What word should I use?

I'm writing something about smart devices. The thing is, there are sensor-based automatic devices which follow predefined rules and react to inputs, and there are also machine-learning–based devices that can adapt and improve over time.

I wish to refer specifically to the lower level (the rule-based, sensor-controlled type). I've considered terms like "light smart device" or "simple smart device," but I'm not sure those sound natural or are commonly used. Or is there a better or more standard term for this category?
