In this case the Linked Trigger would be an InIg effect with 2x/day, D: Sun, and Environmental Trigger that "Activates" when it senses light (hopefully of more than minimal brightness so it won't fire off everything when you open the door).
Limiting the "Activator" for Linked Triggers to some form of Intelligo effect, while it does not stop all of the madness from pom-pom-wands, maxim wands, and other such crazies, does increase their difficulty and reduce/remove some of the most abusive ones. Groups I play with have normally limited the "Activator" effect to trigger varies Linked Triggers based on differences in its sensory effect.
For example InMe of sufficient level can understand speech (rather than just listening for a command word). Combine this with a Mu and varies Form requisites to "Awaken" the effect so it has a "memory", allows you do do things like tell it "Trigger Effect A if this happens". Along with a magnitude or two of Complex (on it or triggered effects) lets it follow extremely complex commands.
One I have used is In(Mu)Me(Te) as the "Activator" effect for my Enchanted Lab. It is primarily an InMe to understand my speech, the Mu and Te is an "Awaken" enhancement allowing it to remember commands and sense things. This was needed to cover lab activities, air quality/temp, room light/temp, position of lab equipment, and things like spills. It triggers things like an enchantment giving a breeze with temp ranging from cool to warm, room light from no magic light to cloudy day, ReTe that controls/moves the varies lab equipment and tools around, and a PeIg effect that extinguish all fires in the room. All of them except the fire extinguisher are D: Concentration/Item Maintains effects to allow them to be tweaked while active. Hey, I like my voice controlled AC and lights.
