Photocell connection

How many lights can I connect to a single photocell sensor? If you’re able to provide wiring diagram, it would be perfect.
Thanks in advance for any input

Not sure I understand what you mean?

What smart device is a “photocell sensor”?

As for how many lights you can trigger with Smart Lighting rule or CoRE or other software link from a Motion Sensor or Contact Sensor … It is pretty much “unlimited” (but there might be a practical limitation and/or perhaps a hardcoded limit in the platform).
