Lock Manager DOW and Time-of-Day access

You’re on the right track here.

If you have access to RBoy Apps you can try this app and use the modes to control access.
The changes will happen within a few minutes depending on how many users you have. You can configure it but the default is 15 seconds per user. With 8 locks I’m assuming you have lots of repeaters installed and if you have a strong Z-Wave/ZigBee mesh you can speed up programming users to every 5 second. So for a single lock to program 30 users should take about 2-3 minutes (if you have a strong mesh).
