Session 2 - Dry Contact Relays

Thanks to a quirk in Meetup's notifications, nobody was notified about last month's "Wired for Shelly" events, so I'm giving it another go!

This session will cover dry contact relays - how they're different, when to select them, and how to wire them. These are truly useful - and when you need one, there's no substitute.

If you can't join the evening meetup on Friday, March 27th, we have a morning session at 11am!
