OPTIONAL ACCESSORIES
2 Wire Magnetic Reed Switch
Reed switches are used to monitor the opening and closing of windows or doors (or essentially anything that opens or closes). There are two parts to a reed switch... one has a magnet inside, the other a reed switch (which is triggered when the magnet comes close and deactivates when the magnet is pulled away). When wired (DIY with 2 low voltage wires) to a smart home binary sensor input device, you can easily monitor and create automations for doors and windows. Can be mounted with double-sided tape or screws.

Product Questions & Answers

Has this model been assessed for Australian Electrical safety requirements? I want this version with the 3 isolated contacts, but I also want to be sure that I'm above board on the electrical safety front. A quick search of the EESS only brings up Shelly 1L, Shelly 2.5, Shelly1 and Shelly1 PM. I don't see the Pro 3 listed.

Very easy for the electrician to install.
When setting up schedules through the app, they’re out by 1 hour, so a heads up for anyone there.
Had the first trip off due to over temperature today, checked the front of the device soon after as I was home and didn’t feel too warm to me, but being an electrical engineer my idea of too hot is vastly different to others. Was able to turn one of the loads back on stright away so no big concern there. I did have 2x 16A loads running for over 2 hours consecutively to get to this point.
