In case anyone else has a European-style door installed, I wanted to share a fun project I did with a ZEN17 Universal Relay that may help you out too!
We live in the Chicagoland area, and we recently had Erkado doors custom-designed, built in Poland, and then shipped over to the US to be installed on 4 exterior door locations on our house with push-bars instead of door levers on the exterior (see below photo of our new front door as an example). We loved the modern look and increased security of the Erkado doors, and the pricing wasn't terrible for steel doors.
As such, instead of the (optionally lockable) door handle and a deadbolt that's common in the US, these have a more secure multi-point lock (think a deadbolt) on them, which we have controlled by the Tedee Lock Pro (+keypad and bridge). However, if the "deadbolt" isn't engaged, the strike (think door lever, only openable from the inside where there's still a door lever) is still in a locked/secure state, meaning you'd need to use a code every single time to "unlock" the door from the outside, unless you remember to flip a small switch on the strike, which then allows you to just push on the push bar to open the door (similar to just opening the lever of an unlocked door). However, if this is left on all the time, if there's any negative pressure and the "deadbolt" isn't engaged, the door can be opened unintentionally (obviously not desired).
I found out that the strike is actually an electric strike (Roto 891785) when the doors were installed, and that we could "upgrade" our doors with a push-bar with a button on the back, which would be powered by a 9V replaceable battery in the bottom of the push-bar that sends a signal to a relay to unlock the electric strike. As we live where temperatures can get cold during the winter (and it was like $800/door to upgrade the push-bars), I decided to come up with my own solution. I had some photos provided to me with what the controller/power supply that's officially used looks like/power requirements, so I was able to deduce some information based off of that, and then recreate a solution that works even better (at a fraction of the cost)!
See below for a wiring diagram that I put together of my solution:
Within HE, I have a Zooz ZEN17 paired with Relay 1 Input Type set as a "motion sensor", so I can detect when someone uses the wave-to-open sensor, if I'd also like to add automations later (e.g., send a notification that someone tried to use the wave-to-open sensor, but couldn't open the door - detected by contact sensor - indicating someone can't get in OR is trying to break in). I also have the Input Trigger for Relay 1 enabled. Then, by adjusting the trigger duration on the SecoLarm SD-9163-KSQ, I'm able to have the electric strike unlatch for 5 seconds, allowing the person to push the door open before the latch engages again (provided the Tedee "deadbolt" is unlocked). This solution has permanent power, so I won't have to replace batteries (which wouldn't last long in the winter temperatures), and with it being a wave-to-open sensor, as long as we put our hands on the push bar where that sensor is, it automatically unlocks the electric strike without needing to push a button!
