Well, yesterday I managed to find a way to modify the door opening sensor. Instead of a magnetic sensor, I soldered a physical switch. I will place the switch inside the door frame.

Each time the door is locked with keys, the sensor will send a status update confirming the door is closed.

The most interesting part is that a lot can fit inside the door frame: 2 WiFi sensors, 4 AAA batteries, and 2 physical switches.

I’m waiting for the delivery of several cables. After that, the issue of whether the door is locked will be permanently solved. The status will always be available on the phone and can be shared with family members.

It’s strange that no ready-made solutions could be found on the market.
