✅ Future-proofBuilt to keep working — even if the maker walks away.
It works locally over Z-Wave, so it keeps running even if Siterwell Technology shuts down the app or the servers. Nothing here ties you to a single company's survival.
Works locally over Z-Wave — keeps running without the maker's cloud
Still in production
Based on how this device connects (local vs. cloud), whether it’s still sold and supported, and its app / subscription. A guide, not a guarantee.

Door sensor is an intelligent security equipment that can transmit the Z-Wave network which has particular frequency. In the Z-Wave network communications, door sensor can be connected to any Z-Wave main controller (ex, SiterOne tablet). The door sensor can send messages to the Z-Wave main controller, and realize association with other devices through the Z-Wave main controller. Different countries or areas, the radio frequency is different. In the communication with the Z-Wave main controller, the door sensor can send messages to the Z-Wave main controller, but it cannot receive messages from the Z-Wave main controller. When alarm is triggered, the door sensor sends messages to the Z-Wave main controller, the Z-Wave main controller will displays the current status of door sensor, so the door sensor can associate with other devices. Door sensor is battery powered, is small and can be installed on the window or door easily. When the door or window is open, the door sensor is triggered and linkage alarm realized.
Want to buy adds it to your wish list and follows Siterwell Technology for updates. I own it adds it to your collection.
