✅ Future-proofBuilt to keep working — even if the maker walks away.
It works locally over Z-Wave, so it keeps running even if Everspring 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.

The EH403 is an outdoor security floodlight equipped with Z-Wave wireless communication capability. It features a PIR detector to detect motion through movement of heat sources and a lux sensor for determining brightness of its surroundings. When not connected to a Z-Wave network, EH403 is fully operational as a standalone security floodlight. During hours of darkness its PIR detector turns on the 20W floodlight when it detects movement in the protected area. Its built-in timer will then turn off the floodlight after a preset time has elapsed. During daylight hours, its lux sensor saves energy by deactivating the motion sensor and the floodlight. The lux level and the timer can be set through knobs on the device itself. When added into a Z-Wave network, EH403 communicates directly with other end devices such as smart plugs, or to report directly to a Z-Wave controller (usually a gateway). It alerts the controller when motion is detected and through Z-Wave commands, the controller can remotely turn on/off the floodlight at any time and be able to configure its lux level and timer setting. This product supports the S2 security protocol that uses encrypted Z-Wave Plus messages to communicate to other security-enabled Z-Wave Plus products. A security-enabled Z-Wave Plus Controller must be used in order to fully utilize the security features of this product.
