The primary reason I bought my Smartthings hub (V2) a few years ago was for use as an inexpensive home alarm. Though I’ve expanded the system beyond that, it is still the most important feature to me.
Unfortunately I’ve been disappointed with the reliability of the Samsung multipurpose and motion sensors included (and subsequently purchased) with the hub. I find they go unavailable way too often to be reliable, the battery life is less than a year for all devices, and I get a lot of false alarms as the batteries are nearing death. In contrast, I have family with a professional alarm which was installed 3+ years ago; their sensors have been rock solid and they are still going strong on their original set of batteries.
Not sure why the Samsung sensors differ so much in performance from the pro alarm sensors (to be honest, I don’t know if they are nearly the same technology - I’m assuming they are). I’m not using any of the features beyond contact and motion (axis, temperature, etc.) if that’s part of the cause.
It got me wondering if any of those same devices would be available for use with Smartthings. Are there any “alarm-grade” devices available for use with our hub? Meaning, devices that are used with pro alarm systems, or ones with similar specs that will have the same reliability and battery life? Or other brands I should look at for greater reliability? Zigbee vs. z-wave? Contact and motion are all I need.
