I’ve been told that after many reliable years of operation my AlertMe system is to be discontinued, I’ve got some questions about Smartthings, which looks the closest of all the hub alternatives.
Can Smartthings control and respond to AlertMe units? Or am I going to have to replace all this kit.
Are the zigbee sensors the same in the UK and US - I’m moving to the US so will eventually want as much as possible to work in the US.
Is there a PC based API, where I can control the devices locally without needing the internet.
Currently my AlertMe system relies on them to control lights and the security alarm, but when no-one is at home, it switches to an automatic system to turn lights on and off. I’m wondering can I use Smartthings to at least replicate some of this functionality.
That’s a whole series of independent questions, and I’m feeling rather tired, so I’m going to have to leave most of the details to other people.
The first big point is that while zigbee is the same everywhere, it also allows for different “profiles” including manufacturer proprietary profiles, and devices of different profiles cannot talk to each other. SmartThings uses the “zigbee home automation” profile, ZHA. So the first step is to find out exactly what profile the alert me devices are using. It’s not original issue, but there still might be incompatibility.
Next, smartthings is mostly a cloud – based system. Most actions require that you have an active Internet connection. The exception is the official “smart lighting” feature, and then only with some specific devices. So even if you can write custom code which allows you to integrate the alert me sensors with the smart things hub, just the fact that it’s custom code means that it will not be able to run locally.
Right now routines do not run locally, custom code does not run locally, you cannot arm or disarm the security portion of the system locally, and the mobile app cannot talk to the hub even if they are on the same LAN– – the app talks to the cloud and the cloud talks to the hub. ( technically, it doesn’t have to be that way, but the fact is it is that way in the smart things platform.)
If you are looking for a locally operated security system, SmartThings is probably not going to be a match for you. You can find much discussion of this in the forums.
Thanks for the rapid response, it seems that I can’t do what I want with Smartthings, so I guess I’ll have to programme my own solution. With Alertme I’ve used local control only for lights when the house isn’t occupied, but this is fundamental to my security system.
If you choose exactly the right light switches, you can set some things up to run locally with SmartThings, but the house can’t know whether it’s “occupied” or not because the Geopresence piece depends on the cloud.
There are a number of other options available, and every system has its own pluses and minuses, so you just have to see which one best matches your own needs.
