I started my smart home automation 4-5 years ago. At which time, I updated the garage door opener, front door lock, thermostat, smoke detector, and about half of my home wall switches (2nd floor and basement). I was using the Simon XTI panel with Guardian Protection through alarm.com. All of the existing contact switches and motion are old school radio bases, not z-wave. I did end up doing 1 - 4 way (on the stairs), and 2 - 3-way switches (for a room) around the house
For better or worse, life got busy and end up stop working on its, up until recent COVID While looking through home-automation again, I was looking through Homeseer, Home assistant, and few others. In short, SmartThing 3.0 seems to hit most of what I needed to do, but may still go take a Home Assistant at a later time. As one concern I have with ST is that it is cloud base, so if my Internet would go down, I would assume I am screw I am technical but still green to the Z-wave protocol. One thing that stood out for me so far with ST is the ease of excluding and adding in a node (in most cases), and the recent tweak I find for the association. I tried that in the past with Aeotec Stick and it was a total pain.
I am in the process of replacing all of my radio-based sensors first (motion and door contacts). Probably going with ST contacts (even though it is zeebee) and EcoLink Motion. But one huge investment left for me are the remaining wall switches. Through out the years, few of my Evolve switches (master) went bad on me (15 %) , thank god I have some spare. But I do not have enough spare to finish the rest of the house. However, I do have over a dozen Evolve accessory switch (LTM-5) which I would like to use. I am not sure if it is right or wrong, probably more subjective than objective, I would probably using the same wiring method I been using where I will replace all of the switches to Z-wave, both the master and all of the accessory in a multi-way configuration. I just need to ensure that whatever brand I am going with will indeed
- Work with another accessory switch brand, as it seems GE will only with GE in terms of association.
- the travel wire with my multi-way configuration will always be hot on either end (Evolve did not have a dedicate traveler connection. So I end up capping the z-wave hot in, with the AC in, and the traveler together,)
