I’ve been reading a lot in the past week about smart home and SmartThings, but since I don’t have any of those smart hubs with me yet, there is no way for me to be very sure of whether this is the right thing I should get.
Before getting into the actual scenarios, there is a bigger problem that I need an answer for.
My family is moving to a new 5-floor concrete house (Ground, 1, 2, 3, and Root for easy referencing). The router will be on level 3 and a WIFI extender/hotspot will be used to ensure WIFI coverage for all 5 floors. The question is, would z-wave or zigbee protocol provide enough coverage to control sensors/devices on G floor, or must I rely on WIFI and only WIFI? There is reinforced concrete between the floors. Is there any sort of signal extender for those protocols?
Then about the functionality of the SmartThings hub. Unlike many other users, I do not intend to control anything at all, but I’d rather to preset all the automation rules and let the things control themselves for me. To me, a smart home is the one that can think and act by itself, not the one to receive orders and execute them.
The only time that I will pull out the app on my phone is to set the house to “Sleep” mode to activate even more preset rules (I guess there’s no inexpensive way to let the house know that I’m about to sleep other than touching an icon in the app).
The rules I have in mind are not rocket science, they’re just like:
Auto on/off the lights along the corridor and staircases at night when someone is using them. Motion sensors may be used here and I guess this can be done by a few shortcut groups, one for each corridor/staircase. Correct me if I’m wrong.
Auto on the bathroom light when some one walk in, keep the light on while they’re doing their things (note that people may not move at all while doing certain thing), and auto off when the person walks out and close the door. Still don’t know what to use here yet (motion sensor or door open/close sensor, or both). If using door sensor, it may not work properly if the person does not close the door (i.e. to wash hands only), or if the door is open and close again but the person is still inside, for whatever reason. If I can do this, I can do the same thing for the kitchen and the study room as well.
When I turn on my PS4, the TV should be on as well (haha, this crazy idea just pop out)
The air conditioner auto off at 4am and the fan auto turn on to take over the job. Well I may need a thermostat and a smart plug for this but they added up would be even more expensive than the hub itself. Is there any cheaper way?
When I change the mode to “Sleep”, the app should warns me if there is any window left open or if the Roof door isn’t locked,
While in “Sleep” mode, trigger an alarm on my phone when unexpected motion is detected on G or R floors. By alarm I mean something that can wake me up at night instead of just a push notification or an email. I initially thought of a siren, but that may wake up the whole neighborhood for a false alarm which is not nice at all.
Have two buttons on Ground and Root floors for my family member to press to temporarily pause the alarm mode if they need to access the motion monitored zone, during the “Sleep” mode, then press again to unpause it. This is because my parents do not use smartphone.
Well I only need to know if the above are achievable at all, even with custom coding.
Thank you in advance for all constructive replies.
