I know this is yet another thread for a hundred times answered question, but let me please ask again, because I am lost and confused in this particular topic.
I am in the process of designing our new house and I want it to be modern and smart. I´ve sat with my family and we´ve defined some core rules for the “smartness”. For lights, our rules dictate us, that we want them to be smart, but if something goes wrong, they need to work as dumb lights unless all electricity in the house goes off. We want to avoid a situation when some smart device (OH server, various hubs, etc.) goes wrong and no one is able to turn the light on and off (preferably when I am on a business trip so no one in the house is able to repair the malfunctioning part).
So, to lay down the requirements:
- There needs to be at least one light in every room, that can be turned on and off without the assistance of any other system or smart thing (simply only by the switch like “dumb” lights do). We called them “failsafe lights”.
- If all the components of the house are working properly, these “failsafe lights” needs to be part of the smart system, so they can be controlled via the in-wall switch, but also with the smart appliance (OH). When the in-wall switch is in OFF state, the smart appliance has to be able to turn the light ON. Also when the smart appliance is online and some scene or rule is set for “turn on event”, this event has to be triggered also by the turning the in-wall switch on.
- “Failsafe lights” should be controlled by wire.
- “Failsafe lights” have to have the ability to change the light temperature and should have the ability to change colors. It is enough to have the ability to control this feature only when the smart appliance is online and not via the in-wall switch.
- In addition to “failsafe lights” there can be other lights systems like Hue. These are obviously dependant on some single point of failure (e.g. hub), but it is ok.
- No vendor-lock in the system.
- It shouldn´t be pricey.
- All components need to be available on the central European market.
We have similar rules for other parts of the house, but only lights are where I am struggling and stepping on the same spot. I cannot find a solution that fulfills all the defined rules. I´ve rejected all solution that uses smart bulbs (eg. Hue) because they cannot operate without some hub. I am not a big fan of DALI or DMX - that seems too expensive for the job. I´ve found some dimmers, that are integrated behind the dumb switches and controlled over Zwawe network - it is not 100 % wired solution, but if the wireless fails, I can operate the light with the “dumb” switch.
Does anybody here successfully solved this task? I´ve read a lot on this forum about the lights and recommendation to build the system with fallback to “dumb” behavior when something goes wrong, but I cannot find any concrete design for that.
