Hi, I’m interested in replacing light switches and lights to zigbee smart switches and smart lights. I have the following questions that I would like to get clarified if possible.
-
I have brick walls and do not have neutral wires to the switches. This limits the options I may get from the market.
-
Since the switch sends power to the light, cutting the power off (or turning the switch off) will cut the power to the smart light and the light will be unavailable until the power is restored via the switch.
I am thinking about the following scenarios to mitigate this limitation by
-
jump the wires making sure the smart light is always getting power. Control will be done on the HA as a remote command. If the smart switch is capable of “decoupling mode” then this won’t be an issue and jumpering wires are not required.
-
If the switch is not supported in “decoupling mode” then wire the switch without any outputs to the smart light. The connection to the light is jumpered and will always get power and will be controlled via HA as a remote command. If the smart switch can be used as a remote control (no wires to the light bulb) this will help a lot by
A. Covering where the light switch is in the wall with nice looking smart wall switch B. Having the same functionality as a physical switch (well, it's just a remote and no direct connection to the light bulb)
Since I’m fairly new to home automation (I’m located in Australia), could someone please be able to verify the above thoughts and let me know if a smart switch can be used without connecting to a light and using it as a remote so the light and switch can be used at the same time?
Also, any recommneded zigbee switches that’s certified to use in Australia without the need of neutral wire and external capacitors? I found MOES swiches (some variants) does not need neutral wires and external capasitors but they do not have Australian certifications
