I work with Levven Controls, and what they offer to home builders is smart home controls on every switch and light in the entire home during construction, but for less cost than traditional wiring. There are no wires going to switch boxes, so that labour and material cost savings is enough to offset the cost of smart controls.
I assume no wires means battery powered. How long do the batteries last? Will I need to replace the batteries in all my light switches every couple years?
Some wireless switches use the force of flipping the switch itself to power the transmission: kinetic light switches. That means you need to press a bit harder, but there’s no need to replace batteries.
They claim 10+ years. https://levven.com/products/consumer-wireless-switch-control... but I don't have any personal experience.
I know a couple of wireless X-10 switches I used to own lasted for a very long time. I'm not sure I ever replaced the batteries.
I have a similar system in my rented apartment, and there's no issue with batteries after 4 years so far.
I wouldn't choose it. Every ten pushes of the switch, nothing happens, and there's no visible / feelable state of the position of a switch.
The tactile feedback part of the switch is definitely an area we have tagged for improvement.
Batteries last 10 - 15 years with regular usage (30 on/offs a day). They use just a regular button cell battery.
Thanks! That seems pretty reasonable.
But of course the market for it doesn't care, and can pay for it.
I've thought about it similarly to you, but because of the labour cost of installation, it's an expensive job whatever the cost of the hardware/software, so there's not really a reason for installers to use HomeAssistant, OpenHAB, and the like. The difference will be thousands for hardware, on top of tens of thousands for the whole install job.
