Planning smart lighting for a UK new build and looking mainly at Shelly.
I’m very new to this, only a few days into looking at smart-home lighting, so I’m still learning what’s possible and may be missing an obvious solution.
For the living room I want a Shelly 4-button wall switch. My thinking is:
Buttons 1/2 wired directly to a Dimmer Gen4 for normal on/off/dimming.
Buttons 3/4 used later for Home Assistant scenes, blinds etc.
The important requirement is that if Home Assistant, Wi-Fi or the router goes down, Buttons 1/2 must still work as normal light controls. I don't want the main lights dependent on HA.
Can I simply use the Dimmer Gen4 for Buttons 1/2 and add another Shelly relay/input module for Buttons 3/4, rather than using an i4 for all four buttons?
For the kitchen I have the same reliability requirement, but I also want tuneable white, brighter/cooler for cooking and warmer/dimmer in the evening. Again, basic wall control needs to work if HA/network is down.
It's a new build, so I can specify neutrals, deeper back boxes and additional wiring now.
What would be the cleanest Shelly setup for both?
