I’m looking for generic Zigbee cheaper alternatives to this: Philips Hue Smart Wall Switch Module [https://amzn.eu/d/av9X5Gm](https://Philips Hue Smart Wall Switch Module)
It’s a battery powered in-wall module that connects to your existing switch hardware while the mains lighting is hard wired, so always on. Switching of the bulbs is then handled programmatically or based on flipping the existing wall switch
Thanks.
