You don’t say if you have any IoT networks yet, like zwave or zigbee, or if you’re looking for wifi. All have advantages / disadvantages, wifi is cheap and doesn’t use a separate dongle, zigbee devices tend to be cheaper, and a good variety available, Zwave is solid and doesn’t conflict with wifi or zigbee networks.
For the Hue bulbs you want a switch that lets you disconnect the relays from the physical switch. I don’t know what devices to suggest for EU, but my preference is to make the switches smart so they continue to do switch-like-things instead of having to retrain people.
