Newbie - HELP - what wall switches do I need

Using Z-wave in AU/NZ quickly becomes expensive though. There are not many approved mains powered devices in either Z-wave or Zigbee which is an issue for us. I would like to mention the Mercator Ikuu Zigbee range here. I have yet to be able to get my hands on any of their devices, but there are a few people here that have started using them. Have a look at this thread https://community.hubitat.com/t/mercator-ikuu. Will be cheaper than using Aeotec Z-wave inwall switches.
