One thing to note as far as the multi-click functionality is that it should be doable on the Blue series (Zigbee) switches based on what Eric shared here - Zigbee 2-1 Switch (On/Off & Dimmer) | Project New Horizon (Blue Series) - #202 by Eric_Inovelli
It’s not a option quite yet, but per that thread the current release target is March, and they won’t be dealing with the same supply issues as the red series with sourcing the Zwave chips. Still won’t have the LED bar for notifications if you go the Aux (or dumb switch) route, but if cost is a factor, then the Aux option will end up still giving you more than a dumb switch and should help with the user experience.
