Aeon Labs Nano Dimmer (zw111-a)

continuity (short) between COM and S1 seems wrong. COM+S1 has to be a sensor/input. If you accidentally wire L/line to S1 (as for some version maybe the NANO-SWITCH-not-dimmer that cannot handle it then I can imagine S1 being damaged.

otherwise you probably need to setup (external switch detection). This link is super-old so read the instructions with your hardware

Aeotec Nano Switch Wiring?

You’re absolutely correct in this case. The Nano Dimmer and Nano Switch have to external switch ports and both can react the same or be modified to directly control other devices directly through group association which depends on your configuration. Although S2 external switch port has an interesting setting for only 1 way triggers which is a slight difference in use between S1 and S2. I would just suggest connecting the switch to S1 and COM only if using one switch. @dan-dotson Most users will just use S1 to COM or S2 to COM connections for control over the Nano device. (Doesn’t specifically matter which S1 or S2 port you use, by default they both will control the load). The schematic shows 2 switch connections, both are completely optional for this unit. If only one switch is to be …

The diagram in the article is also confuisng since there is no COM.
