Lichten node/verklikker (photo out of date)

[OLIMEX PoE] gebaseerde node die kijkt naar de 3 AC netten van het licht.

Wiring and technical data

The 6 screw terminals are Optocoupler detect (2x3) of AC.

All 3 expect AC/230 volt. The RED led on the front is the 'AartLED'.

Code in [[1]]/

Current mac address is 3C:71:BF:10:62:A7 -- wired to the top patch panel, port 23. It is currently connected by a yellow cable to the top switch; port 23 (auto-negotiation, no further settings)

ESP32 PoE connector olimex

The AC voltage resistors/optocouplers have been moved out of the low voltage electronics box; and now reside in/behind the two light switches. With just 2 and 4 wires (gnd/E and signal/C of the optocouplers) going to the grey box.

White is the gnd, the colours (brown, orange, green) are the signal wires.

Furthermore GPIO 34 (was 5) has been wired to a 433 Mhz receiver - for our radio based mains-monitoring. As the digital out is 5volt - there is a simple 3k3/1k8 voltage divider to bring the signal to the 3v3 that the ESPs GPIO likes.

Building wiring

Note that the building wiring is a bit funny - an earth wire is used as a black-switch phase wire in the leftmost switch. Talk first to the trustees if you want to fix it - as this is a key part of building relative to the agreements made with the landlord.

Opto electronics

Wiring of the 3 opto couplers

Typical log

AC1 to AC3 are the OPTO couplers state; True is off (there is a pull up at work), False is AC voltage detected.
