Domoticz

I am looking for a small cheap status indicator to work with Domoticz (either 433, hue or API). This could be a small led light, an e-ink label, or anything else that will work

I want to know the status of a bunch (4) of windows. If they're closed or open. In my imagination, I see 4 red LEDs that turn on when the status of a switch in Domoticz is set to 'on", meaning the sensor sees that this window is open, and 4 green LEDs that turn on when the status of that switch is OFF.

But of course, there are many other solutions I guess, or actually hope. Does anyone know a small cheap status indicator that works with my Domoticz?

You could use an old smartphone with only wifi connection and show domoticz web widgets of those 4 switches.

DomBusTH has a RGW led that can be used as statuses notification.
It's not exactly what you need, but you can use each led as a stupid ON/OFF, or using it to notify a stutus (1 flash, 2 flashes, 3 flashes, ...)
Check the video example showing how to use LEDs to show how much power is imported or exported to the grid.


You can do the same activating the red LED to emit 1 flash (window 1 open), 2 flashes (window 2 open), 3 flashes (windows 1 and 2 are open), and so on, as a binary format.
It also has temperature+humidity sensor and 6 I/Os that can be connected to magnetic contact sensors (to know door/window status).
To use it with Domoticz, just install the DomBus plugin (from Python Plugin Manager or from github) and connect each module by a alarm cable (4x0.22mm² wires): every time you connect a new module, Domoticz automatically recognize it.

You can also make your own OLED display with ESPEASY (or another ESP library) over wifi like https://www.letscontrolit.com/wiki/inde ... LEDDisplay

From Domoticz have a dzvents script push the state of those four switches to the display.
