Small cheap status indicator

[cehahe5692]

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?

If your Raspberry Pi is in the location you also want to show the LEDs, then the cheapest option is connecting a few LEDs and resistors to the Raspberry Pi and controlling them via GPIO. Schema and tutorials available on-line.

And then read to Wiki to learn how to control them from Domoticz.

Choose ESP 8266 or ESP 32, fit it in a small case, drill holes in it for the LEDs to peep through and there you go.
Domoticz communicates with your ESP which lights up the LEDs.

Here is an example for blinking LEDs to indicate power return to the net using an ESP2866

    logging = {
        --LOG_INFO, domoticz.LOG_MODULE_EXEC_INFO, domoticz.LOG_DEBUG or domoticz.LOG_ERROR
        level = domoticz.LOG_ERROR, domoticz.LOG_INFO, -- domoticz.LOG_DEBUG for debug, to domoticz.LOG_ERROR when all OK
        marker = "Teruglevering"
    },

-- between 30 minutes after sunrise and 20 minutes before sunset'

    --LOG level: This is the log level you want for this script. Can be domoticz.LOG_INFO, domoticz.LOG_MODULE_EXEC_INFO, domoticz.LOG_DEBUG or domoticz.LOG_ERROR
    --marker: A string that is prefixed before each log message. That way you can easily create a filter in the Domoticz log to see just these messages.

        local power_delivery = dz.devices(P1).usageDelivered

          -- groene led en rode led aan  
          dz.devices(LED_opbrengst).switchOn() 
          dz.devices(LED_gebruik).switchOn()  --

In Domoticz you have to create a (dummy) switch which switches the ESP8222.
The command is given to an ESP8266 running ESPEasy.

You can create your status indicator in a similar way.
