@Shinji0912 Hi, I wrote a module which converts messages received at serial interfaces to notifications (https://github.com/Tom-Hirschberger/MMM-Serial-Notifications). I have two Arduinos connected to my Pi with gesture and distance sensors.

My temperature module (https://github.com/Tom-Hirschberger/MMM-Temperature) can receive notifications to update the values.
Edit: The notification feature is only available in the development branch at the moment. I will mere it to the master the next days.
There are examples integrated which show how to connect an esp32 board with WiFi to get temperature and humidity.
Currently I am working on a module which should use MQTT to control an WS2801 LED Strip. But this one is in a very early state and will take a while to develop.

@Bugsounet Hi, thank you for your work. I checked the code, your notifications should work as planned. Play will start with the last station played or with the first one initially.

@Bugsounet Hi, great idea. At the moment my mirror is only controlled by sensors and touch.
The volume control buttons of my module only send an notification to MMM-Volume that’s way there isn’t any api in this module.
Everything else can be controlled by notifications. There is a small section about the notifications in the readme.

Hi,

just published an new version (0.0.3) which provides an autoplay feature. Simply add the station index you want to play to the config option “autoplay”. If you only configured one station it is 0. The station will start to play after about 1 second after the mirror started.

@bryan_1 Hi, currently there is no autoplay feature implemented. But I will check it the next days. Maybe it is not a big deal

@Hadr1en Hi, the module expects an json string as output of the script it executes. There is a section in the readme which shows an example:

{
   "humidity": 32.61236572265625,
   "temperature_c": 25.50150878906249, //Temperature in °C
   "temperature_f": 77.9027158203125, //Temperature in °F
   "error": false
}

What kind of error do you get?

@bibi I am using an Apds sensor with other sensors on a Arduino connected to the pi via serial interface. I documented it and wrote a universal module to receive messages on the serial interface. You can find my documentation at Examples

@elleclouds Black causes the display to turn off the backlight which saves energy. But it is surely less effective than switching the display to standby mode.

@kash Hi, I only get the white screen if my config is broken really badly.
Are you sure you added a “,” after the last module before the Gpio module?

Hi,
it depends on your monitor. Maybe there is an option in the monitor configuration menu.
If not you can configure the MMM-Screen-Powersave-Notification module to only hide all modules and show the black background instead of turning the hdmi off (hideInsteadShutoff option)
