The pi3 runs hotter than the pi2 (as the pi4 runs hotter than the pi3), it’ because of higher clocks and there fore more power usage that results in higher temps. The RAM issues I can’t explain however. (My Pi3+ runs at around 45-50C with a heatsink on the cpu.)

The Raspberry Pi 3's average SoC temperature unader load was 61C with a peak of 82C. Meanwhile, the Raspberry Pi 2 had an average temperature of 48.9C and a peak of 59.C

@s-monti-74 Don’t think there are any modules written for shelly yet. It’s not impossible but don’t think anyone have done it.

Same goes for the esp8266, don’t think there are any modules for temperature for those either.

@s-monti-74

zigbee does need a gateway since it talks on another protocoll than regular wifi (even if it is on the same bandwidth).

try building esp8266 nodes with temperature sensors and run espeasy on them. should cost you around 10-15usd each, without power supplies.
otherwise you have ready made Shelly Temp Sensors that runs on wifi, they are a bit pricey though.

you were missing a { after config: under the module currentweather

and also one to many , under the module weatherforecast

Corrected code :

		{
			module: "currentweather",
			position: "top_right",
			config: {   
				location: "",
				locationID: "53.9576",  //ID from http://bulk.openweathermap.org/sample/city.list.json.gz; unzip the gz file and find your city
				appid: "76b503a29647f3a01dd9ba1055daea6d",
			}
		},
		{
			module: "weatherforecast",
			position: "top_right",
			header: "Weather Forecast",
			config: {
				location: "",
				locationID: "53.9576",  //ID from http://bulk.openweathermap.org/sample/city.list.json.gz; unzip the gz file and find your city
				appid: "76b503a29647f3a01dd9ba1055daea6d",
			}
		},

@cyberphox Can you post your custom.css so we can see what you have done so far?

@mrdenmark it seems like there is no/limited pdf-viewing in the electron browser ;

https://github.com/electron/electron/issues/12337

So unless you convert the schedule to html or similar I guess it isn’t possible at the moment.

Skimming the issue thread there is java code that could possible do it if someone have the time to make it in to a module.

You have two unclosed brackets and a missing comma.

it should look like this :

        {
            module: 'MMM-Buienradar',
            position: 'top_left',
            config: {
              lat: 52.1015474,
              lon: 5.1758052,
              forecast: true,
              zoom: 1,
              interval: 10
            }
        },

not like this :

        {
            module: 'MMM-Buienradar',
            position: 'top_left',
            config: {
              lat: 52.1015474,
              lon: 5.1758052,
              forecast: true,
              zoom: 1,
              interval: 10
            }
        }
  ]        
}    

@ProtoBn then get a Pi3, they run a little bit cooler than the Pi4. And you should be able to find Pi3’s for cheap now that the Pi4 is out

@mosheva yeah, the MM2 is already a website.

Just open http://“your ip”:8080 in any web browser and it will display you magicmirror.

It requires that the mirror in the lobby is connected to the same network as your computer that is running MM2. Or that you open it up to the web (which I don’t recommend).

There are several ways you could send messages to the mirror without needing to alter the config-file at all.

@ProtoBn Regarding what Pi you want is pretty much depending on what you intend to run on it.

If you intend to primarily run text based information then any of the newish pi will do (2-4), but if you want to run animations, video etc etc the faster the better.

And you don’t really need a pi either, any type of computer that can run Linux will do the trick. (I think Windows is also an option).
