I had create a public share link for my calender in Nextcloud in order to use it with MM. That’s an info I have not found anywhere. My config looks like this:

               {
                        module: "calendar",
                        header: "Upcoming Birthdays",
                        position: "top_left",
                        config: {
                                timeFormat: 'absolute',
                                urgency: 0,
                                getRelative: 0,
                                showEnd: false,
                                dateFormat: 'Do MMM',
                                fullDayEventDateFormat: 'Do MMM',
                                calendars: [
                                                {
                                                symbol: "calendar",
                                                url: "https://User:Password@your_url/remote.php/dav/public-calendars/xxxxxxxxxxxxx?export",
                                                },
                                           ],
                        titleReplace: {
                                "Upcoming Birthdays": "",
                                },

This is finally working for me after trying all possible URL methods before.

I use a 12V power supply for the LCD screen. From the 12V power supply I have a step-down module which takes the 12V and puts 5V out for the Raspberry Pi. It runs perfectly fine for almost 5 years now.

$4999 Holy sh!t…!

Well, thanks for your feedback. That’s very useful.

@Feelm I use very cheap universal LCD controller boards from AliExpress. A few years back I ordered a couple of TSUM V.56 controller boards to use with old laptop displays. The panel for my mirror is from a broken 24" FHD display which I got for free.
The boards have a 30-Pin LVDS interface and multiple outputs, like HDMI, VGA, S-VIDEO. They allow DVB-T but it isn’t working where I live since we switched to DVB-T2HD a while back.

Back in the days they cost around 10 bucks including cables and shipping to Germany. No idea how it is these days.

The boards are programmed via USB. You just load the file for your panel onto a USB drive and flash the firmware of the board. Easy-peasy…

There are also plenty of other boards you can buy but those are usually not to be flashed by yourself. They need an extra programmer which costs more than a controller board.

There are also some MT6820-B controller boards in my drawers which only support VGA out and are configured by jumpers.

@Feelm Both panels are 2-Channel 8-bit and should therefore be compatible.

I am not sure if I understood correctly but those PINs are for a I2C EEPROM which contains the display timings for the panel. However, your controller board is most likely not designed to check for the timings and just assumes them. Hence the missing PINs on your old panel.

I’d say the new panel works without any issues. I generally use programmable controller boards. Not sure what difference this makes.

Please report back if you go ahead and buy the panel.

@andi-aw-weiss said in {HowTo} turn on/off your monitor (Time based, PIR/Button, App):

The change quote: “io.output(RELAY_PIN, False)” and for monitor off “io.output(RELAY_PIN, True)” only causes the relay to work in reverse. I now use this script:

Are you saying the screen turns off when the PIR detects a motion? In that case you have to change the the terminals on the relay. You have three terminals to connect the wires to. GND, normal open and normal close.

Another note: I have a bunch of relays here that are supposed to be compatibles with Raspberry Pi’s but somehow they don’t properly work. They switch exactly once and then are stuck. Not sure if you’re having the same issues.

@andi-aw-weiss I think you are using the wrong script. With just a quick look it seems you’re running the script from point 2.2 (Using PIR script) of the first post. What you want is point 5.2 (Use relay with a PIR). That script used in 5.2 is different than that of 2.2, which does not have code to control the relay.

Have a look at it again.

@besiece Your panel uses an eDP interface. You can find universal eDP controller boards with the usual suspects, such as Aliexpress or Ebay. I don’t know how the touch interface is controlled. The datasheet for that panel doesn’t mention touch at all. If it is via a second 4- or 5-pin connector it’s possibly USB.

I have not yet dealt with eDP displays. My experience is with LVDS panels only.

@farhad said in Unsure of which LCD controller board to buy:

SU6C12H10AS01X

Can you post pictures from the backside of the LCD panel. Make sure all labels are readable.
If I google for SU6C12H10AS01X I only get info about the Toughbook, nothing about the LCD panel.

@sdetweil I have to admit I don’t follow every post anymore. I’ve build my mirror like 3 years ago and it’s working the same way it was build ever since. The relay/scripts solution just works without any issues.
So it seems the CEC solution is good for the Pi4 but on a Pi3 the relay solution is better.
