RE: MQTT Daten vom Iobroker auf M5Stack Core darstellen.
@juergschwarz oh this ctu_0 or hiding labels is just additional project related stuff I needed at the time, not required for you to just display values subscribed by mqtt.

RE: MQTT Daten vom Iobroker auf M5Stack Core darstellen.
@juergschwarz said in MQTT Daten vom Iobroker auf M5Stack Core darstellen.:
Hallo alle
Ich versuche verzweifelt ein paar Daten von meinem Iobroker per MQTT zu beziehen und diese auf dem M5Stack Core darzustellen. Ich möchte das mit der UIFlow erledigen. Ich weiss, dass es mit einem Python Script funktioniert. (Habe mir per chatPGT ein solche erstellen lassen aber leider komm ich da mit der Darstellung und mehreren Datenpunkte nicht klar.
Also ich will das per Blockly haben in der UIFLOW Cloud.
Meine Datenpunkte sind:
Boilertemp: mqtt.0.ESP_Easy.Boiler.temperature
Kesseltemp: mqtt.0.ESP_Easy.KesselTemp.temperature
Vorlauftemp: mqtt.0.ESP_Easy.Vorlauf1.temperature
Welche Elemente benötige ich im Blockly für diese Abfragen?
In Python sieht das z.B. so aus:
// Subscribe to first data point
client.subscribe("mqtt.0.ESP_Easy.Boiler.temperature");
while (!client.available()) {
delay(1000);
}
Hab scho einiges mit dem Subscripe Element versucht. Leider ohne Erfolg.
Danke schonmal.Hi @juergschwarz , see below in blockly ...worked for me. My Setup was few esp-easy sending mqtt data to local mqtt server on raspberryPi, then M5 Core as data display subscribing to local mqtt.
Regards.
Rob.

RE: Wifi Connection Speed
how long it takes to connect if you burn firmware and set it up with network start for online UIflow? on my devices it usually connects in seconds

RE: M5Core - blank screen

RE: Forwarded Adafruit support for M5Stack Faces
@ajb2k3 said in Forwarded Adafruit support for M5Stack Faces:
Just curious, did you update the firmware between when it was working and when it stopped working? M5Stack do sell replacement screens for $30 ish as I had to check after braking the ribbon cable trying to replace the glass screen cover I accidentally broke putting in a screw that was too long.
Are you sure it’s soldered correctly?
Did you try running code that accidentally accessed the pins used by the screen?think you could get core2 for very close to this screen replacement price tag,

RE: Forwarded Adafruit support for M5Stack Faces
I have M5Stack Core Basic which after months and months of working fine suddenly is now only showing LCD backlight on after power is on. I can see its COM port fine, I can see COM port messages being printed fine, I can connect to it and load project via COM port or remotely via UIflow (wifi works) but......screen is blank with backlihgt LEDs on all the time...
You mentioned that you opened it, dismantled and soldered connections which would void warranty I think. Did you tried to ERASE it using M5Burner then load factory test easyloader in to it? -
RE: M5Core - blank screen
@ajb2k3 said in M5Core - blank screen:
Can you install the latest firmware version make you are using Core for the Core1 gen and Core2 for the Core2/touch gen as they have different screens and are connected differently
I'am loading Core firmware as below:
