Re: Monitoring and controlling - HOYMILES microinverters
Good!
Be careful, because json$ might return a "not found", resulting in a numeric value 0, if I'm not mistaken
Viel Erfolg und Spaß!

Re: Monitoring and controlling - HOYMILES microinverters
hi my code is nearly finishd - using a ILI9341 Display with an A-Z Touch Mod
added some Progressbars ,Monitoring the Inverter Power an the Grid Power- the control of the microinverter is still missing
@Helmut - take a look into the code it is easy to read ot the DTU -i think AHOY is similar to "openDTU"

this is the string you will get with:

these all strings so you can parse them

Re: Monitoring and controlling - HOYMILES microinverters
Hallo Ron,
wie kann man(n) die Leistung steuern? außer durch MQTT habe ich keinen Weg gefunden.
Das bedeutet aber, dass man ein Broker nutzen muss.
Ich nutze zwar IP-Symcon und kann das alles damit machen, hätte aber gern ein Wand-touch-Display.
Hatte schon mit Virtuinio IOT und Modbus TCP gearbeitet, jetzt mal mit ESP32
https://www.youtube.com/watch?v=CwgmrcxG7hQ
Hast Du da schon einen Ansatz?
Alles Gute
Hello Ron,
how can you control the performance? I haven't found a way other than through MQTT.
But that means you have to use a broker.
I use IP-Symcon and can do everything with it, but I would like a wall touch display.
Do you already have an approach?
Best regards, Helmut

Re: Monitoring and controlling - HOYMILES microinverters
Hello,
the "openDTuU or AHOY DTU communicate directly with the inverter - so you can not only receive data but also control certain values, for example the "Power Limit", so it is done and you don't need anything else
see this example :
https://selbstbau-pv.de/wissensbasis/nu ... steuerung/
If you have tested this successfully, let me know
have a nice Day

Re: Monitoring and controlling - HOYMILES microinverters
*annoyed...;
the ESP32 module - ESP32 dev Kit V4 - for the TFT display died again overnight - I noticed that it was very warm from the beginning an - this can be prevented by reducing the WIFI Power ?? ??? - Or has anyone already cooled the chip with a fan ??
it started with the fact that the get requests were no longer reliably processed - same as in the previous module
have a better Day

Re: Monitoring and controlling - HOYMILES microinverters
Is your ESP32 board damaged at the voltage regulator? Have you connected (too many) external devices (display etc.) to the internal 5V>3V3 regulator? This could be too much current or power dissipation for the regulator.[Local Link Removed for Guests] wrote: [Local Link Removed for Guests]Fri Oct 20, 2023 8:57 am *annoyed...;

I have noticed more and more 5V power supplies lately that actually have a 5V2 output, so a 1N4001 to reduce the voltage can also reduce the power to the 3V3 regulator.
Or you can use a separate power supply/ regulator.
A problem could also arise if 5V peripherals are connected to the only 3V3 tolerant (!) inputs of the ESP32

Re: Monitoring and controlling - HOYMILES microinverters
hi Peter,
i use this :https://www.az-delivery.de/products/az- ... VAQAvD_BwE
the Voltage at the 5V Pin ist exactly 4.994 V !
It is also remarkable: now that it no longer works, the ESP chip is only half as warm - but tomorrow I will receive new modules. then I will reduce the Wifi power first and see what comes - it worked well for a few days

Oh !!!
Would not have expected problems with the use of this board.
That is indeed annoying!
