Documentation: wiring cmt2300a esp32 devkit #998

maybe that is important too. I have used the self compiled current hms branch. |
|
that branch is not updated any more, please use |
|
@lumapu - thanks for your advice, I have moved to develeopment branch shortly after I having started my question. But this is not an answer to my question. I am looking for a wiring diagram for solely having a CMT2300A connected to the ESP - idealy I would like to have an advice how to config this inside the software. Thanks |

Hello |
|
Have you checked the issue #904?
|
|
I'm not doing well, could I write a call? |
|
@lumapu |
|
I did a quote on the interesting part, the pinning. Ahoy will support both generations, it depends on your settings which module will be used. @mirek-z do you need a translation of my post before? |
|
definitely yes, because the soft has CSB, FCSB and IRQ settings and CMT has SCLK SDIO CSB FCSB, how to set it in the soft? |
|
Same Problem here. CMT: nrf: GPIO4 - CE However, I cannot bring the NRF to work: "your NRF24 module can't be reached, check the wiring, pinout and enable" CMT says: And I am not sure what to select for IRQ of the CMT. Nils |
|
for the CMT part I use the following pinout with an ESP32-30 Pin module: SDIO has to be connected to D23-VSPI-MOSI and cannot be placed somewhere else. Same for SLCK, it has to be connected to D18-VSPI-SCK For IRQ (Interrupt Request) you need a interrupt capable pin of you ESP, I use D34 for that. For NRF (optional) you can use the following pins: for CS, CE and IRQ you have free choice. |
|
I have it exactly as described, but in the console I have it all the time: i only have cmt 2300 and esp32 module. I am trying to connect to HMS-2000 4T |
|
and shouldn't the microinverter be disconnected from the dtu? or something? wires well connected and no contact with hms |
|
would be nice if you post the serial output from booting up Ahoy |
|
|
I meant the log during boot up - once the CMT module was initialized. I think the ESP can't communicate with your radio |
|
|
sieht eigentlich gut aus, weiß nicht wo es hakt. |
|
maybe from the beginning. |
|
your pinnumbering is wrong, check https://www.studiopieters.nl/esp32-pinout/ |

@jmeister79 did you make it work ? I have ebay board which have same configuration(OpenDTU pinout): Im set this setting: But can't test it because still waiting inverter... When Im insert some serial of HMS inverter and check console I get this: |

I switched to opendtu

@lumapu I use an HMS microinverter and an Ebyte E49 900M20S chip My Trial : |

i have desolderd the Nrf modul now it workes fine |

As @mo0815 statet after removing the NRF modul it seams to be working - i believe it is a problem with either the poor quality modul or the power supply or both of them. I have done a couple dozend of opendtus and from my expieriences its always a problem with either cheap NRF modules or more often poor powersupplies. Most of my problems were solved when using a reliable and proven capable power supply. If that does not helped, the problem was typically a cheap chinese rebuild of an NRF module. Mostly they are functioning in general but have difficulties to establish a reliable radio signal which mostly ends up in (at least) unstable function. After using good quality power supply and spending some bucks more per NRF modul these problems never come up again. When following this simple rules you will see that opendtu is a very stable and reliable project. |

I am looking for a wiring diagram to connect a cmt2300a to a esp32 devkit. I want to connect solely a cmt21300a (no nrf24l01+). Connecting the csb and fscb is straight forward but where is irq connected to. As the systems settings have solely 3 input fields (csb, fcsb, irq) where to connect the sclk ping of the cmt2300a.
Right now I am getting constantly something like:
