I do not receive all the attributes in Home Assistant #54

Closed frodix closed 3 years ago

frodix commented 3 years ago

Hello, I am trying to use this project. I have an Altherma EHVX16S26CB9W.

I have a problem, my Home Assistant only receives the attributes that start with 0x00. The other attributes that start with 0x10, 0x11, 0x20 ... are not received through mqtt and they do not appear to me as attributes.

I’m using Esp32, and I have HA version core-2021.10.6 and Mosquitto broker version 6.0.1.

Sorry for my English but I'm using Google Translate, I'm from Spain.

what could be the problem?

Thank you!

The issue could be a bad connection. I had similar problems before I shortened my cable for example.

Hi @frodix, sorry for not replying earlier.

As @GO74 says, this can be an issue with your cable connection, especially the GND connection. Please check with new wires. Now also, there is an issue in you definition file. Try not to use the Default.h for your heatpump. ALTHERMA(LT_CA_CB_11-16KW).h would be more appropriate.

Keep us posted!

I had a similar issue (#51) and it turned out to be a bad grounding wiring as @raomin suggested.
I would check that first.

I also got a couple of timeouts when using too many parameters.

Hi,

I'm using ALTHERMA(LT_CA_CB_11-16KW).h but it still doesn't work. I have tried with various dupont cables but it doesn't work either, even exchanging Rx and Tx. The fact is that all my devices with those cables work for me. Do you still think that it may be because of the quality of the cables? Anyway I think I'm going to buy other thicker (24awg) and shorter (10cm) dupont cables. Thank you

Tell us one thing: how is powered your ESP32? If it is with a separate USB power supply, make sure to still connect the GND of the ESP32 to the one of the X10A port. Suerte ;)

Finally I tried with another esp32 and i already get data. Although some attributes like {0x20,0,105,2,1, "Outdoor air temp. (R1T)" or {0x21,0,105,2, -1, "INV primary current (A)"} I get 0. I guess it will be the fault of my machine. Thank you!

Yes indeed, some machines do not return the current consumption... Have fun!
