[linoul]

I make v4.1 ebus-adapter to connect to the vaillant turboTEC pro, but the ebusd can't runing. where is the problem?

It looks like the adapter can't write to the bus

Hi @linoul , can you please make a video of the adapter after starting the scan and send to https://upload.danman.eu ? Let me know when uploaded.

[linoul]

Thanks for the reply, the video name ebusdscan.MP4 has been uploaded

[danielkucera]

This doesn't look like an adapter I have made:

Where did you get it from?

[linoul]

i made it from your project

[danielkucera]

Then some of the components has to be damaged - zener diode, transistor, ...

[21494]

I get similar problem but I have the adapter that you sent me.

I tried with different latencies up to 10000 ms, which is the maximum that allows me to configure

Thanks

[danielkucera]

Is your device supported by ebusd?

[21494]

I guess. I saw comments from people with the same model working with ebusd for example in this comment (https://github.com/john30/ebusd-configuration/issues/276#issue-1406832744) someone asks about the same model and thermostat that I have. In his case ebusd detects it as vaillant device. "arbitration lost" sounds like a hardware problem but I don't know...

[danielkucera]

Can you please try with the option --lograwdata ?

[21494]

According with https://cadlab.io/project/25252/master/circuit/d2lyaW5nLmtpY2FkX3NjaA%3D%3D

• I measured on the "TX-DISABLE" net in J2 and it is at ~2.1V even when blue led is ON. It should not be disabled to transmit?
• Eventually LED D5 lights up briefly 2 times every 5-10 seconds.
• LED D1 blink constantly.
• Voltage measured in the zener with multimeter is 0V.

Thanks for your help

[21494]

Ok, I have temporarily solved it by removing resistor R17 so that Tx is always enabled. Do you know why this may be happening?

[danielkucera]

Which HW version you have? Did you flash some firmware?

[21494]

I think the hw version is 4. and I flashed the last version I saw in releases: 4.2

[danielkucera]

which file exactly?

[21494]

-v3.0.bin I had doubts about which one to use

[danielkucera]

That's the problem. You need to use firmware.bin - that is for HW v4.0+ , I'll try to make it more obvious

[21494]

Jajaja ahh ok I'm going to restore the fix and update to the other firmware. I guess it will work. Thanks Daniel =)
