Reduced support for non-evohome controllers

Reduced support for non-evohome controllers

Schorsch99 opened this issue 3 years ago · comments

Hi zxdavb,

Maybe you can help me with this. I am getting some good decoded data, but also very many error messages (mainly "coding error" and "validation error"). Could this be something in my configuration/hardware, or is it code-related and the decoding of these specific messages is not fully implemented yet?

Here are a few examples:

Note this device sends a 1F09 packet:

Thanks for checking! :-)

Hello, I am sorry - most of my testing is on evohome. I should be able to sort this out... Could we start by you describing your setup? What controller/relay/zones?

Schorsch99 · Answer 2 · Fri May 28 2021 15:19:55 GMT+0800 (China Standard Time)

Hello,
no worries :-)
My "setup" is quite simple:

a cm67z as a 2-zone "controller"
four HR80 (I have a few more, but not installed yet)
I do have an additional Evohome Touch controller (the old version with monochrome display), but so far I only powered that up a few times for testing purposes.

David Bonnes · Answer 3 · Fri May 28 2021 16:40:58 GMT+0800 (China Standard Time)

The cm67m explains everything. It looks like a DTS92, but supports multiple zones.

It would be helpful for you to send me a 24h packet log, and I can dev/test against?

What device are you using to pick up packets?

Schorsch99 · Answer 4 · Fri May 28 2021 17:47:51 GMT+0800 (China Standard Time)

Took me a bit to figure out how to create a packet log :-)

Do you need a full 24h log? I'm getting several errors per minute, so an hour should contain about 120 - 240 of these packets.

I'm using evofw3 0.6.14 (Nano & CC1101) hooked up to a RPi4.

David Bonnes · Answer 5 · Fri May 28 2021 18:09:34 GMT+0800 (China Standard Time)

Evofw3 v7 is out and is strongly recommended.

24h log is better, but sent me whatever you can...

I've done no significant testing against a c67m, and
I won't be able to look at it for 12h anyway, and
previous experience has shown longer logs are best (but >2h would be OK)
some packets are sent less often, hourly, or once/24h

Even better, if you change modes/ set points, etc. During that time.

What is your relay?

Schorsch99 · Answer 6 · Fri May 28 2021 19:42:43 GMT+0800 (China Standard Time)

Thanks for the hint, I have now bumped it up to version 0.7.0 :-)

Log is restarted, I'll send you the results tomorrow. I will change some setpoints here and there :-)

I don't have a relay, only the CM67z and the HR80s.

David Bonnes · Answer 7 · Fri May 28 2021 20:41:51 GMT+0800 (China Standard Time)

Try:

python -O client.py -rr listen /dev/ttyUSB0 -o packet.log

David Bonnes · Answer 8 · Tue Jun 01 2021 05:57:10 GMT+0800 (China Standard Time)

So, the issue here is that the cm97z (which 'looks' like a DTS92, a thermostat) is acting a multi-zone controller (just like an evohome controller).

The evohome_rf library was always meant to deal with different types of controllers, but it has been almost exclusively written on & tested against evohome controllers.

Unfortunately, the cm97z may initially look like a thermostat, and only later on act like a controller...

I have tried to work out a way of automatically 'promoting' a device from being a thermostat to a controller, but I believe this will result is too many deep changes...

I had another solution already planned, but this is not imminent.

I will get rid of the parsing errors for now, and then see where we go next.

Thanks! Now I get no more error messages.
But the Terminal output (with the command above for generating packet logs) is truncated:

I don't know if these issues are related in any way.

But the Terminal output (with the command above for generating packet logs) is truncated:

This is normal behaviour - if you want to see it all pass the output though a pipe, or send it to a file.

Also gw_evohome_rf crashes immediately:

Seems like your schema is no correctly formatted?

David Bonnes · Answer 11 · Thu Jun 24 2021 15:51:26 GMT+0800 (China Standard Time)

Latest status (i.e. ramses_rf 0.10.0) - there remains little support for non-evohome controllers, despite improvements to the parser. This will be addressed in time.

Schorsch99 · Answer 12 · Thu Jun 24 2021 17:17:28 GMT+0800 (China Standard Time)

I understand that, but maybe you could help me with this: with the latest version I get the following error, even before the first signal (from the non-evohome controller) has been received:

From here on output is normal.

AttributeError: 'NoneType' object has no attribute 'encode'

This has been fixed - will be pushing an update soon.

Update works. Thanks! :-)
