Orcon ventilation: 31D9 payload not recognized, wrong fan modes #45

maleadt · 2022-05-09T21:24:23Z

I'm looking into using this (awesome!) software with my Orcon HRC-350 (sold to me under the brand Ventiline) through an Arduino running evofw3, and am encountering a couple of issues.

The first is a payload that isn't recognized. When I set the ventilation fan speed to respectively away, 1, 2, 3, or auto, encoded as fan modes 0 to 4, my unit responds with a 31D9 message where the payload is simply either 00000000, 00000100, 00000200, 00000300 or 00000400. That doesn't match the regex in ramses.py, which seems to expect much more data:

This also shows that the fan modes are not mapped correctly: 0 is away, 1-3 match fan speed 1 to 3, and 4 should be auto (fan speed determined by air humidity).

The much more complicated 31DA packets are fully recognized though 🙂 The rendering in the CLI is cut off though (maybe it could drop fields that are known to be bogus for this model?):

Finally, I also encountered the following packet with a prompt to file an issue:

packet.log

zxdavb · 2022-05-10T23:10:23Z

The issue is that none of this protocol is documented.

I have updated the code, so that it can parse your packet log without error/warning. I will be dropping a refactored build soon.

The client.py is for ad-hoc, you can:

cat packet.log | python client.py parse > msg.out

I will reach out to you shortly, when I have capacity

maleadt · 2022-05-11T07:23:02Z

Thanks, confirmed that current master parses the vent_status messages now (although it decodes the fan mode as exhaust_fan_speed):

zxdavb · 2022-06-11T08:06:38Z

BTW, the fan modes may be wrong for your orcon-compatible HRU (or the 15RF), but they were OK for the system I had access to before (a Nuaire PIV)...

I think the way forward is to get it working with your system, then use the traits feature to provide fro any difference.

zxdavb · 2022-06-11T18:57:08Z

@maleadt The time has come to get remotes working... Please tell me the make/model of your remote

The latest version of the client.py has a new switch, -lf, which you may like.

zxdavb · 2022-06-11T19:32:51Z

@llevering could you tell me the exact make/model of your remote and your vent unit?

Or is it a fancy CO2 sensor?

maleadt · 2022-06-16T14:43:04Z

Please tell me the make/model of your remote

An Orcon 15RF (the device also mentions VMN-15LF01, 21800000, 2002, H6S9). The plain model, without CO2 sensor.

llevering · 2022-07-05T12:01:12Z

@zxdavb I thought I did reply earlier, but it seems I forget the sent my comment.

I have an Orcon 15RF simple remote like @maleadt the vent unit is a Orcon MVS 15RHB, with a humidity sensor. I upgraded to 20.9 today.

zxdavb · 2022-07-05T16:41:23Z

@llevering Can you confirm your remote does not have a CO2 sensor - it looks like it has one to me:

It also has a movement/presence sensor?

Or maybe that device isn't yours?

llevering · 2022-07-05T18:41:41Z

I can confirm it does not have a co2 sensor. There are versions that have one but it ours doesn't.
