Honeywell CH/DHW via RF - evohome, sundial, hometronics, chronotherm

ANSWER: For anyone who has HVAC:

For HVAC, you will have to add the following to your configuration, regardless of whether you enforce_known_list: true, or not:

 - 30:123456: {"class": "FAN"}  # Ventilation unit
 - 40:123456: {"class": "CO2"}  # CO2 sensor
 - 50:123456: {"class": "HUM"}  # Humidity sensor (indoor, relative humidity)
 - 60:123456: {"class": "SWI"}  # Boost/timer switch (2-way or 4-way)

You will need to do this, otherwise you get error messages like:

Unknown src type: 40:123456, is it HVAC?
Corrupt packet: Unknown src type: 40:123456
Corrupt packet: Invalid code for 30:123456 (RFG) to Tx: 31DA

I have an Itho Renova Tiepakket CVE (It’s written down on the itho box)

zxdavb · January 10, 2022, 2:33pm

What else do you have - switches, sensors, etc?

Cinamon · January 10, 2022, 3:06pm

Only a four button switch. Speed 1,2,3 and a timer button.

@cinnamon Your system if full of packets from your neighbours, and it - significantlt - presented a cognitive blind spot for me.

However, I now think this is your known devices list (you should confirm this for yourself):

     "known_list": {
        "01:087939": {"alias": "Controller"},
        "02:017205": {"alias": "Woonkamer (UFH controller)"},
        "04:023992": {"alias": "Kastenkamer"},
        "04:024000": {"alias": "Slaapkamer Nova"},
        "04:059569": {"alias": "Slaapkamer"},
        "04:225657": {"alias": "Toilet"},
        "04:225661": {"alias": "Badkamer"},
        "04:225663": {"alias": "Slaapkamer Evi"},
        "10:078099": {"alias": "Heating control"},
        "18:073736": {"alias": "Gateway (HGI80-compatible)"},
        "02:153425": {"class": "SWI", "alias": "Itho CVE RF Switch"},
        "20:007902": {"class": "FAN", "alias": "Itho CVE Fan"}
    },

The above is in JSON - it is pretty easy to translate into YAML.

Your must have the classes for the two HVAC devices.

I now have my HVAC C02 sensor showing and working, it’s in min(s) instead of ppm but is changing up and down.

guyank · January 10, 2022, 9:39pm

I’ve only just upgraded and have both of those but can’t work out what they are as their always in that state.

The new OT sensors triggered another thought. Would it be possible to control the state of the DHW keep warm on a combi boiler. I’ve seen it mentioned somewhere as a feature of OT, but that Honeywell have never implemented it.

zxdavb · January 10, 2022, 10:05pm

This appears to be a bug in HA - I will implement a workaround.

zxdavb · January 11, 2022, 12:32am

So, version 0.17.7 released.

The fault log binary sensor is live.

If you have HVAC - use this version, but make the correct changes to known_list first.

If you have OTB or UFH - use this version.

If you see a message like this:

Support the development of ramses_rf by reporting this packet

Please consider sending me a PM.

I did also update HA to 2021.12.9, in case it is related.

EDIT: Manually downgraded to 0.17.6 and it now looks better on start up, will know in 5 minutes. For anyone else, I had to downgrade manually as the 0.17.6 has been removed as release:

zxdavb · January 11, 2022, 8:35am

This issue is described in the release notes, no?

I am sorry I should have mentioned the breaking change in my post above as well…

restore_state: is now restore_cache:

evohome_cc:
  restore_cache: true

The release notes day:

The restore_state configuration parameter is now called restore_cache - the system will not start until you change (or remove) it.

I will make the above more obvious.

I am sorry, I don’t like creating breaking changes. However, they are considered changes and are done for good reasons.

In the above case, there is a plan to be able to restore state independently of the schema, in a future release.

iMiMx · January 11, 2022, 9:08am

My apologies, slap deserved for that one

zxdavb · January 11, 2022, 10:51am

The relevant code is:

def current_temperature(self) -> Optional[float]:
    temps = [z.temperature for z in self._device.zones if z.temperature is not None]
    return round(sum(temps) / len(temps), 1) if temps else None

I have not recently made any changes here, and - as you can see - it is a pretty resilient piece of code… So, I have no ideas…

Is this reproducible? Does HA start OK, or not? If it does start OK, with evohome_cc running OK does it disappear after a few minutes?

Do you have any zones beside TRV (radiator) zones?

phdelodder · January 11, 2022, 10:53am

Well I have the issue now that HGI80 is having issues today could be related

[ramses_rf.protocol.protocol] MsgTransport.write( W --- 18:000730 01:223036 --:------ 2349 007 017FFF00FFFFFF): no dispatcher

Think I need to restart the HGI80

zxdavb · January 11, 2022, 11:02am

This release is beta code - specifically: it may not play nice with a HGI80. The release notes say:

WARNING : this release may cause a HGI80 to exceed it’s duty cycle if you have an OTB - this is a WIP

Hello,

I have installed 0.17.7 and it seems to be working fine, but my ventillation and button to control the ventillation do not seem detected properly (the entities are created in HA but they are always unavailable).

My configuration is as follow:

And I have the following messages in my logs:

If you prefer I can send you a full packet.log, but I thought it might be easier for you to have just the relevant packets and to know what they correspond to on the remote.
Let me know if I can do anything else to help

Hello again,
I have noticed an error in my logs (with version 0.17.7 and latest version of HA):

Logger: homeassistant.components.sensor
Source: helpers/entity_platform.py:592
Integration: Sensor (documentation, issues)
First occurred: 2:04:45 PM (1 occurrences)
Last logged: 2:04:45 PM

Platform evohome_cc does not generate unique IDs. ID 02:024358-heat_demand already exists - ignoring sensor.02_024358_heat_demand

I have tried to delete or rename the existing sensor but it did not help. Restarting with restore_cache: "false"did not help either.

This does not prevent the system from working (i.e. I can still fake zone which is the most important to me) so do not spend too much time on this one, I’m just putting it here in case other people have similar errors.

Thanks again for your hard work

This is an easy fix - it has now been fixed). In any case, you can ignore this one.

This is outdoor_humidity (I am guessing) - I didn’t think anyone would have this. Can you confirm your HVAC tracks this?

This tells me you’re running 0.17.6 and not 0.17.7? In the latest version of the library, we have:

    _22F3: {  # switch_duration
        I_: r"^00[0-9A-F]{4}([0-9A-F]{8})?$",
    },

… you’ll see that your payload, 00023C03040000 will satisfy the latest regex, but not the old one.

…
