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

is config flow documented somewhere? it isn’t clear to me the benefit/why I want to take advantage of it. Thanks.

Upgraded to 0.41.7 from 0.31.6
All dashboards and automations are working as normal
love how all the entities are now showing under Ramses integration, especially the controller showing all the connected devices and then navigate to all asociated automations etc. Fantastic work

Any thoughts on the issues with the fans responsiveness to impersonated remote commands? The physical remote works without issue. Impersonated one unfortunately does has issues. This behavior started with 0.31.3 I believe.

Also still having a lot of these:

And these:

Lastly, any news on the HCF82? If you search for HCF82, there are apparently more people who are having issues with the entities of these thermostats not being instantiated in HA.

Received my SSM D2 today and updated to latest version.

All seems good and stable, temperature changes respond within a few seconds.

Just need to figure out how to fake the temp sensor for the main controller.
So i can move the evohome controller to the boiler room and use a tablet in the livingroom.

@zxdavb

how do i do this with the new version ?

known_list:
03:123456: {class: THM, faked: true}

returns a error in the config

Edit

I added the faked sensor to my rames.yaml and removed the intergration and rebooted it again.
Now the integration took my known list and added the faked sensor.

Now im strugling to bind the sensor to the controller

Please provide a packet log, if you want any help on this. Make it a 24h log, and I’ll try to address the other issues to.

and yet the UI shows:

03:123456:
class: THM
faked: true

Why not try this: 03:123456: {class: THM, faked: true}, or this:

03:123456:
  class: THM
  faked: true

I think this is saying it is already binding. Did you invoke the service call a second time before waiting for it to succeed/fail?

What is your system schema?

A couple of minor observations with 0.41.7:

I tried clearing the State and Schema caches via the UI to see how that worked. After submitting the configuration form to clear the cache there’s nothing in the UI to make it clear a restart is needed (unless I missed it).

After clearing the cache 4 of my Evohome zone devices picked up names of the form RAD 01:216136_0x instead of the zone name. Easy to change name and related entity ID’s in the UI of course. Just wondering what the behaviour would be on a new installation via Config Flow.

A restart is not needed - the integration is restarted in the background.

After the restart caused by clearing the cache, it has to collect 0004 packets - these contain the zone name.

By default it polls for these data only once every 6 hours…

This is a UX issue - please submit an issue to the github repo.

OK - I was expecting sensors to go “unavailable” initially after clearing the cache - maybe I didn’t wait long enough

Out of interest I tried removing the integration completely and re-installing 0.41.7 from scratch. It was not obvious how to get from installing the integration to the configuration UI stage - it didn’t appear in “Settings - Integrations”. I re-instated my ramses_cc YAML config, re-started and the config was imported as before. Maybe I missed a step there?

After a clean install all devices and and entities appeared as before, minor change to the zone device id’s from climate.ramses_cc_01_216136_0x previously to climate.01_216136_0x and similar for the controller and stored_hw. Zone names all appeared correct immediately.

Apart from not being clear to me how to get to the initial config without using YAML a clean install of 0.41.7 worked fine. Appreciate 0.41.7 is still “experimental”.

Yes i tried several times , same response

Here is my schema and known devices

I guess what I was saying was: what error message are you getting the first time?

The error message you have shown us, if when you trued a subsequent time - it is not useful.

You have not indicated if you have seen the expected messages (as shown in the wiki) in your packet log?

You need to press the Add integration button in the lower right and search for “RAMSES RF”. That is to say it’s not any different to adding any other integration for the first time.

I think I may have been having a dumb moment and used Search Integrations instead of using Add Integration

Im sorry , i probably had a dumb moment , it all worked out and is working as it should.

Thanks for your responses and time!
Appreciate the good and awesome work!

I have updated to 0.41.7 and very impressed thank you. Interestingly I’m still getting

even though I have commented out all the ramses_cc entries in configuration.yaml

Hi David,

First of all, awesome work on the integration!
I installed ramses_cc recently and I was wondering if the integration can impersonate a controller, or if I can use a round thermostat as a controller (less practical, since it is battery powered).
My goal is to change the round thermostat setpoint (as an ATC controller or rfg100 would do), but I’m not seeing how. Do you have any suggestions how I might get this working?

Currently I have a battery powered round thermostat (T87RF2025), an OpenTherm bridge (R8820) and a NanoCul (atmega328) running evofw3. I’m running ramses_cc 0.41.7 on HA OS on a Pi4.
I can see packets being sent between T87RF and bridge, and between Bridge and NanoCul. Also, I can see the thermostat and boiler entities with temperature, setpoint, modulation level, etc.
