I don’t know - a nanoCUL is only about £25!

BTW, the CLI to use is actually: tail -f /dev/ttyUSB0

dariusz · October 20, 2020, 7:10am

Maybe I investigated that - at 06:45 I have back-up running on the ‘proxmox’ machine. In ‘stop’ mode…
Looks like this is the reason… I’ll change to ‘snapshot’ mode and see result…
But the general question remain - why ‘evohome_cc’ is not returning to normal, operating mode when the ‘hassio’ was stop and restarted…???

backup

scstraus · October 20, 2020, 12:52pm

The /dev/ttyUSB0 never even appears. Dmesg has the only trace of the device that I can find, unless it ends up as a ttyS device…

hamba · October 20, 2020, 3:25pm

you need to install the linux-firmware package for debian to load the firmware for the HGI-80

I think you need to do an apt-get install firmware-linux-nonfree
In your sources.list make sure you have added contrib non-free and done an apt-get update

If you are on a raspberry pi the firmware isn’t in the package for some reason and and you download it from here
wget http://anduin.linuxfromscratch.org/BLFS/linux-firmware/ti_3410.fw and move it to /lib/firmware/ti_3410.fw and reboot.

That should get you a /dev/ttyUSB0

dariusz · October 20, 2020, 7:03pm

This is strange… I tested HGI80 with ‘Debian’ and it worked without problems…

scstraus · October 20, 2020, 9:44pm

Hmm, it’s weird. Because I looked and ti_3410.fw and 5052.fw were both in the firmware directory already. I assumed it was the

ti_usb-v10ac-p0102.fw

that’s missing, but I can’t find that one anywhere. If other people have gotten it to work on Debian than it’s really weird… Does the HGI-80 have a special USB cable? I switched out the USB cable and got rid of a bunch of different printer cables when I was doing my migration… Didn’t think it would make any difference.

I guess I can try the linux-firmware package, but I looked inside the package and also couldn’t find the ti_usb-v10ac-p0102.fw file, and since I have the other ones already, should it change anything? Did this work for you?

dariusz · October 21, 2020, 5:23am

Please see my ‘firmware’ directory in Debian 10.6 - nothing special…
And with this I can collect data from /dev/ttyUSB0 => HGI80.
I’m sure I was not installing any special fimware to support ‘ti_3410’…

Cinamon · October 21, 2020, 8:44am

@zxdavb can you also add the option to set setpoints? The same as in the “standard” evohome component? Or isn’t this usefull when i remove the wall controller/display?

zxdavb · October 21, 2020, 9:45am

@Cinamon Changing setpoints of evohome zones is already supported: you use the climate entity in HA (either via the web UI, or the climate.set_temperature service).

scstraus · October 21, 2020, 6:10pm

The interesting stuff would be in

/usr/lib/modules/4.19.0-11-amd64/kernel/drivers/usb/serial/

As it appears this one needs a kernel module. In there I have

ti_usb_3410_5052.ko

but not anything resembling

ti_usb-v10ac-p0102

I’m going to set up my old ubuntu server again and try it on that and see if it still works to ensure it’s not just a cable problem. Any chance you could show me a dmesg of what yours looks like when you plug it in?

Does anyone recall if I need to press the button on the HGI-80 to get it to register or something? Is there a light on the unit that should come on?

dariusz · October 22, 2020, 10:54am

I’m out of my home for few days… So I can not plug and un-plug… But see screens what I could get…

P.S. The light/switch on HGI80 has no meaning. It is only for binding with ‘evohome’ system…

dariusz · October 22, 2020, 11:15am

Some update - I noticed when I run on ‘Debian’ commands related to USB port, the USB device is disconnected from ‘hassio’ and behaves not stable…
In my case ‘Debian’ and ‘hassio’ are on the same machine…

freekeys · October 22, 2020, 8:38pm

Thanks for all your work on this! Finally got my nanoCUL and am excited to get started. Just to check, any reason why I can’t load the evohome_cc custom component through HACS as a custom repository?

zxdavb · October 22, 2020, 10:13pm

It is not in HACS as yet - too unstable

freekeys · October 23, 2020, 7:31am

Yes makes sense, but as I understand it individual users can add repos to their individual HACS to automate the git installing/updating… would this be an option here? https://hacs.xyz/docs/faq/custom_repositories

davidtja · October 23, 2020, 8:32am

I’ve purchased the Nanocul but too inexperienced as yet to test this perhaps it could go to HACS when David feels it’s ready to be released to less techy users?

freekeys · October 23, 2020, 9:02am

So I’m not advocating that it goes to the main HACS store yet (for wider audience) at all - just that we explore using the HACS “custom repositories” feature as an easier install/update route for individuals / early adopters at this point. Just checking in here to see if there’s any reason why this couldn’t happen at this stage.

The linked HACS documentation above says “WARNING: Not all repositories will work in HACS, since HACS still needs the repository to have a known structure.” But I’m not sure what this means exactly.

EDIT: I tried adding it and got “Repostitory structure for master is not compliant”. I’ll have a look into what would be required

freekeys · October 23, 2020, 9:16am

Okay here are the requirements (link below) - would this be a major change @zxdavb ? My assumption is it would make installation / upgrades a lot easier (but I may be missing something).

ivovangastel · October 23, 2020, 11:45am

@zxdavb,
i have release 0.4.3 up and running since a few days. all sensors are available.
are there any specific tests you would like me to do?
is there a format you like to recieve the logs (txt, excel)?
i have 8 HR91 in 7 zones, evotouch color and opentherm boiler relais.
