Prana recuperators (fan) for Home Assistant

ha-prana's Issues

Only entity is showing and not the Device

SHould it show also an device in HA?
I only have Entity present with somehow limited fucntions.

I am actually tring to automate a variable speed. for exaple 5in -1 out speed. But I don't see any possibility of doing this.
I also can't turn on heating

Upgrading to a new version of Python in HA 2022.7

The plugin stopped working in the new version of Home Assistant (2022.7) on HasOs.I think the reason for this is the switch to the new version of Python.

Issues on HA running on RaspberryPi4

Hi @alextud
can you tell me what I'm doing wrong? I've followed your indication and I was able to see the fan but I have only four entities:

list of the command codes for remote buttons

is there a list with all the codes corresponding to the buttons on the remote?

I have noticed that esphome has implemented the possibility to send bluetooth commands using an esp32 and was wondering if it was possible to use that as a remote from homeassistant.

Does it still work with current HA?

I have tried to install it with HACS on current version and when I try to add the integration I get an error.
After I have the error, the integration is not visible in the list anymore. I cannot try to add it again. However I can find the Prana Recuperator.. CO2, Speed under Entities but cannot d anything with them.

I also tried to Downgrade HA core to an older version(2021.7.1), but I cannot even get the integration to show up in the list?

Any advice?
I have Prana 200C Pemium

how to set speed in and out

Hello,
I have setup your integration and it is working ok-ish with HA. I am having some issues though:

Check out the attached picture. If I want to set the fan direction for both in and out it is not working. Only In or Out. Also how would I go about setting one speed for In and another for Out?

Another question, if you don't mind: how do I access these parameters from within HA in an automation. For example if I want to set the fan speed to 2 and direction In and speed 1 for direction Out at a certain time and run for say 30 mins then switch off.
Where can I access these?

Thank you and keep up the good work!

some questions

Hi,
I also have a recuperator (prana-150, not premium) (no sensors). The ios app partially works. I tried your component.
in app only these features are available:

• power on/off
• speed setting (speed list: 1-10) (in out and together)
• winter mode can be switched (thaw_on)
• heater mode can be switched (heater_on)
• off timer
• display brightness

your program handles it well:

• speed query
• speed_in query
• speed_out query
• speed_in&out query (I do not fully understand this, it gives a value)
• winter mode query (thaw_on)
• heating mode query (heater_on)

it does not exist

• co2
• voc
• direction
• auto_mode
• night_mode
• air_in
• air_out

(night mode = speed 1 (low)) (not a separate mode)
(auto mode cannot be switched - or I couldn't find a way :)) because of this: speed_list: off, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Unfortunately I failed to control, the server is far enough away from the recuperator and I get quite a few communication errors. I'm trying to bridge the problem somehow. Don't have an idea to extend bluetooth?

Thanks,

Laszlo

Bluetooth proxy

Hi,
I'm using the latest HA. The bluetooth proxy also works with esphome and shelly. Unfortunately, prana is far from my server. With shelly, you can choose active or passive mode. Could the integration be made to work through a proxy?
Thanks!

Home Assistant OS installation

Hello,
I'm trying to make integrate prana 150 fans into Home Assistant, but can't figure out how to make it work.
I followed the Installation guidelines, but got the following error "prana integration doesn't exist".
Could you please make a bit more extended install guidelines?
I would really appreciate your answer, thanks!

Take over project

Hi there,

I tried using your custom component, however, it seems that it doesn't work with Bluetooth proxy. I am not a Python programmer, however, I've made a custom component for Prana that also uses Homeassitant config flow, has autodetection for Prana devices, and also works well with Bluetooth proxy. There are some areas that are not 100% working, however, for my use case it's working properly.

Would you be interested to take over the project I've created or use the code I've made to improve this extension? I do not have time to further develop it.

The code can be found at https://github.com/zauan/hassio-prana

Best regards,
Stefan

buffer size error

Hi,

Is Home assistant core installed.. maybe is not compatible?

A message handler raised an exception: unpack_from requires a buffer of at least 65 bytes for unpacking 2 bytes at offset 63 (actual buffer size is 15).

auto / night / heat mode

I can't change auto / night / heat mode unfortunately
there is only auto and manual preset mode

errors with connection

Hi,
it's the third time in two year that i install this custom component.

Now i see the status of the two prana but it is impossible to change the status.

the HA log show this:

is there something i can do to fix the issue?
Me and other users are open to finance the project in order to have a fully integration working.
Are you open for this? @alextud

Thanks
