Home Assistant 2023.3.6
Supervisor 2023.03.2
Operating System 9.5

I sussessfull added the device. Show 1 device and 25 entier.

Its respind on network ping, and unit is online and respond on Blauberg Vento mobile application.
Its not working true Home Assistant.

[gody01]

Thank You for report.

Can You please let me know:

• which verison of ecovent_v2 You have ?
• which version of firmware is on device

An if You can download https://github.com/gody01/pyEcoventV2 and in test.py change IP address of 10.94.0.106 to IP of Your fan.

Than run with python3 test.py and look at output of line with battery_voltage: 3258 mV

It looks, like Your fan does not report battery voltage with unit (mV) at the end. Perhaps they changed something in newer firmware version.

[Naustdal]

Hi and thank you for qick respond,

Version of ecovent_2" is: 0.9.2
Blauberg Vento Expert A50-1 S W - Found version 1.1.2, when connected with USB to fan.

I downloaded and added pyEcoventV2 to Home Assistant. Changed the ip adress in test.py and restarted.
I dosent know to to run python3 test.pyI, but should it not start automatic after restart ?

Got some new errors...

Attached some screenshot from phone:;

The fan has been setting up with use of USB and then connected to my local Wifi. Its have fixed ip adress and i can ping ti. Show fine and can controll it whit Blauberg app on phone.

[gody01]

test.py is not started by home assistant. This is comand line tool, which queries fans and prints results on screen.

In the first post, error is still the same:
voltage = int(self._fan.battery_voltage.split()[0])
AttributeError: 'int' object has no attribute 'split'

This means, that result from fan is not in format 2350 mV as in my fans, but only number.

In second post, it could be, thatn pyEcovent in custom_components breaks sometging. Better to remove.

test.py can be invoked on any computer with python installed not necessary on HomeAssistant.

On phone App, can You select Firmware option and post what it print on the screen.

A have:
Firmware version: 0.4
Firmware date: 20/12/2019

[Naustdal]

Ok :)

On phone app, im only getting app version as 2.1.6, nothing about firmware.. But as mention, i got version 1.1.2, when connected with USB to fan and used software.

From manual, i cant find anything about battery, not eather inclued in SmartHome manual.
VENTO Expert A50-1 W usermanual: https://blaubergventilatoren.de/en/download/6739
SmartHome manual: https://blaubergventilatoren.de/en/download/6815

[gody01]

Oh. Those manuals are not for V2 versions.

Perhaps You should try this one:
https://github.com/aglehmann/home_assistant_ecovent

[gody01]

Or maybe this one could work for You:

https://www.dingus.dk/dukaone-ventilation-with-heat-exchanger-and-home-assistant/

[Naustdal]

Thank you.
dukaone; I dosent understand how to impliment the fan.. This code isent my strongest side..

[gody01]

I suspect, that https://github.com/aglehmann/home_assistant_ecovent could support Your Vento, since it is for earlier version of fans.

[sfrevel]

Just have a look at my comment here - this split error looks really the same to me - so double check you pin/password of the device you want to initialize!

I have added the Raumluft Oxxify Smart 50 which is pretty much the same fan device - it has just an other device id. And the fans work with this integration. But I installed the HA custom component manually and als the ecoventV2 library. So there are some small changes to the code in my environment to load the library from the custom component directory off HA.
