Upgraded broadlink to 0.6 using pip but I think hass is downgrading the broadlink component to 0.5 when it starts up from 0.6. Is there a way to prevent that (switch to hass-dev maybe?)

[MartinHjelmare]

hass --skip-pip

Note that this will disable pip install for all requirements.

[staraxis]

Having the same issue on a new install on ubuntu. The difference being that I am running python 3.6. Would this have any effect?

[cgmnuk]

The very same error "TypeError: sequence item 0: expected str instance, bytes found". I'm running Arch on Raspberry Pi with Python 3.6 also.

[jamieshaw]

Also seeing this issue on a clean install of Home Assistant 0.60.1 with Python 3.5.4; both Broadlink 0.5 and 0.6, with latest versions of pyaes and pycrypto. Have updated both switch and sensor broadlink.py files to use 0.6 to no avail.

(This was previously working on a previous install, but have reconfigured using pyenv-virtualenv).

[martyouel]

Just received my RMPRO today and I try to make it work with HA.

I'm now at the same point here --> TypeError: sequence item 0: expected str instance, bytes found

I'm running on Windows.
I got problem with PyCrypto on python 3.6
So I just rolledback my system to python 3.5.4 and now i'm at the same point with the error above

[benh57]

Looks like this is related to conflicting pycrypto vs pycryptodome installs. hass broadlink plugin fails to import AES, so falls back to 'pyaes', which does not work.

I was able to resolve it with the steps noted here:

#2411

pip3 uninstall pycrypto
pip3 uninstall pycryptodome
pip3 install pycryptodome

[jamieshaw]

Confirmed. Installing pyrcryptodome resolves the issue.

Purged my venv and started afresh. Installed pycryptodome before running hass for the first time and no more errors in the log.

[martyouel]

First, thanks for your answer guys.
Second, i've got no luck. I tried what you wrote but I still have the same problem :(
When I did the uninstall of pycryptodome I got the message that it was not installed.

TypeError: sequence item 0: expected str instance, bytes found

Any idea ?

[benh57]

You need to do the uninstall/ reinstalling within the virtualenv used by hass.

[martyouel]

umm sorry for the newb question but i'm not sure to understand what you mean by "within the virtualenv used by hass".
I'm running on a Windows 2k12 server.

Right now the only way I was able to incorporate my RM PRO within my home automation is by installing another automation system on another computer (Domoticz). So I use HA as my main automation system and call all my RM PRO switches by using the Domoticz API.

Have the same issue on fresh install

[jamieshaw]

@AMSHL Have you tried the steps above to install pycryptodome before Hass self-installs the pycrypto libraries?

[AMSHL]

@jamieshaw Yes, tried that already - no result.

[juan11perez]

@benh57 thank you very much for the instruction. I implemented and got my Broadlinks working!!
this is the commands

sudo systemctl stop home-assistant@homeassistant.service
sudo su -s /bin/bash homeassistant
source /srv/homeassistant/bin/activate
pip3 uninstall pycrypto
pip3 uninstall pycryptodome
pip3 install pycryptodomepip3 install
exit
sudo systemctl restart home-assistant@homeassistant.service

[oldfart101]

pip3 install pycryptodomepip3 install

[grea09]

I openned another issue since the logs wasn't the same but there's an easy fix by simply updating the broadlink library.

[balloobbot]

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.

Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍

[balloobbot]

This issue will be auto-closed because there hasn't been any activity for a few months. Feel free to open a new one if you still experience this problem 👍
