BroadLink Switch Component

Configuration
1

Hi,

I have been attempting to get HA to switch a TC2 on/off from following some information I have found here:

As you can see from the bottom of the issue someone has used the tasker app to get hold of the codes but the format is like this:

e9144600df090916160916090916091616090916160916090916160916090916160909161609091616091609160916091609160916091609091609160916160909161609091609000148

I have used an online too to convert this to base 64:

ZTkxNDQ2MDBkZjA5MDkxNjE2MDkxNjA5MDkxNjA5MTYxNjA5MDkxNjE2MDkxNjA5MDkxNjE2MDkxNjA5MDkxNjE2MDkwOTE2MTYwOTA5MTYxNjA5MTYwOTE2MDkxNjA5MTYwOTE2MDkxNjA5MTYwOTA5MTYwOTE2MDkxNjE2MDkwOTE2MTYwOTA5MTYwOTAwMDE0OA==

But when I attempt to send the command I get the following error:

ValueError: Input strings must be a multiple of 16 in length

Anybody able to help with this issue so we can see home assistant control the TC2 switches and make the component even more useful?

Mike,

I am at your same stage - did you manage to get it working?

thanks,

Try something like:

from base64 import b64encode, b64decode
hex_data  = "e9144600df090916160916090916091616090916160916090916160916090916160909161609091616091609160916091609160916091609091609160916160909161609091609000148"
packet = hex_data.decode('hex')
b64encode(packet).decode('utf8')

Then @mikehole code becomes: 6QpCAN8JCRYWCRYJCRYWCRYJCRYWCQkWFgkWCQkWCRYWCRYJCRYJFhYJFgkWCRYJCRYJFhYJCRYWCQkWFgkWCRYJCRYWCQ==

Thanks for the suggestion but unfortunately I still get the same error:

I have also tried doubling the codes as suggested in the GitHub topics that relate to this.

There have been a lot of bug fixes in the Broadlink component since the last release.
So it might work with the next version.
So I suggest that you wait for the next release or use the dev version: https://home-assistant.io/developers/development_environment/1

@mikehole Try to duplicate the code like this:

e9144600df090916160916090916091616090916160916090916160916090916160909161609091616091609160916091609160916091609091609160916160909161609091609000148e9144600df090916160916090916091616090916160916090916160916090916160909161609091616091609160916091609160916091609091609160916160909161609091609000148

and then encode it to base64.

Let me know if ti works.

It doesn’t work unfortunately :frowning:

@mikehole Unfortunately I don’t have home assistant installed (yet…), I do plan to install it this week and i will be able to test it, If i’ll manage to get everything working i’ll let you know.

Great stuff, I see form GitHub you are a contributor to the libraries on there. Good to have you on board :slight_smile:

11

@mikehole I am just a user who tries to get things working…lol

I finally got everything working well which includes all my broadlink accessories, RM PRO, TC2, SP2 along with amazon echo.

I published a detailed document about the process here:

I just found about Home Assistant and it looks very cool, So here we go again to another journey to get broadlink integration… :slight_smile:

I went for HASS because it’s got the HueBridge out of the box so I was able to get an Orvibo S20 working with Alexa by only playing with config and no code.

And it has a good web user interface.

13

@mikehole Got it working, look at this post.

14

Great stuff. Must admit trying to follow that thread is a little confusing will wait for the next HASS release to drop to see if I can get it going. But af far as I can tell it’s the self.device.senddata(binascii.unhexlify(packet)) line that makes the difference?

Yes, this is the only change i made.

Great stuff, looking forwards to finally getting my dining room light sorted :slight_smile:
