Error: error:0607F08A:digital envelope routines:EVP_EncryptFinal_ex:data not multiple of block length

[Jamelnacef]

Hi,

I receive this error after I've setup one flow of Plejd.

I run node-red v1.0.0 on my MacBook Pro Mojave v10.14.4 and node-red-contrib-plejd v.0.0.7

Below is my node-red log and my flow ....

What am I missing? I also receive similar error while sending to Plejd out.

I can´t even install it on my mac. I´ve only been running it on my raspberry pi.
But after some googling it may have something to do with the crypto code.

Could you please try to edit the file /Users/jamelnacef/.node-red/node_modules/node-red-contrib-plejd/plejd.js (based on your log above..) and remove line 323: cipher.setAutoPadding(false) and then restart node-red? If it works I'll create a new release without it.

[Jamelnacef]

Thanks for your reply!

That did indeed work for the error.

But however, I receive very high values on the dim value on the Plejd in payload, please see below:

1st I switch on one controller from push button:
{"id":139,"state":"On","dim":65535}

Then I switch it off from same push button:
{"id":138,"state":"On","dim":65535}

It's probably the inputAddress of the buttons I believe, since this device has ID 16 in my. sites file.

On the other side, when I try to control the same device with played out nothing happens, I tried to send these two on msg.payload:

{id: 16, state: 'on', dim: 255}
{id: 16, state: 'off', dim: 100}

However nothing happens and there is no output in the node-red console log.

Thank you!

I believe this can be related to the bluetooth driver of Mac OSx, I will test my setup on a RPI 3 instead.

But thanks for the help :D

[emilohman]

Strange.. please let me know how it works out for you on your raspberry.

[Jamelnacef]

It works well on my Raspberry. Though, I can't use the Plejd app while running Plejd node, you have same issue ?

[emilohman]

yes unfortunately, it's because Plejd can only be connect to one device at the time. It's the same for the home assistant plugin that I have ported.
