Home Assistant release (hass --version):
0.60.0

Python release (python3 --version):
3.5.3

Component/platform:
switch/broadlink

Description of problem:
When the broadlink switch configuration is parsed the parser fails if the base64 string (generated by HA) is not padded to 4 characters:

2018-01-01 11:46:04 ERROR (MainThread) [homeassistant.components.switch] Error while setting up platform broadlink

    return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

The base64 strings are produced by the broadlink.learn_command service.

Expected:

Problem-relevant configuration.yaml entries and steps to reproduce:

irrelevant1:
  friendly_name: "HDMI switcher Sky"
  command_on:  'JgBQAAABLJMTEhMSExITEhMSExITEhMSEzcSNxM3EzcSNxM3EzcSNxMSEzcTEhM3ExISExITEhMSNxMSEzcTEhI2FDcTNxM3EgAFGQABKkkTAA0FAAAAAAAAAAA'

Add === to the end of the string and it is fine.

Additional info:

This has been fixed for the send_packet service by #7669
