Component/platform: RFlink/HASS running on Imac with macOS Sierra

Description of problem:

Getting errors on some sensors, and the auto add function does not work.

Expected:

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

rflink:

Maybe it is due to the baudrate or other serial settings being slightly off causing invalid data. Could you try using the python-rflink library directly to see if the same error occurs?

For the problem of devices not being added. From the logging I can see new devices are recognized. Maybe the error causes them to not be added as the task is broken? Otherwise could you reduce the config to the minimum required to run Rflink, test it and post the complete config and results?

I found a small bug because of this (https://github.com/home-assistant/home-assistant/pull/7492). The change might not solve your problem at the core but at least it should prevent the code which caused the exception to be called.

If you copy this (https://raw.githubusercontent.com/aequitas/home-assistant/56c0a45a658ac441ee56224515dad10518148575/homeassistant/components/rflink.py) file into your custom_components you should be able to test it.

@aequitas I also noticed a lot of UnicodeEncodeError recently. I can confirm that the new rflink.py file works. No errors anymore.

Will the fix be part of the next HASS release?

[aequitas]

It has been accepted into the dev branch so I expect it will be in the next release.
