MqttIo crashed! due to output configuration

[piotruscilko]

After update to 0.2.0, add-on MQTT IO in HA, is not starting due to output configuration issue - when i delete part of the code for outputs (as below: Config of outputs), the rest is working well (mqtt io starting properly, with only sensor configuration).

Hi, this ist a Problem with HASS IO, because you can't get access on /dev/mem. See #293

Sorry

[piotruscilko]

OK, thanks for clue.

[BenjiU]

No problem. What sensors are working for you? i2c?

DS18B20 connected directly to raspberry pi (default pin). At the moment it is simple configuration: 1 sensor + 1 output (relay), just prepared to further development.
