Connecting via home assistant crashes on different port (1881)

[marcux01]

Not sure if my issue relates to the port? or another issue altogether, if I start haiku2mqtt like this:

haiku2mqtt -b mqtt://127.0.0.1:1881

I get:
server listening 0.0.0.0:31415

Then as soon as I try to switch the fan off via home assistant's MQTT fan component I get the error:

/usr/local/lib/node_modules/haiku2mqtt/node_modules/rxjs/Subscriber.js:246
throw err;
^

TypeError: Cannot use 'in' operator to search for 'fan' in undefined
