I’m dipping my toes in the development side of Home Assistant, and want to start by making some tweaks and additions to the modem_callerid component.
So I found the source and copied it into config/custom_components/sensor. I then made two small changes. I created a new function called hangup, and I registered a new service called hangup_phone:
...snip ...
modem.registercallback(self._incomingcallcallback)
hass.services.register("modem_callerid", "hangup_phone", self.hangup)
hass.bus.listen_once(EVENT_HOMEASSISTANT_STOP, self._stop_modem)
def hangup(self, state):
"""Hangs up the call"""
self.modem.write("AT+CHUP")
def set_state(self, state):
"""Set the state."""
self._state = state
...snip...
I then reload Home Assistant (either via the config page, or by SSH’ing in and running hassio host reboot But after that, my HA page just sits there on “Loading Data”, and it never shows me the overview. Looking at the logs, I get this:

…do I need to do something else to override a custom component? Is this not the way to go about it?
