MQTT active HASS not starting

[Webserve]

Hi,

Last week i upgraded to the newest hass version 0.80.2
Now when starting hass the frontpage isnt loading anymore. In the log i cant find any error.

The solution for now is:

1. use the old bwalarm.py (arm and disarm isn't working)
2. Disable mqtt

so the problem is mqtt when i set "mqtt: false" everything working fine. (except mqtt)

in 0.80 there are some changes with mqtt and alarm_panel

Remove discovered MQTT alarm_control_panel device when discovery topic is cleared (@emontnemery - #16825) (alarm_control_panel.mqtt docs)
Remove discovered MQTT light device when discovery topic is cleared (@emontnemery - #16824) (light.mqtt docs)

Can you help me to solve this problem.

I also had issues with the frontpage recently, have you tried in incognito mode to make sure it's not just stale files in the browser cache?

[Webserve]

I had the same feeling so i deleted the cache and tried another browser. The online solution is disable mqtt

I too am having issues arming/disarming via MQTT on HASS 0.80.2. It simply doesn't arm or disarm. I've taken the latest version of bwalarm. I am trying to arm/disarm via MQTT and the Android MQTT Alarm Panel app. Have tested with a manual mqtt publish to the alarm/set topic. I see this error in HASS:

Error doing job: Exception in callback <bound method MQTT._mqtt_handle_message of <homeassistant.components.mqtt.MQTT object at 0x7ff30c2b1390>>

    raise RuntimeError('Cannot be called from within the event loop')
RuntimeError: Cannot be called from within the event loop

However, when arming/disarming the alarm via the by bwalarm front-end - i.e. the Alarm page - everything works and it does publish MQTT to the alarm topic - e.g. 'Pending', 'Armed_Home', etc.

elif new_state == STATE_ALARM_PENDING: _LOGGER.debug("[ALARM] Pending user leaving house") #self._hass.services.call("switch", "turn_on", {self._warning}) self._timeoutat = now() + datetime.timedelta(seconds=self._pending_time_by_state[self._armstate]) #self._returnto = STATE_ALARM_ARMED_AWAY

Disabled the self._hass.services.call("switch", "turn_on", {self._warning})

Everything is working now.

elif new_state == STATE_ALARM_PENDING

Thanks @Webserve! Not sure what that line of code was for, but commenting it out seems to have worked for me. I just tested it and I didn't notice anything broken. Alarm warning still works when triggered from an Armed state. Arming and Disarming is working from the custom Alarm Panel, from HA, and from my MQTT alarm panel.

For those trying to do this, you can search for @Webserve's code in the bwalarm.py file (custom_components\alarm_control_panel) and comment out the line, or if your in bwalarm.py version 1.0.4 (current version at time of post) and you haven't modified anything, its line# 577:

if old_state != new_state: 
    _LOGGER.debug("[ALARM] Alarm changing from {} to {}".format(old_state, new_state))
    # Things to do on entering state
    if new_state == STATE_ALARM_WARNING:
        _LOGGER.debug("[ALARM] Turning on warning")
        self._hass.services.call("switch", "turn_on", {self._warning})
        self._timeoutat = now() +  datetime.timedelta(seconds=self._pending_time_by_state[self._armstate])
    elif new_state == STATE_ALARM_TRIGGERED:
        _LOGGER.debug("[ALARM] Turning on alarm")
        self._hass.services.call("switch", "turn_on", {self._alarm})
        self._timeoutat = now() + datetime.timedelta(seconds=self._trigger_time_by_state[self._armstate])
    elif new_state == STATE_ALARM_PENDING:
        _LOGGER.debug("[ALARM] Pending user leaving house")
577>    #self._hass.services.call("switch", "turn_on", {self._warning})  **#comment this line out - line 577**

See #52

This fixed the issues for me, including MQTT not working, and HA not starting up (which was due to getting stuck on an existing MQTT message).

thank you adipose. I've implemented your fix and it's been running well for 4 days on HA v 0.82.0
