Add Interlogix Ultrasync Alarm System Integration #42549

caronc · 2020-10-29T00:46:09Z

Proposed change

Interlogix provides security solutions. One of which is their Self Contained (ZeroWire) Hub:

This wraps the UltraSync Hub tool I've already wrote. It additionally follows along a HA community thread identified here

Type of change

Dependency upgrade
Bugfix (non-breaking change which fixes an issue)
New integration (thank you!)
New feature (which adds functionality to an existing integration)
Breaking change (fix/feature causing existing functionality to break)
Code quality improvements to existing code or addition of tests

Example entry for `configuration.yaml`:

This component will create these sensors:

area1state: Area 1 Status
area2state: Area 2 Status
area3state: Area 3 Status
area4state: Area 4 Status

Generally, most alarm systems only set up 1 area. So area01_state will probably be the only sensor used. The others will only activate if the areas are detected to exist (and are setup on the Hub).

This integration uses the control flow setup and can be added through the HA . The sensors automatically are automatically added when this is complete:

Configuration -> Integrations -> ➕ Add -> Search for Ultrasync
Provide the IP address of your UltraSync Hub on your network, your Login and your PIN

Note: You can only be logged into the ZeroWire hub with the same user once; a subsequent login with the same user logs out the other. Since this tool/software actively polls and maintains a login session to your Hub, it can prevent you from being able to log into at the same time elsewhere (via it's website). It is strongly recommended you create a second user account on your Hub dedicated to just this service.

There are 3 services associated with this integration you can call at any time:

away: Set's your alarm system to the Away Scene/Mode
stay: Set's your alarm system to the Stay Scene/Mode
disarm: Disarms your alarm.

# Arm alarm when everyone leaves the house
  - alias: 'Away Mode'
    trigger:
      platform: state
      entity_id: all
      to: 'not_home'
    action:
      service: ultrasync.away

Is support for YAML import really required on a new integration?

I had a quick look at your PR, hopefully this review is helpful. Especially the part around entity creation and data retrieval was unclear for me, it looks you are not really utilizing the DataUpdateCoordinator. For which purpose are you sending events in HA?

Suggested change

class AuthFailureException(IOError):

class AuthFailureException(Exception):

A custom exeception class should inherit from Eception, not from IOError. On the next line you should also add pass, I believe. See https://www.programiz.com/python-programming/user-defined-exception.

Not a problem; done! 👍

+                errors["base"] = "cannot_connect"


As noted above, will this only be called when a connection is not possible or also when the credentials are not correct? (wrong pin). Currently you will always show 'Failed to connect.' (cannot_connect), which is not super helpful to the user.

AuthFailureException should be mapped to invalid_auth (Invalid authentication.). Otherwise you should rename the exception.

Can users only have one Interlogix Ultrasync Alarm System? Perhaps it is better to set a unique id and check for duplicates.

await self.async_set_unique_id(user_input.get(CONF_HOST)) # or another unique id, like a serialnumber self._abort_if_unique_id_configured()

Thank you for sharing this snippit of code. I think i did this properly; maybe you can review this part and let me know?

Are you the author of ultrasync package? It would be better to raise an error from the package and capture it here. Now all auth failures (no internet, wrong credentials, timeout) will all raise the same exception and thus the same error. This is not very helpful to the user.

I am the author, yes. I agree it's not ideal; but 3 errors you identified that are all captured into one only play a role for the users initial hookup. Then it just works flawlessly from that point on.

There is no internet requirement here; the panel is usually in the persons local home network. So presuming the user is already accessing their panel internal on their network (via web browser), they're just entering the same 3 entries here too (host, pin and password). Basic troubleshooting would be to simply try the same host information in a new browser tab.

Either way, it's still a good suggestion, but I'd have to re-factor a section of the code to handle this sort of thing. Is this required to at the start to just get support for the Ultrasync Panel into HA?

+    await hass.config_entries.async_reload(entry.entry_id)


Reloading the config entries should not be necessary, since you are using a coordinator. You could just set the new update interval directly on the coordinator.

if entry.options[CONF_UPDATE_INTERVAL]: coordinator = hass.data[DOMAIN][entry.entry_id]["coordinator"] coordinator.update_interval = timedelta(seconds=entry.options[CONF_UPDATE_INTERVAL]) await coordinator.async_refresh()

I put this code in place; i'll give it a whirl

+    # At least one sensor must be pre-created or Home Assistant will not
+    # call any updates
+    hass.data[DOMAIN][entry.entry_id][SENSORS]["area01_state"] = UltraSyncSensor(


Why is this 'dummy' sensor created? In my opinion, it would make more sense to pull all available areas first in init.py and create the sensors from there. Eventually they could all pull their latest data from the DataUpdateCoordinator.

This was required through advice provided to me by @raman325 who was a fantastic resource on the Home Assistant Discord chat at the time. Without per-creating a dummy sensor to work with nothing ever gets detected after. It's like a ticket into the event loop. If i don't create one at the initialization, future changes never get triggered.

If i do this, everything works great afterwards.

+    def device_state_attributes(self):
+        """Return the state attributes of the sensor."""
+        return self.__attributes


What are the possible attributes? You need to specify a list/dict of possible attributes, so it is clear what will be added. This cannot be dynamic.

The problem is that they truly are dynamic. The ultrasync is dynamically configured from the panel or it's internal website. I don't knjow what is enabled and disabled until i first connect to the panel (using the pin/password provided by the configuration).

Once i can connect, i can then poll for all of the zones and sensors. Different sensors have different attributes associated with them (such as a sensor like a smoke detector, motion sensors, and door sensors, etc). So I'm able to poll this and build the sensor list dynamically. It actually works really well; I've had lots of positive feedback using HACS in the time being since here.

This doesn't make sense. We have a poll interval of 1 second and a timeout of 10 seconds? The poll interval must be longer than the maximum time it takes to complete the poll.

The issue here is 9/10 the poll will return in under 1 second. So this is just more of a cautionary handling of the 1 off (so it breaks out) (let setting a SIGALRM if you will).

If it can happen 1/10 my comment above still needs to be resolved.

This is not a pattern that we want. It would be ok to add a callback in the entity and connect that via our dispatch helper to a signal.

Normally though we let the coordinator return the new data that is fetched and let the entities that subscribe to the coordinator access that data as needed.

Don't store the entity. If we need to ask the entity to do something from outside the entity we use our dispatch helper.
