S40 firmware 4.27.0054 - Exception in _processEquipments
Describe the bug With the newest version of the S40 software, it appears that the format of some of the JSON has changed from a single "value" to an array of values (example of the new JSON below). This causes an exception.
This causes the enumeration of equipment to fail and many entities to be Unavailable.
To Reproduce Upgrade thermostat to the latest Lennox version (4.27.0054)
Expected behavior The code should accept both legacy and new "values" JSON data formats.

The section it is having problems with is the equipment parameters. The excerpt supplied is from the equipment features. So we will need the entire message.
Please configure message logging, see this documentation:

Restart HA, let it run for 5 minutes, then post or email me the log file.
Thanks for the file.
None of the equipment parameters for eqtype=18 (air conditioner) have any values and have a descriptor of "error". The other equipment seems fine, so it's just that one unit.
While I can and will update the software to not crash when this occurs. The equipment name and the parameters for the air conditioner are not available. The diagnostics look ok.
I would try power cycling everything. The S40 panels, indoor units, outdoor unit. And have the integration not running. To see if that corrects the problem. If it doesn't go into the panel and go into advanced mode / equipment and look at the air conditioner parameters. This display and the json data should be the same.
Here is the excerpt from your message.

The exception has been fixed in the API. When it encounters this issue, it will default the name to the equipment_type name which is this case is "Air Conditioner". The equipment parameters will get created, there values will be None.
To test with the updated API, edit the custom_components/lennoxs30/manifest.json and change this line from
"requirements": ["lennoxs30api==0.2.14"],
to
"requirements": ["lennoxs30api==0.2.15"],
Restart HA and it will pull the new API down automatically.

The exception is resolved with the API change, thank you. I have rebooted the indoor, outdoor and thermostat units but I'm still not getting good data.
I have time this weekend and will try a full power down again (have to climb into the attic so it's a bit of a pain)
Thanks for the update. You may be able to toss the breakers. Mine has a 30amp for outdoor unit and a 20 for the air handler.
