TypeError: Cannot read properties of undefined (reading 'C')

[Pichiasister]

Hi I'm experiencing error msg on 2.5.0-alpha.2 which prevented Homebridge start normally:

TypeError: Cannot read properties of undefined (reading 'C')
    at AirConditioner.addHeaterCoolerService (/volume1/homebridge/node_modules/homebridge-sensibo-ac/homekit/AirConditioner.js:221:52)
    at new AirConditioner (/volume1/homebridge/node_modules/homebridge-sensibo-ac/homekit/AirConditioner.js:90:9)

    at HomebridgeAPI.<anonymous> (/volume1/homebridge/node_modules/homebridge-sensibo-ac/index.js:127:9)

Is there anyone can shed me some light on how to workaround with this?

FYI Using Synology DSM w/ node.js v20.13.0 running on Homebridge v1.8.1, and tried run on docker which didn't seems able to clear the issue.

Hi @Pichiasister

Thanks for raising, I'll take a look. I suspect your unit may not be returning temperatures in C (celsius) for one of the modes.

To assist with the investigation it would be great if you can provide your Sensibo API response, this will show what capabilities etc your unit has.

To gather this, please turn the debug log on, by adding "debug": true in your settings within Homebridge. See here for more details. And then share the large JSON payload that is returned to the Homebridge logs, it should appear just after a log line like the following:

Thanks @Pichiasister

As I thought, your Auto mode is returning no temperatures. I’ll look to add a fix and release a new alpha to prevent the crash.

Follow-up question, on the devices remote (not Sensibo), when you are in Auto mode, can you set a desired temperature? Heat, Cool, Dry and Fan all have them (in Sensibo), but not Auto.

If you can set a temperature in Auto on your remote, then you need to set an alternate remote code in Sensibo (Sensibo Support can assist). That should also prevent the crash.

Hi @benwebbbenwebb sorry that I've checked and it seems no temperatures can be set in the AUTO mode. Btw I've exclude AUTO mode and has avoided crashes.

[benwebbbenwebb]

Hi @Pichiasister

Yes, I believe that should work, great idea!

modesToExclude is the setting name.

Add "modesToExclude": ["AUTO"] to the settings JSON config.

Hi @Pichiasister

I've released v2.5.0-alpha.3 to fix the issue you've mentioned here, when you have some time would you mind updating and re-enabling AUTO mode to confirm that the issue is resolved?

[Pichiasister]

Hi thanks @benwebbbenwebb, I've updated to v2.5.0-alpha.3 with AUTO mode on, and this has been fixed.
