ValueError: invalid literal for int() with base 10: 'NONE'

[GitPetri]

I have a Home Assistant dyson integration and the following error message appears in the log: `File "/usr/local/lib/python3.10/site-packages/libdyson/dyson_pure_humidify_cool.py", line 110, in formaldehyde return int(self._get_environmental_field_value("hcho"))

File "/usr/local/lib/python3.10/site-packages/libdyson/dyson_device.py", line 292, in _get_environmental_field_value return int(value)

ValueError: invalid literal for int() with base 10: 'NONE'`

@GitPetri thanks for this report! I have a few quick questions for you:

1. Is the integration failing to set up your device at all?
2. What is your device model? If you can post here exactly what the website/app says, that would be awesome.

It sounds like you have a non-Formaldehyde model, which we've recently learned has some internal naming overlaps with the Formaldehyde models that affect some of the logic in libdyson.

My next priority on this project is to clear up the Formaldehyde conflicts so both types can live happily together. Your answers could really help!

Hi there

1. the integration works, it seems to be just an annoying log error message
2. I have 2 Dyson devices and the models are 358E and 520 as reported by the Dyson integration device info. I assume the error message comes from the 358E which is not a formaldehyde model. The user guide for the 358E states Dyson model number ph03: www.fi.dyson.com/content/dam/dyson/maintenance/user-guides/fi_FI/airtreatment/purifier-humidifiers/ph03/369095-01.pdf Android App shows Dyson Purifier Humidify+Cool™

I get something similar, I think the machine might output a "fail" value every once in a while, and that is not-numeric. Maybe if you add and 'else' not numeric, it becomes "unknown" and not none?

v0.21.0 has been released which potentially resolves this issue. Let me know if you have issues @Anto79-ops and @GitPetri!

[Anto79-ops]

Thanks @dotvezz! Keep you posted.

[Anto79-ops]

@dotvezz just updated and no issues. Sometimes its takes a day for this error message to show up so I'll keep an eye on the logs.

By the way, I still see this in my logs , I realize that the HCHO thing is still a work in progress...but I just recently connected with a Dyson engineer on LinkedIn named David Hill. He seems like someone who would know the answer so keep you posted on that!

Entity sensor.master_bedroom_formaldehyde (<class 'custom_components.dyson_local.sensor.DysonHCHOSensor'>) is using native unit of measurement 'None' which is not a valid unit for the device class ('volatile_organic_compounds') it is using; expected one of ['µg/m³']; Please update your configuration if your entity is manually configured, otherwise report it to the custom integration author.

[dotvezz]

Yeah, the HCHO Sensor is still not using any units. This is because we haven't been able to figure out what units the sensor is reporting in, and haven't nailed down a reasonable conversation factor.

I'm super curious about whether your new connection can help us out, @Anto79-ops!

[dotvezz]

We were finally able to nail down the formaldehyde sensor! https://github.com/libdyson-wg/ha-dyson/releases/tag/v0.22.0

[Anto79-ops]

Since updating, I have not seen this message quoted here.

Thanks for fixing that!

Same for me. Thank you for fixing.

Installed v0.22.1 via HACS - Formaldehyde gives values and I got rid of the log error

[dotvezz]

I wish it didn't just have the "Eye" icon, but to fix that I'll have to add a SensorDeviceClass for Formaldehyde in HA Core. I'll add that to the list of things to do. But for now, closing this issue! Feel free to reopen or follow up if yo uhave any more issues.

[Anto79-ops]

@dotvezz you can easily change the icon using front end... Just click on the entity properties and change the MDI icon, for example:

[mundschenk-at]

I am pretty sure you can also set custom icons programmatically without a Core device class.

[dotvezz]

Aha, I'll look into setting the icons programmatically then! Thanks!
