Formaldehyd metric

[kaiherzig]

Hi, is there a way to add formaldehyd sensor? it should be hcho and hchr

I started main.py with debug and i get values. DEBUG New environmental state: {'msg': 'ENVIRONMENTAL-CURRENT-SENSOR-DATA', 'time': '2021-06-17T06:25:40.000Z', 'data': {'tact': '2950', 'hact': '0050', 'pm25': '0005', 'pm10': '0003', 'va10': '0004', 'noxl': '0002', 'p25r': '0007', 'p10r': '0007', 'hcho': '0000', 'hchr': '0000', 'sltm': 'OFF'}}

Sorry I'm not used to python

Hi there, what model device do you have?

I believe this is possible to add, but it is somewhat complicated because:

1. I don't have a device that reports this, so I'd need your help to test.
2. @shenxn 's libdyson doesn't currently support this field, so this needs to be updated first. I can likely help with this as I don't think it's super difficult.

What would be helpful to start would be a full debug log with a few samples of the hcho/hchr fields.

Apologies for the delay in responding; I've been pretty busy elsewhere lately. :-)

Thanks for that the log entry. I'm assuming you ran config_builder to generate a config? Can you provide the ProductType it discovered? (from your config.ini)

There was a change to support type 527E here: https://github.com/shenxn/libdyson/pull/9 and I'm wondering if this model differentiates itself by having the Formaldehyde sensors.

[crgreenwood]

Unfortunately not - 527E does not have the formaldehyde sensor. The one with the formaldehyde sensor is yet another model.

Ping @kaiherzig ?

Can't proceed without the information requested above -- so the other option is to close the issue.

[kaiherzig]

Sorry I’ll send you tomorrow!

Viele Grüße Kai

Sorry for the delay. producttype = 438E

[seanrees]

Thanks @kaiherzig, looks like libdyson has partial support for 438E which is why it sort of works for you.

I created a PR for libdyson to wire through the formaldehyde metrics: https://github.com/shenxn/libdyson/pull/12 which is the first step to support in this code.

[seanrees]

Update: this is ready for testing. I just released 0.3.1 which should plumb through the formaldehyde metric from libdyson.

Will you let me know if it works for you?

[kaiherzig]

Looks good :) It's working.

[seanrees]

Great news :) Thanks for filing the issue & testing the change 👍
