Support for New Widetech Dehumidifier (nwt.derh.312en) #1

gerliczky · 2020-12-25T08:09:38Z

Dear @al-one ,
I have successfully added hass-xiaomi-miot addon in HACS as custom repository. I managed to add my New Widetech Dehumidifier (nwt.derh.312en) device on the integration page in Home Assistant.
My problem is that I do not see my device neither devices nor in entities.
I assume this device is not yet supported by the addon. Can I help you somehow to support this device?

al-one · 2020-12-25T08:40:22Z

@gerliczky Can you find the miot-spec type for me.

This is one of the ways to get it:

Use MiHome mod by @vevsvevs (only Android)
1. Down apk from СКАЧАТЬ ВЕРСИЮ 5.x.x
2. Create folder /your_interlal_storage/vevs/logs/
3. Find spec_type from vevs/logs/devices/your-did.json

gerliczky · 2020-12-25T19:46:40Z

@al-one I have followed your instructions.
The MiHome_5.9.19_63129_vevs.apk is installed
I logged in with my MiHome account where the Defumidifier is already added.
I can control my device, but in the txt file I found no spec_type.
There is the IP address, the device type, the token and the request response messages.

Did I miss something?

al-one · 2020-12-26T02:42:07Z

@gerliczky I'm sorry. You can get spec_type from vevs/logs/devices/your-did.json

gerliczky · 2020-12-26T05:27:33Z

Found it:

al-one · 2020-12-26T07:59:27Z

@gerliczky You can test it use add-dehumidifier branch.

gerliczky · 2020-12-26T16:13:08Z

@gerliczky What's your python-miio and home-assistant version ?

gerliczky · 2020-12-26T17:28:33Z

miiocli, version 0.5.4
hassio 2020.12.1

al-one · 2020-12-27T04:10:33Z

miiocli device --ip <ip> --token <token> info

Try this command and check your lan network.

Hardware version: esp32
Firmware version: 2.1.3

I am still using the humidifier branch. I chaged log level to debug. When I add the dehumidifier I see the followig entries on the log:

So the device added without error, but no entity was created and no new device is added.

Could you help me to fix this?

al-one · 2021-01-17T14:40:04Z

Try lasest commit of branch add-dehumidifier.

gerliczky · 2021-01-18T03:02:42Z

Unfortunately there is no change. The same message on log and neither devices nor entities are created.

I noticed that on the integration UI, when I try to add the device, only climate and sensor can be selected, so I left it empty.

al-one · 2021-01-18T04:01:43Z

Download lasest and try again.

Hi @al-one,
Do you have idea, what the problem is?

gerliczky · 2021-01-23T06:56:21Z

Does it happened, because the device is currently not supported in python-miio?

al-one · 2021-01-23T16:16:02Z

miiocli -d device --ip 192.168.lan.ip --token xxxxxx raw_command get_properties "[{'did': 'result', 'siid': 2, 'piid': 1}]"

Run this shell in HA host.
Do you have other miot devices? If you have, can they be integrated normally.

gerliczky · 2021-01-23T18:43:07Z

My dehumidifier works correctly. I can contro and get information with miiocli command.
Unfortunately I do not have another miot device.
I have executed the command you suggested. The result:

I still receive the error above when I try to add my device in HA on the Integration page.
Do you have any idea, what to do?

al-one · 2021-01-24T15:42:59Z

Sorry. I have no idea.

gerliczky · 2021-01-30T07:34:03Z

I just updated to the most recent version, and just recognised, that the device and a new sensor entity is created. :)
Are you going to implement the control entities also? (switch and services)
Could you share me an example, how to use the xiaomi_miot.send_command and xiaomi_miot.get_properties, xiaomi_miot.get_properties, and xiaomi_miot.call_action services?

al-one · 2021-01-31T11:42:51Z

You can try last commit of master.
If there is still only sensor entity, You can call new service set_miot_property to sensor entity.
