msh300hk object has no attribute 'get_subdevice

[sirhaplo]

I've bought a Meross MTS150 Kit, with a thermostat ( MTS150 ) and a hub ( MSH300HK ).
The integration see my hub, but no devices, and there isn't a hub device.

Here a piece of log that continue spawning on my logs :

There is something i can do ?
Are these devices supported ?

Thank you a lot for your work, it's really appreciated

Hi @sirhaplo ,

after a bit of digging, I realized that your HUB version (MSH300HK) is the new "home-kit" hub version, which has not yet been tested with this integration and with its low-level python library. Unfortunately I do not own any homekit version of this HUB to test and develop support for.

I'll mark this thread as "feature required" for the moment. Hopefully we'll add support for this device in the near future.

In the meantime, you might be able to simply add this device via the home-kit support in HA.

[sirhaplo]

Hi Alberto, i would like to help on this issue. Can you adress me on the fast way to make some test ? I have experience on python Dev and i could try to build up a pull request for the projects

[sirhaplo]

Hi Alberto, i found in the merros-iot library documentation the section about sniffing data and i've done a brief scan of some commands from the device.
I attache here the data.zip results.

data.zip

I hope it will help.

Grazie
Daniele

Ah I suspect this answers my issue also - I have the homekit hub.

Homekit integration did work and showed my MTS150 valves but I have a mix of MTS100/150 and the 100s didn't show.

Interestingly the Meross LAN add on worked using meross cloud integration - it found the hub and all mts150/100 valves!

I would like to see this integrated so will keep track so I can move to 1 integration in the future.

[albertogeniola]

Hi!
can you please provide a capture with the new version of meross_sniffer and provide the collected logs here?

[KiraPC]

Hello @albertogeniola. I've also the new valve version with HK support and them are not displayed on HA.

Anyway, Homebridge support them, maybe you could look at this repo https://github.com/bwp91/homebridge-meross for reverse eng, maybe they use the same protocol.

Otherwise, let me know if I can help on integrate them.

EDIT: I found this error in HA logs Could not find any specific subdevice class for type mts150. Applying generic SubDevice class.

NB: I had to disable the plugin because my meross app was not working properly since I started your plugin, maybe for too much requests.

[sirhaplo]

Hello @albertogeniola i did a new capture with new sniffer and new API.
I attache che zip file here :
data.zip

I did some activation, deactivation and temperature settings.

I hope this will help with your software.
Thanks so much

Hi all.

First of all, @albertogeniola , thanks a lot for your hard work, it is very appreciated here.

I have bumped with the same error:

AttributeError: 'msh300hk:4.0.0:5.5.32' object has no attribute 'get_subdevice'

Is there any way I could help to fix this?

[albertogeniola]

Hi @sirhaplo and @ga11ego,

I've released a new beta version, v1.3.2beta1. I believe this version addresses - among all - also the issue you reported.
Do you mind testing the new beta and provide feedbacks?

Thanks!

[ga11ego]

Hi @albertogeniola ,

Thanks for your efforts. I will test it and report back to you as soon as possible.

Hi @albertogeniola ,

Sorry if I ask something too easy, but I'm a bit confused. I was not ussing homeassistant, but only meross-iot.

The piece of code is this:

http_api_client = await MerossHttpClient.async_from_user_password(api_base_url='https://iotx-eu.meross.com',
                                                                  email=EMAIL, 
                                                                  password=PASSWORD)
manager = MerossManager(http_client=http_api_client)
await manager.async_init()

# Retrieve all the MS100 devices that are registered on this account
await manager.async_device_discovery()
sensors = manager.find_devices(device_type="msh300hk")

if len(sensors) < 1:
    print("No msh300hk plugs found...")
else:
    dev = sensors[0]
    await dev.async_update()
    temp = dev.last_sampled_temperature
    humid = dev.last_sampled_humidity
    time = dev.last_sampled_time
    print(f"Current sampled data on {time.isoformat()}; Temperature={temp}°C, Humidity={humid}%")
manager.close()
await http_api_client.async_logout()

So i don't know how to install or manage the meross-homeassistant (i am on a RaspBerry Pi) I have read the readme.md doc but can't figure out what to do.

[albertogeniola]

Hi @ga11ego ,
this repository is about the HomeAssistant component. You should have opened the ticket on the MerossIot repository instead. In any case, I believe you just need to upgrade the MerossIot library to v0.4.7.2b3:

pip install meross_iot==0.4.7.2b3

Then you should be able to see the subdevices attached to the MSH300HK hub.

Hi @albertogeniola ,

Thanks a lot for your patience. Now I realise I posted the error in the wrong repository. Sorry for that.

Best regards,
Christian
