[Scishare Coffe Maker] params commands not working

[khmelevskikh]

Hi,
As discussed in a previous thread raising a separate report. I've tried to use Scishare Coffe Maker, but for me script doesn't work with parametrised commands like boil_water/brew_americano
Device:

Model: scishare.coffee.s1102
Hardware version: ESP8266
Firmware version: 1.2.8

Version:
miiocli, version 0.5.5

Testcase:

/usr/local/bin/miiocli -d scisharecoffee --ip <ip> --token <token> boil_water 300 90

I used the names given in #833 (comment) for the implementation.

Could you manually try to change it to Hot_Water just in case it was fixed in some never firmware versions (although @matteos1 explicitly stated that the name misses r? Or test changing the parameters, just in case your selected parameters are out of range for what is accepted by the device?

[khmelevskikh]

This one works fine:

miiocli scisharecoffee --ip <ip> --token <token> raw_command Hot_Wate
Running command raw_command
['ok']

so I don't believe it relates to missing 'r'
Other parametrised commands aren't working as well:

miiocli scisharecoffee --ip <ip> --token <token> brew_espresso 30 90
Brewing 30 ml espresso (90C)
False

In Mi Home I can set 30 ml 90C for espresso. I've also tried with different values

[khmelevskikh]

Played with python script a bit:
This works fine:
return self.send("Hot_Wate")[0] == "ok"
This works fine as well and gives me correct ml value:
return self.send("Hot_Wate",[amount])[0] == "ok"
This one gives me 300ml(constantly) and temp is changing now:
return self.send("Hot_Wate",amount,temperature)[0] == "ok"

Would you mind creating a PR for the necessary changes?

[matteos1]

some solution?

[khmelevskikh]

I'd love too.. But I didn't find the exact solution... I still have no idea how I can control both amount & temperature at the same time...
If anyone have any suggestions I can test...

[matteos1]

how could i help?

[khmelevskikh]

I've checked that for my machine it cannot pass more than one parameter for any command, even for raw_command Americano_Coffee [80]
So I've no ideas... Can we make params optional? So at least we will be able pre-set params in mi home and use it from script without options

Anybody tried wiresharking stock app? Can't try myself just yet - I'm only thinking of getting this very coffee machine quite soon.

I just added some information about how to perform traffic analysis to figure out the protocol to the docs (#1471 - https://python-miio.readthedocs.io/en/latest/contributing.html#improving-device-support). If someone with a device wants to do that and create a PR, I'm happy to help if needed.
