Please help with XIAOMI O'WS Temperature Electric Towel Rack MJ120

[Kirmas]

Device information:

• Name(s) of the device: XIAOMI O'WS Temperature Electric Towel Rack MJ120
• Link: https://www.aliexpress.com/i/1005001463369274.html - Is it ok? I have no idea how to find something more official

Use miiocli device --ip <ip address> --token <token>.

• Model: ows.towel_w.mj1x0
• Hardware version: esp8266
• Firmware version: 2.0.7

Additional context https://miot-spec.org/miot-spec-v2/instance?type=urn:miot-spec-v2:device:towel-rack:0000A09A:ows-mj1x0:1 - but all trying to send miot command returns {'code': -9999, 'message': 'user ack timeout'} error Command that works for me:

command	value	info
set_mode	"0-3"	0: 'dry', 1: 'warn', 2: 'antifreeze', 3: 'programming';
set_power	"0-1"	0: off, 1: on
set_tempdry	"80-120"	x/2 - if I send 80 my device set 40 degrees of celsius i have no idea why.
set_tempheat	"40-60"	x/2

set_tempdry and set_tempheat work only if mi home app is closed.

And now main problem all mi trying to get any property from device is failed.

miiocli device --ip <ip address> --token <token> test_properties mode power tempdry tempheat
Running command test_properties

I found integration for node js https://github.com/maxinminax/node-mihome/blob/master/lib/devices/ows.towel_w.mj1x0.js but it failing on get property too.

Maybe someone have some idea what I can to do to get this information from the device.

One more strange sing: I was trying to sniff the traffic and have a lot of data sent from :54321 to the 120.92.65.253:8053 this data is 160 or 192 length. But I cannot decode it using my token, maybe some one know how xiaomi encode data for cloud.

not miotspec device, so spec is useless here (unless you want to send cmds via cloud). use get_props (not get_prop) method, no params. it returns something like in this list

"prop.power_set", "prop.mode_set", "prop.tempdry_set", "prop.tempheat_set", "prop.temprog_set", "prop.drytime_set", "prop.percent_get", "prop.tempind_get", "prop.tempsurf_get"

device <> cloud is encoded same way, but with cloud key rather than token. in short, you can't dump it.

get_props is working. A lot of thanks.

More for future me or some one else who will add this device. ( In this time I want to finished with Yeelight lamps, and only after this start to add something else.)

I still don't know what is last zero property [9]. And how to set property number 5(In app this is dry hour for programming mode), as for me this is not very important, but would be cool know all :)

hass-xiaomi-miot support it in commit: https://github.com/al-one/hass-xiaomi-miot/commit/9cabe103929a9946ea4f2493f7d17eb5eccfb7b2

Hi everyone! I'm trying to connect to my towel rack get_props and set_power "0" work perfectly, but set_power "1" doesn't switch on my rack I can hear signal with miiocli device --ip IP --token TOKEN raw_command set_power "1", but rack is still switched off Probably it needs more parameters to start working? @al-one @Kirmas @rezmus probably could someone please say why ?

Is your mi home app was closed when you tried? When i tried it was important. Because app switch device back

Yes, I turned off internet at all Probably I have another firmware version

I don't know how to make it work =(

Okay, I managed to sniff this

<-  192.168.1.160 data= N/A

Strange that miiocli device --ip 192.168.1.160 --token token raw_command set_power 1 doesn't work for me @rezmus any ideas?

[pavlovalexey92]

Thanks all I had to send set_power [1] Space between command and parameter makes sense Thanks a lot @Kirmas
