Python plugin: Xiaomi Mi Robot Vacuum Topic is solved

[mrinner]

Error: CConnection_connect:, illegal operation, Plugin has not started yet.

Try the updated version 0.1.1 of plugin.
Also test.py updated for better error handling.

Thanks!

Next update (I got some time off from work so I can play around with Domoticz ): Building goes fine, running test.py goes fine (the 47 seconds in clean_seconds is correct. I don't have a very small house but I test started the mi robot yesterday to see it was online )

test: python modules path: ./.env/lib/python3.4/site-packages

However when i wanted to open Domoticz I got an offline message. Running systemctl status it showed 'exited'. Restarting the service didn't help so I renamed the xiaomi-robot folder and tried again. That didn't work. I than rebooted my rpi and that got Domoticz up and running again however without the Domoticz webserver. Strangely enough the xioami-robot server was running. Only after removing the complete xiaomi-robot directory and rebooting the Domotics webserver started again.

Unfortunately I don't know where Domoticz keeps its error logs so I can't give you that information (without the webserver I can't acces the logs from my browser) but it seems your server and the domoticz server can't get along.

Thanks for the debug! Now plugin looks much better than yesterday (tests works).
Let me know domoticz version. Today I've tried to help one person which uses stable 3.8153 and domoticz hangs, but after update to the latest beta plugin works fine (I'm on 3.8658)

You can configure log to file: edit domoticz.sh:
uncomment line, and change path: #DAEMON_ARGS="$DAEMON_ARGS -log /tmp/domoticz.txt"

Hi Mrinner,

Many thanks for your plugin and clear wiki!

I’ve installed all the prereqs, got the token and added the vacuum cleaner to Domoticz. But for now it seems that i cannot communicate with the vacuum cleaner. I hope you our someone can point me in the right direction with this issue...

Firstly i got the Domoticz offline message like Ilheim (post above). So updated Domoticz to the latest Beta version. This fixed the Domoticz Offline message.

But i still cannot communicatie with the vacuum.. what i did so far:

- checked all the prereqs again
- checked the token
- checked the vacuum’s IP (from Android App & i can ping the device)
- rebooted the Raspberry PI

[mrinner]

But i still cannot communicatie with the vacuum.. what i did so far:

1. Firstly disable the plugin hardware.
2. Then check python process by "ps aux|grep server.py" or via "htop" and kill it if process is running.
3. Run test.py
4. If test.py works properly - you have 2 ways:

a) enable plugin with right settings and debug mode and check logs (local server should start with plugin automatically)

b) run local server manually by "python3 server.py IP TOKEN" (as service, or in "tmux", or as background process if you want) and then just enable plugin. Plugin will start connecting to this server and you will see it in output.

Thanks for the reply!

I've killed the process and have (seem succesfull?) a reply from test.py:

I've killed the process and have (seem succesfull?) a reply from test.py:

Test is OK.
Seems plugin system cannot run subprocess (local server) correctly. I will recommend you choose plan B for now:
run server manually and then start plugin
"python3 server.py IP TOKEN"

Hi,
Thanks for this plugin !!!

Same problem than Tommie, same solution (plan B!)

[Dnpwwo]

The plugin framework is single threaded so sub-processes won't work properly, this is documented on the wiki http://www.domoticz.com/wiki/Developing_a_Python_plugin:

The following things should not be attempted using the Python Framework:

• Use of asynchronous code or libraries. This will not work the way you expect.
• Use of call back functions. This will not work the way you expect.
• Waiting or sleeping. Plugins are single threaded so the whole plugin system will wait.

[mrinner]

The plugin framework is single threaded so sub-processes won't work properly, this is documented on the wiki...

I thought "subprocess.Popen" should work correctly (start external python script in background).. but seems on some platforms issues with it.

[Jacco7702]

So for solution B how have you solved it when a restart is happening (for any reason....).?
Tried to solve it with shell script via cron but I did not fix it yet at least ...

@mrinner Thanks for all your work. Really cool to see it work in Domoticz Is there an update in the near future perhaps? And also a note on the github repository would be nice

[markcame]

@mrinner thanks for the developing of the plugin, i've decided to upgrade to the last version today but i ran in some problems.

First as already described i have to manually run the server.py because the domoticz cannot run as subprocess.

as second it seems that now i can send command but nont recive status from the robot, the server recive all correctly but passing to plugin somethings goes wrong attached the log of domoticz.

Hi, I have this error attached, I installed all necessary and vaccum works fine, but always I recived this message every minute, my domoticz is installed in a Rasberry Pi 3,

Thanks you!

[juanfranrg]

Solved, I changed domoticz stable to beta and works perfect without errors, thanks you for the plugin! Great work!

Plugin updated to 0.1.2
- Now MIIO Server runs outside plugin, so you need some preparation for that change.
due issues with dz <=> python integration limits, in future releases I will add option to start server with plugin or outside because this works on some environments
- Added miio_server.sh for run miio server as service
- IP and TOKEN moved from Hardwave->Settings into miio_server.sh

Check the https://github.com/mrin/domoticz-mirobot-plugin


Plugin works on latest beta of domoticz, because python framework api has some changes which not supported by stable release 8.153
