Python Plugin: MillHeat

[appelflap]

Hi,

I'm building a domoticz python plugin for a MillHeat WiFi heater: https://github.com/appelflap/domoticz-millheat
And it uses this code as a connector to the heater: https://github.com/Danielhiversen/pymill

It creates 3 devices per heater found through the API: Status (on/off, read only), Temperature and Thermostat (editable)

I've tested it on my own host, with ubuntu 18.04 running Domoticz stable.
And I installed it on a Pi for a friend and it doesn't go further than the 'Started, Entering, Initialized'..
I did set Debug to enabled on both hosts.. but the Pi doesnt give a lot of info.

Anyone got an idea how to investigate further?

[edit]And one other thing: domoticz seems to hang if I want to change/remove the hardware (on my own host).. any ideas?[/edit]

This is my version:

Hi, thanks for sharing your Millheat plugin. I have installed it on my Domoticz (latest beta) with Python 3.5.4 (32 bit) on my Windows 10 based home server. After correcting paths, the plugin starts without errors but there are no devices detected. The test Mill Wifi Socket device is visible in the Mill iOS app and works fine. In the Domoticz log I can see the calling of “onHeartbeat” and “createDevices”. I have 2 other Python based plugins working fine.

There are one occasionally error in the log, “Millheat hardware (8) thread seems to have ended unexpectedly”, but this seems to be a common plugin related problem.

Do you have any tip on this?

By the way, I have the same problem as you with hang when I try to stop/alter the plugin in the hardware page of Domoticz.

[appelflap]

The plugin does a basic guess where the python packages are. This is needed for the pymill and prerequisites.
At the moment this is purely linux paths.. you can change it in the plugin.py file.

Code: Select all

# Add pip3 locations
sys.path.append('/home/'+getpass.getuser()+'/.local/lib/python3.5/site-packages')
sys.path.append('/home/'+getpass.getuser()+'/.local/lib/python3.6/site-packages')
sys.path.append('/usr/local/lib/python3.5/dist-packages')
sys.path.append('/usr/local/lib/python3.6/dist-packages')
sys.path.append('/usr/lib/python3/dist-packages')

For example (not tested):

Code: Select all

sys.path.append('C:\PythonXY\Lib\site-packages')
sys.path.append('C:\PythonXY\Lib\dist-packages')

[sema2022]

Thanks, but I think the path part should be updated (since the module starts). I find the Mill module under site-packages but there is no “dist-packages” directory in my c: disk. My extra paths are:

Code: Select all

# Add pip3 locations
sys.path.append('C:\Program Files (x86)\Python35-32\DLLs')
sys.path.append('C:\Program Files (x86)\Python35-32\lib')
sys.path.append('C:\Program Files (x86)\Python35-32')
sys.path.append('C:\Program Files (x86)\Python35-32\lib\site-packages')
# Not used: sys.path.append('C:\Program Files (x86)\Python35-32\lib\dist-packages')

I have reinstalled Python With 35.3 (as you have) and also the Millheat module and plugin, still the same problem. It seams to start as expected but no devices appear:

I'm sorry, but I can't help you at the moment. On holiday for a few weeks. Please keep me updated through the forum if you find anything. I will take a look at it when I'm back.

I'm sorry, but I can't help you at the moment. On holiday for a few weeks. Please keep me updated through the forum if you find anything. I will take a look at it when I'm back.

this can help for path trouble:

Code: Select all

# Required for import: path is OS dependent
# Python framework in Domoticz do not include OS dependent path
#
import site
import sys
import os
path=''
path=site.getsitepackages()
for i in path:    
    sys.path.append(i)
#

[sema2022]

Thanks, the path coding worked, and I could now delete the manually inserted path.append lines. However, I did not solve the initial problem with Millheat plugin not detecting any devices.

@appelflap,

And one other thing: domoticz seems to hang if I want to change/remove the hardware (on my own host).. any ideas?

The Python Plugin Framework can't hang Domoticz, what it can do is crash it which can appear the same if you are looking at the web UI and is probably what is happening here.

The 'mill' code there is a lot of asynchronous reading and writing which should be okay while the plugin is running but can cause an issue on shutdown (which happens when you 'Update' the plugin in the Hardware tab). Python has this delightful feature where there is not real mechanism to abort/kill threads (that I can find ) but it will abort the host application if there are any threads running during interpreter shutdown

What does this mean? It means that plugin developers using threads (directly or otherwise) need to make sure they are shutdown before the plugin exits. (have a look at my google plugin for an example https://github.com/dnpwwo/Domoticz-Google-Plugin)

To see if this is the case you can add something like this to your code:

Code: Select all

import threading
...
    def onStop(self):
        Domoticz.Log("Threads still active: "+str(threading.active_count())+", should be 1.")
        while (threading.active_count() > 1):
            for thread in threading.enumerate():
                if (thread.name != threading.current_thread().name):
                    Domoticz.Log("'"+thread.name+"' is still running, waiting otherwise Domoticz will crash on plugin exit.")
            time.sleep(1.0)

(although you might not want to make it wait forever)

If this is your problem you will need to work out how to stop the other running threads.

Good luck !

[appelflap]

Thanks Dnpwwo! I searched the forum for multiple days back then, but couldn't find the reason behind it.
I have changed the code on my github, but I don't have a mill heater to test with

Hi, today I looked further into my Millheat plugin problem. It seems like the devices don’t show up when they are connected to rooms in my account setup (Mill App on iPhone). After disconnecting (converting to independed devices) they appeared in Domoticz.

So far, so god, but they are only visible in a few seconds in Domoticz. In the log I see the new devices being classified as “obsolete” and deleted by the Millheater plugin as shown below:

It seems like the “createDevices” routine in the Millheater plugin detect new devices, but don’t update the “myHeaters” string and then triggers deletion.

However, the devices stay in Domoticz if I disable the “find and remove obsolete devices” code in the plugin. The values are then updated and it seems like the Api iteration towards the Millheat Cloud are working, but nothing happens when I push the On/Off buttons, something seems to be messed up .

I have tried the setup on three different PC’s with Windows 10 and Python 3.5.3 with same result. I am not a programmer or Python expert and are now stuck.

Are there any skilled persons able to give me a hint on the problem?

[sema2022]

I found out about the problem with the Millheat plugin not working in my Windows 10 based system with latest beta Domoticz and Python 3.7.2. I have 4 Milheat WiFi Socket Gen.2 devices connected to 4 ovens. The Mill devices show up but was immediately deleted again as explained in my prior post. Here is what I did to make it work in my Windows based setup:

The content of “myHeaters” is handled right after correcting the "DeviceID[0:4]” parameters in Millheat plugin lines 130, 134, 138 and 204 to “DeviceID[0:5]”. After this, the devices remained, and the heater's on/off actions works.

To have the heaters work correctly I also needed to set the “fan_status=0” in line 131 and 135 parameter to “fan_status=1”. Further I changed the heater values in line 130 from “0, str(myHeaters[heaterId].is_heating))” to “myHeaters[heaterId].power_status, str(myHeaters[heaterId].is_heating))”. This might be due to the gen2 Wifi Socket having an extra function where you can choose to utilize the internal thermostat function combined with the power On/Off switch or not, and this is controlled by the “fan_status=1” parameters, or... ?

The crash during update/closing of the Millheat plugin in the Hardware setups seems to be a less problem with Python 3.7.2, even without the lines 95 to 100 in the “onStop” routine. The threads is being closed without a crash.

Also remember to “Allow for new hardware” in the setup when enrolling new Mill devices. If not, you will get a “KeyError” in the log.

I have created a virtual hardware device setup as a selector switch with three heater modus buttons (Comfort 23c, Saving 19c and Frost 5c) running .bat scripts with Json commands controlling the 4 Millheaters. This is a very simple setup, working well (as long as device IDx are not changed).

@sema2022,
The changes you suggested did the trick. I also have a generation-2 heater. The only thing I can't get to work (or i can't find the place to do it) is to alter the setpoint for the heater)
under temperature it shows the current temp in the room. Under switches i can turn the device on/off, but i can't find a place to alter the setpoint.
Do you have any suggestions ?

[SuperZite]

Is it still some problem whit this plugin ?

I have done the changes that was explaind in this link and got the devices that was not connected to a room added but devices that was grouped to a room is not showing up.

[jobvr]

Not that I am aware of. the plugin is running fine in Domoticz. only sometimes there is a error in de LOG, bur everything is working fine

[jobvr]

Now i did run into trouble.

I had it working, but I did a complete new install on my Raspberry from scratch. Now i don't get de Device to show up.
I have a GEN2 so did the changes with the flame status ETC. However sommeting seems to be in the wrong place. I get this error in the LOG when Domoticz starts.

2020-02-22 07:56:31.999 Error: (MillHeat) failed to load 'plugin.py', Python Path used was '/home/pi/domoticz/plugins/millheat/:/usr/lib/python37.zip:/usr/lib/python3.7:/usr/lib/python3.7/lib-dynload:/usr/local/lib/python3.7/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.7/dist-packages'.

any ideas?

i have the exact same problem i think it has something to do with the paths being incorrect but i have no idea how to fix it so if you find a solution i would love to know it to!

[copywizard]

still no one that can help us whit this problem? any help in the right direction would help?

In the current version the python code tries to find the packages it needs through the sys.path.
But maybe your packages are put somewhere else. You can try including (one of) them by doing it manually.
You will have to find out which version of python you are using currently and adjust the path accordingly.

Code: Select all

sys.path.append('/home/'+getpass.getuser()+'/.local/lib/python3.5/site-packages')	
sys.path.append('/home/'+getpass.getuser()+'/.local/lib/python3.6/site-packages')	
sys.path.append('/usr/local/lib/python3.5/dist-packages')
sys.path.append('/usr/local/lib/python3.6/dist-packages')
sys.path.append('/usr/lib/python3/dist-packages')

I do not own a MillHeat device myself. So I'm not able to actively support/develop the code anymore.

thanks alot for your reply ! my domoticz uses python 3.7.2 i have tried to add this line to the plugin.py script but it keeps giving me the same error even if i try to put in the paths for python 2.7 thats also installed.

i do not ask you do develop the plugin more but it would be cool if you could help me and maybe others out by explaining how i add the right pyhton version and where i do this?

the error suggests its looking for a very long path that does not exists on my pi/domoticz install including that it is looking for a python*.zip file i have no idea why?

my python is installed in the location /usr/local/lib/python3.7 same goes for 2.7 and 2.7 has both the directories dist and site packages and 3.7 only has dist-packages in it all are empty.

thanks for any help in advanced.

Did you install the pymill component using this command?

pip3 install millheater
