How's it going jimler75, do you have consumption statistics to show? (Just curious if it works or not)

Hi ... it’s working great!

Don’t know if the data is correct though? But my best guess is it’s okay :-)

I’m happy - but I’m still learning! Can’t see where to setup alarms (if there is one - then send mail)

Nice!

There is a plugin for custom alarms, creatively called 'customalarms'... Enable it in /etc/pellmon/conf.d/enabled_plugins.conf and set it up in /etc/pellmon/conf.d/plugins/customalarms.conf. Then you can set up monitoring of any amount of 'items' with limits and comparison conditions.

Email is set up in conf.d/email.conf, it will then send a mail whenever an alarm is trigged by the plugin. I use it with a gmail account, but note that due to google being google there is a roadblock: https://github.com/motoz/PellMon/wiki/Gmail-and-PellMon

Note that this is not automatically connected to any 'alarm' condition of the burner, which is of course what we really want. There is probably some kind of alarm state available in the status.xml that could be connected to pellmon by adding it to the mgm.conf file, but I didn't get that far as long as I had access to the burner controller. Maybe you could have a look at the status.xml file and see what changes there when you for instance run out of pellet? Or does anybody already have that info?

Hi guys
Tried installing pellmon on my raspberry pi but cant get it to work. Debug logs shows 401 auth error. Connecting to an MGM Junior with an TCnet controller version 1. I cant seem to find any login info(admin / boiler) in the MGM plugin code. Anybody got it to work with controller version 1 ?

There is indeed no provision made for explicitely setting username and password for http basic authentication, since the TCNET II controller doesn't have it (for some reason). Maybe the reason is that when the connection is not encrypted the username and password is transmitted in plain text so it's not worth much anyway. But since the TCNET I controller apparently uses it, you can simply add it to the IP setting which is just a text string used to form the url.

Enter the IP like this:

Kode: Vælg alt

username:password@1.2.3.4

should work...

I could add settings for username and password later, that would make it simpler to use it with TCNET-I (providing it actually works of course). The configuration file might need adjustment for TCNET-I, and could probably be extended for TCNET-II also as I didn't map out everything from the status.xml in the default configuration. If someones want to dig into the details and map out everything useful...

Thanks for trying out the code!

Thanks, It works with the user:pass@ip

And thank you for you good work with the plugin - I have looked for years for something like this.

The tcnet controller 1 interface:

Status.xml:

<response>
<err0>0</err0>
<err1>0</err1>
<err2>0</err2>
<err3>0</err3>
<err4>0</err4>
<led0>1</led0>
<led1>0</led1>
<led2>0</led2>
<led3>0</led3>
<led4>0</led4>
<led5>1</led5>
<led6>0</led6>
<led7>0</led7>
<btemp>60</btemp>
<utemp>60</utemp>
<otemp>24</otemp>
<ftemp>64</ftemp>

Greatl!
Looks like it's using different xml tags for everything. You can edit your mgm.conf to match the status xml for what you have, for instance boiler temp was:

Kode: Vælg alt

i1_item = boiler_temp
i1_label = Boiler temp
i1_data = T1
i1_longname= Boiler temperature
i1_description = Boiler temperature
i1_unit = °C
i1_tags = All Basic MGM Temperatures

, change it to:

Kode: Vælg alt

i1_item = boiler_temp
i1_label = Boiler temp
i1_data = btemp
i1_longname= Boiler temperature
i1_description = Boiler temperature
i1_unit = °C
i1_tags = All Basic MGM Temperatures

and so on. Just delete (or comment away) the things you don't have (like oxygen and fan rpm). But to get pellet consumption calculation to work there will have to be some code updates. The plugin code 'hardcodes' the xml tags for power and 'process state' used in the calculation here: https://github.com/motoz/PellMon/blob/2 ... __.py#L202 , these are not found in the tcnet-I so it doesn't work.

ok I will try that - thanks:)

Hi
I’ve been offline for summer project, as I only use my MGM in the winter season.
I have a guide to get started (as I did several re-installs of the Raspberry Pi)
I will post it very soon.
Huge thanks to Motoz for doing and continuing this project.

motoz · Indlæg af **motoz** » 18 okt 2019 09:22

Hello again Woop! Maybe you noticed that we have a release version now, did you try it out yet? (No changes from what you have, but easy to install)
