Control MCZ Maestro pellet stove via HACore trough MQTT

smo_at · April 16, 2023, 4:14pm

@Robbe-B First of all - thanks for your work!

Can you tell me, what I’m doing wrong, when I get the error "Try setup again: ‘index-vel_v2’?

I’ve a MCZ EGO Hydromatic 12 M2 which is connected successfully to the cloud (APP works fine)

Here’s a part of the debug log:

Thanks in advance for your help!

PS.: Is there a way to support you and Crisicus?

Hello there, would you be able to make an issue on Github with a diagnostic attached?
You can find the Diagnostic on the device page. I can’t quite tell if you can access that on your screenshot, or if the integration fails to setup entirely.

If you can’t, can you provide the stove model info as shown in the system info page in the app? I’ll make a model specific config for you that doesn’t have the index_vel_v2 so we can move from there.

Hello there!

Unfortunately no diagnostic option, as you assumed.
Issue added on github - thanks in advance!
All the best

o0larry0o · April 26, 2023, 4:44pm

Hello everyone.

Are there still people using this integration from @Seb_Lz

It stopped working this afternoon for me.
I added an issue on github, and so I double it here

Here are the logs, that is looping like this.

Does anyone have the same problem ?

Thx a lot

qgene054 · April 26, 2023, 9:12pm

I’ve got exactly the same problem

o0larry0o · April 26, 2023, 10:55pm

I’m trying to switch from cloud to local connection.

I managed to activate the wifi card of my RPI4 and keep it connected to the stove (which was my main problem 6 month ago …yay)

But there is nothing on the MCZ integration.
nothing in the log, nothing in MQTT Broker …

@Seb_Lz if you are still around we could use a hand

thx a lot

EDIT : got It … the MQTT topic are different

Seb_Lz · April 27, 2023, 8:45pm

Hello @o0larry0o , should be fixed in the new version

Seb_Lz · April 27, 2023, 8:46pm

Hello @qgene054 : try out the new version, it should be fixed now

qgene054 · April 28, 2023, 6:56am

Yes, it works again. Thank you @Seb_Lz for the update

o0larry0o · April 28, 2023, 7:17am

Great !!
thx for still being around

Although it allowed me to switch to local connection instead of cloud

About that, I tried to make a fork of your add on to add the possibility to reduce the refresh interval on the local version, but I have no idea how to publish a package …-_-
I’m really not a dev, do you think you could implement it ?

thx a lot

Seb_Lz · April 28, 2023, 10:15am

Do you mean you want to increase “get_stove_info_interval” : ha-addons/maestro.py at 77abf1f34901931f7985ff2a1b0e76d1966ced88 · SebLz/ha-addons · GitHub ?
If so, I suppose it should not be too hard to do. I’ll have a look at it when I have some free time (possibly this weekend).

o0larry0o · April 28, 2023, 3:24pm

Yes exactly,
I was thinking of a variable in the configuration page/YAML

and actually i was more to decrease it
15 sec is waaaay to long for me.

I think it’s 20 minutes tops ^^

It would be cool, thx a lot

Seb_Lz · April 28, 2023, 9:35pm

I’ve published an update with this new parameter, however I haven’t tested it… Since it was quite a small change I took the risk to just modify the code on the fly but would still be good to confirm that it doesn’t break anything else ^^

o0larry0o · May 1, 2023, 9:17am

Niiice.

I’m testing it right now, i’ll keep you posted !
thx a lot

Voidfloop · September 30, 2023, 9:05am

Hello guys,
I only see the sensors and diagnostics on my two pellet stoves. Unfortunately there are no controls.

Greetings from Germany

Robbe-B · October 5, 2023, 1:50pm

@Voidfloop,
This should be fixed in the v0.4.0-beta
Where I’ve added Basic support for the M1+ models.
You should see this now:

Cheers !

Kykkus · October 8, 2023, 8:22pm

@Seb_Lz i have tried to setup you addon (i have the old app of mcz). But when i try to add the integration hacore reboot.

Seb_Lz · October 8, 2023, 8:51pm

Hi, I’m not using any integration, just my addon, not sure what you are referring to

Kykkus · October 9, 2023, 4:13am

thanks for the answer: but shouldn’t we
install the addon
then go to integrations page
add the stove from there?

if I do “+ integration” and select your mcz maestro addon it gives me the Host of the stove, the port and the seconds between the updates. Then I press send and ha core restarts. I have to do this, right? or do I have to create the stove by hand in the yalm? Thank you

o0larry0o · October 16, 2023, 6:24am

Hello ^^
I’m back here

@Kykkus I looks like your using the add-on from @Seb_Lz AND another integration.

The add-on from Seb, does you need you to go to the integration page, after installing the add-on you need to configure it in the Add-on page to connect your stove
