Compatible with other stoves?

[gzeel]

Hi,

I also have a T009 Navel 2.0 wifi device on my pellet stove, only I have a JollyMec stove. Do you have any idea whether the commands that the T009 Navel 2.0 sends are the same and therefore your code can be used (with some adjustments)?

[fredericvl]

Hi @gzeel,

Actually the code mimics the API calls that are made by the iOS/Android app of Eva Calor, it does not connect directly to the WiFi module.
I downloaded the JollyMec app and have checked the API calls that are made, they should be the same but with another domain and customer code.
This would result in the following changes to get it working for your JollyMec stove:

- API_URL = "https://micronova.agua-iot.com"
+ API_URL = "https://jollymec.agua-iot.com"

- EVA_CALOR_CUSTOMER_CODE = "635987"
+ EVA_CALOR_CUSTOMER_CODE = "732584"

I'm not going to make any promises but maybe it's an idea to create a separate Python module where the the URL & customer code are adjustable so it can work with other brands too (not just Eva Calor).

[gzeel]

Wow, that would be great. In the meantime, I will see if I can get some response from my stove with your actual code.

@gzeel In the meantime, I created a more generic Agua IOT module: https://github.com/fredericvl/py-agua-iot
Just FYI if you also use Home Assistant: I also updated the HA example in there so the parameters can be set when adding the integration.

[jorgesousa1975]

can you help me a little bit more with what does it mean: "add the Micronova Agua IOT integration using the Agua IOT API url and customer code of the brand " ?

Great! That integration works with my Jolly Mec stove, however I’m getting this error :

It partially works for me, with an EvaCalor device. I can add it, get the current status, etc, but when I try to change the Operation (from Heat to Off) or the Fan mode (to set to 1 to 6) it doesn't do anything, and after a second just goes back to the same. Looks like getting the status, but not able to change. ANy ideas?

@gzeel I've released v0.0.3 with a fix for your problem, seems that some stoves are returning strings '23.0°C' rather than floats like mine '23.0'.
To get it working you will need to re-copy the Home Assistant example folder/files and restart HA (because I bumped the version to v0.0.3).
Please let me know if you have any other problems.

@jorgesousa1975 Can you also do the same and then try again?

Great, it works!

[edit]
Could you still have to change something in the set_temperature? Because I also see the same messages there if I want to adjust the temperature.

Failed to set temperature, error: could not convert string to float: '45.0°C'
(I’m setting it to 22.5, not 45.. So maybe that’s another issue..

Really thankfull, can I help you with this project or buy you a coffee?

Well actually the 45 is correct but that is behind the scenes, the temperature values are formula based (formula can differ per device) and mostly they double the value of the temperature, probably because at the WiFi module side it cannot handle floats.
But you're right and there was definitely something wrong in my logic for setting the temperature...
I was sending the value as a formatted string and actually I need to send the value as-is.
v0.0.4 has been released to hopefully fix your problem, can you bump the version in HA and test once more please?

I'm always in for a coffee 😄 ☕ https://www.buymeacoffee.com/fredericvl

Hi,
I've downloaded the Zip again, picked the evacalor folder under examples, and dumped into the custom_components. Restarted the HA, but same as before. I can get the status precisely, but I can't change from off to on, or the temperature. I see the drop down, but then I can't change it. The Fan mode is not showing any status, just "Fan mode", if I change it to 1-to-6, after 1-2 seconds it goes back to empty. Same with the operation, but that does reflect correctly the status, but if I try to change it reverts to what it was.

Works!

Tested so far:

on/off stove -> OK
change temperature -> OK

[jorgesousa1975]

Unfortunately not for me, I've tried the specific one EVACALOR as well as this more generic of AGUAIOT.

Maybe I was a bit unclear but the changes I did were only on the generic AGUA IOT one.
Since the codebase is pretty much the same I suggest to use the AGUA IOT integration, then I don't have to maintain 2 projects.

Since the actions you've tried did not succeed, this should be logged as errors.
Can you copy-paste the errors / logs of Home Assistant?
Without logs it's quite impossible to troubleshoot your issue...

[jorgesousa1975]

How do I get the logs? Since there is not really errors, is there a place where I can get the logs from, specifically to this component?

@jorgesousa1975 : What parameters did you use to setup the integration? (URL, customer code, brand id)
It looks like the URL is not available but you would not be able to setup the integration if that's the case, so I'm a bit wondered in fact...
