Support for iGrill mini

[jysaloma]

Please add support for iGrill mini.

here is the SERVICE UUID:
static BLEUUID MINI_SERVICE_UUID("63C70000-4A82-4261-95FF-92CF32477861"); //iGrill mini Service

I am able to to connect the device but it will crash the ESP32-WROOM-32U in App authentication phase?

let me know what information is needed to debug more?

[1mckenna]

Sorry for the delay, you'll want to follow the steps outlined here to install the ESPExceptionDecoder so we can get info about whats causing the crash.

Just based on where its failing looks to me like the AUTH SERVICE UUID isn't the same for the mini.

Since I don't have an iGrill Mini device I'll need to see if you can determine what characteristics we'll need to use.
The easiest way to do that will be to

1. Install the Weber iGrill App and pair the device to the phone via the app
2. Install the nrfConnect Android App
3. Once in the App Click on the Bonded Tab
4. You should see your iGrill Mini listed, click Connect
5. It should then go through discovery of the services
6. In the listed services can you take a screenshot or attach all the UUIDs shown.
7. Dont forget to unpair the iGrill device from your phone so you dont run into connectivity issues with the ESP32
8. Once we have all the correct UUIDs for the mini device it should be a simple to get it working.

What version of the esp32 libraries are you using? Same version shown here?

[jysaloma]

I will now try with older and that version you mentioned on that page.

[jysaloma]

Seems to work now on that part but throws exception on setting up probes? (I will also double check the mqtt configs)

Awesome looks like I'll just need to add in a check to see if we're setting up a mini device so we only try to setup one probe.

Can you try commenting out lines 307-324 and see if it runs without crashing?

I just pushed an updated version to the mini branch that should work (or be close). Can you switch to that branch and then try that version and let me know the results.

I switched to that branch. It seems to work but I not get the devices or entities in Home Assistant via MQTT.

I am using Mosquitto broker version: 6.0.1
I setup the #define MQTT_BASETOPIC "homeassistant"
I also enabled the DEBUG logging for mqtt but I not see anything related to iGrill
logs:
homeassistant.components.mqtt: debug

Do I need to create the devices manually or should it create these automatically? Any other idea to try. This is probably another issue though.

As long as you have MQTT Discovery enabled in Home Assistant it should automatically pick up the device next time home assistant is restarted. I've found its easiest to use the MQTT Explorer application to connect and verify everything is showing up properly in MQTT.

Can you try installing MQTT Explorer and see what entries are showing up in there for you?

[jysaloma]

Yes it works now! Sorry my bad. I updated the config file again in AP mode to have the base topic also the same as "homeassistant" than in config.h.

Awesome! Once I get a chance to validate everything still works with the v2 device I'll merge these changes into the main branch and put your name down in the contributions section as the tester for the mini devices.

Thanks!
