Did anybody has such issue (mentioned above) to help me where to look for a solution?
The locations you mentioned are correct, but the results are unexpected.
Regarding the Home Assistant log snippet you shared, it appears to be related to the default HASS “Lovelace” dashboard and a custom “Mushroom” extension. It’s not clear to me where you grabbed that from though? Either way, that’s not relevant for our particular analysis – we can circle back to it, but if things are failing before the command is ever sent, we might need to focus elsewhere
When you send a command with the Custom Tile, I would expect that a relevant network request entry would show up in the Network tab of your browser Developer Tools. Here’s a brief example showing where I see the setLevel command successfully sent for a normal dimmable light:
If you don’t see anything in the network tab, then I would at least expect to see some sort of warning or error in the console tab. Note that you may want to enable all the logging levels:
It would be more helpful to know exact details of what capabilities and commands your device supports and one (or more) of the specific configurations you tried in the tile.
You can find the details about the device in SharpTools too:
- Open your SharpTools User Page
- Tap the
...next to the location in question - Scroll down and tap the device in question
- Share screenshots or highlight and copy-paste the relevant details about the device.
Note: I would also switch the ‘Show Advanced’ toggle in the top-right corner and share the Doc ID as I can take a closer look at the details reported for the device.
