Hi,
I have already searched this issue and found minimal solutions - I've changed the dimming type as a test (I've tried both leading and trailing edge, without change in behavior) which seems to be the only fix people have found.
I've then reached out to my supplier in Australia - who has requested I make a support thread instead of relying on the knowledge base & search function. So I am now making a thread to request support for an overheating issue.
I had these dimmers installed on a few switches by an electrician - the 2 circuits I'm specifically having trouble with overheating on are outdoor LED uplighters. One has a ~70w load, one has a ~12w load.
The overheating error occurs between 35 seconds and 5 minutes after turning the lights on.
These are the status reports from the 2 circuits with overheating issues (from a few nights ago when I sent my original email)

This is the status from a circuit of down-lights that is not having issues, in case it helps.

I have noticed they overheat much faster when being dimmed. this might not be correct. The outdoor circuit set itself to 10% dimming when I calibrated it just now, so I thought I'd let it run and see what happens. I'll update if I see a pattern again.
I have calibrated both several times during troubleshooting, but have literally just observed it changing from "calibrated":true to "calibrated":false in front of me a minute ago.
