The temperature tab didn't work before updating just now, it just showed an empty page. Edit: apparently it doesn't handle "stale" devices very well. Got some old laying around for historical purposes, but those don't get any updates any more. Can you send (PM) me a view-only account so i can debug ...

Another option perhaps could be to make the code available so one could host them themselves?

No idea how domoticz stores such credentials. But, since http is used to talk with the camera, the communications are in plain text and can thus easily be sniffed using tcpdump/wireshark/etc. A third option could be performing a factory reset on the camera itself.

Still curious why the "old" cable would work with HyperTerminal. Guess we'll never know

Yeah, had overlooked that part. You sure you used same serial settings? Wouldn't surprise me if HyperTerminal would play some tricks under the hood. Step 1 would be to get it to work though cu/screen/whatever command line tool. Only once that shows proper data, then try to get it to work within ...

Sounds like the wrong cable. Like with no or wrong resistor in it. That resistor gives a signal to the smart meter to have it actually report data.

Edit: scratch that. Overlooked the successful test on Windows.

The use of copytruncate doesn't require a restart. It does involve a race condition which could lead to loss of (log)data. Any data written between the copy and the truncate will get lost.
