@t1m0 Looks like config.json has been damaged

Funny … I did not change anything. What am I doing now?

hmm
config.json is empty
I took a backup. Now everything seems to run again

next bug
If I change something and want to save this crashes pimatic immediately

@t1m0 Which type of device is it you’re trying to change?

Ping Presence

@t1m0 i have the exact same problem.

I have 5 ping devices and if i change the first two pimatic crashes.

The first two devices were added in pimatic 0.8, dont know why it crashes

fine! Then I am at least not alone

@t1m0 strange thing is that in my config.json the next ping device is exactly coded the same and that one does not crash.

Debug:

20:33:03.858 [pimatic] Recreating "📶 ESP-master"...
20:33:14.718 [pimatic] Recreating "📶 ESP-master"...
node: ../deps/uv/src/unix/poll.c:80: uv_poll_stop: Assertion `!(handle->flags & (UV_CLOSING | UV_CLOSED))' failed.

As you can see, i changed esp-master without a problem and after that the device that crashed.
