I’ll add my own experience here, nothing new but maybe worthwhile to summarize for someone who’s thinking about getting this device or just wants a quick resolution:
- It’s not possible to set correct associations with the current Z-Wave stable or snapshot versions → automatic reporting does not work out of the box.
- Polling does work, so it is possible to get new values every X seconds/minutes using a rule - you won’t get all the benefits of reporting though.
- The associations can be set through a software called Z-Wave PC Controller. I’m confused about where to download this officially, but unofficial source is mentioned here.
It was a bit scary doing this without really knowing what I was doing, but I got it working by following the instructions from Austris_V. Newer version of the program looks different, but the same options are there.
Other than that the HEM has been working great (for 30 hours at least..) and it has good options for finetuning the reports. Hopefully whatever needs to happen to get the associations working without 3rd party software happens, but unfortunately my knowledge on this area is not enough to further that cause.
