Hi again,
It seems like the Oomis are missing configuration files in the github library you are linking to. I have the same problem with the wallmote from Oomi, but I have found a workaround. I have stopped the homeassistant service and then added the missing configuration in the zwcfg_****.xml file. I found the a thread in for the wallmote here Aeotec wallmote quad zw130.
I have the aeotec version of the same sensor and that works fine.
Br,
JM
