Hello! I’ve too many dw2 devices… and I bought the I host for this 
do you know when this function could be upgraded? Thanks
As far as I know, unfortunately you can’t do anything about it. DW2-WiFi is only a “cloud” device, i.e. its operation is only possible via the ewelink application or WEB panel.
I am also afraid that they may not plan to add DW2-WiFI to iHost, it would probably require an improved firmware version to add DW2 LAN options. Otherwise, communication will always take place via the cloud.
However, if you mean DW2-RF, it should probably be added via HUB.
