Hi,
It is not fake news that iHost works locally.
But there are numerous limitations and some essential conditions that are necessary and even mandatory for the devices to work locally.
iHost is a Zigbee hub, but it is even now much inferior to a Zigbee Bridge Pro. With the help of some Add-ons, iHost can locally control only compatible WiFi smart devices that have LAN control. Non-Sonoff devices that can be controlled by iHost are mostly Zigbee devices.
If you want automatic scenes to work locally, they must be added and saved locally on iHost. Unfortunately, this aspect of the local scenes was a determining reason why I gave up on iHost due to the appearance of more or less complex problems almost with every update. The update solved one problem and created 2 others.
If you have stable internet and an average router and want stability in the operation of smart devices, I recommend using the eWeLink APP and the cloud service.
