iHost Pairing with Current Devices and Remote Access

I currently have dozens of Sonoff devices, from Basic R2 to MiniR4 and a sonoff Zigbee hub. If I add the ihost hub, do I have to repair my devices individually or will they be recognized by the ihost hub effortlessly? Also, will I still be able to access my devices remotely through the ewelink app?

You don’t need to re-pair the devices, please check this instruction to sync the WiFi LAN device from eWeLink APP.

eWeLink Smart Home add-on:

Be sure that the WiFi devices are on the same LAN with iHost.
