In various embodiments, techniques are provided for utilizing a WPAN (e.g., BLE) and an in-home LAN (e.g., Wi-Fi network) together to provision and/or configure hardware elements of a home automation system. In one embodiment, a first WPAN-discoverable hardware element (e.g., a host controller) of the home automation system advertises its presence on a WPAN. The first WPAN-discoverable hardware element receives user-provided network credentials from a mobile app, which are used to configure the first WPAN-discoverable hardware element on the in-home LAN, and which are stored in a storage device of the first WPAN-discoverable hardware element. To provision a second WPAN-discoverable hardware element (e.g., a device) of the home automation system on the in-home LAN, the first WPAN-discoverable hardware element transfers the network credentials back to the mobile app via the in-home LAN, and causes the mobile app to forward the network credentials via the WPAN to the second hardware element.
