Not unless you find a used LK IHC controller. It has to be either a Visual 2 or 3 controller. They have Ethernet network interface and an API that can be connected to HA. But if it's just 1 outlet and 1 switch, it's probably easier and cheaper to replace them with Zigbee or HA complaint components. An electrician can replace them in less than 30 min.

LK IHC wireless does not use the Zigbee standard. They use wavenis as far as I remember. Wiser uses Zigbee, but there are different opinions about whether they can connect with other Zigbee products or not.
