If you get your hands on an Insteon 2245-222 hub, you can add X-10 devices to it with the Home Assistant integration. I don't like their integration vs the Insteon integration that was created for use with Hubitat (which I personally use with my Insteon dimmers), but the Home Assistant integration is good to have for adding and configuring devices.
The Hubitat integration doesn't add devices to the hub, but it can control Insteon devices and listen to events from them. I have no way of knowing for sure if it would do what you need for X10 since I only own Insteon, but it might be a starting-point if you're not able to use it directly with X-10 devices.
Some additional discussions and resources , as X10 is a question that pops up every so often.
