My current setup is a TP-Link wireless extender. From that I have my own little network that connects my computer, wireless devices and a Raspberry Pi 4. The RPi4 runs the Home Assistant OS for my small network of lights and switches. The TP-Link extender does not have enough memory to support OpenWRT which means I am dependent on the proprietary android app to configure it.

I thought I could use the integrations in HA to add OpenWRT and Pi-Hole but it looks like those integrations are for communicating with instances and devices not within the HA operating system.

What I was hoping to accomplish was to run HA, OpenWRT and Pi-Hole on the same RPi4 device and re-use the TP-Link extender elsewhere in the house to serve ad-blocked internet that extends beyond my little network of devices.

Would running multiple services like this be too demanding for the RPi4? And if it is possible, where is a good place to start?
