Tasker 6.2 introduced the Matter Home Automation actions.

These actions provide direct home-automation support without the need of any third-party services.

You can add your devices and control them in Tasker directly this way, but they have to support the Matter standard.

By installing Home Assistant on your PC/Mac/Raspberry Pi etc, you can then import this project into Tasker to be able to control your home automation setup from Tasker.

This allows you to control any device in your home as well as receive status updates from the devices in Tasker. For instance, you can trigger a Tasker profile when a light turns on in your home.

This is by far the most comprehensive solution that gives you the most dynamic and complete control over your home automation, but you do need to have Home Assistant running on your home network.

You can use AutoVoice to easily trigger Alexa routines from Tasker so you can control your home automation devices that way.

You don't need to have an Amazon Echo for this to work and can get it up and running in 5 easy steps.

This has the advantage of working even if you're outside your home network, if you wish, but isn't as flexible as the other options.
