I’ve created an app written in NodeJS and Typescript that allows you to create better and powerful automations in Typescript.
It’s easy to install, configure and to start to use.
Here is the repo: https://github.com/danitetus/hass-sidecar
Here is the docker version: https://hub.docker.com/r/danitetus/hass-sidecar
I hope you like it and give feedback if you find it interesting.
