I really enjoyed this. So often HA content is aimed at integrating the device, some of us love a bit of detail.

This is very cool, I didn't even know this functionality existed. And you did an excellent job in explaining and demonstrating it. Wow, so clear so concise, I don't know if you do this kind of work professionally, but if you do, I won't be surprised. Definitely gonna play with this sum, I'm not sure exactly how I will use it but I'm definitely gonna add this to my toolbelt. Thank you so much.

Thank you so much for this video, I wanted to express my gratitude for the valuable video and information you recently shared with us. It has been incredibly insightful and beneficial.

In light of the knowledge gained, I am eager to delve deeper into Home Assistant WebSocket API and REST API testing using Postman. I believe hands-on experience in this area will further enhance my understanding and proficiency.

If possible, could you kindly provide a tutorial or guidance on conducting Home Assistant WebSocket API and REST API testing in Postman? Real-time feedback would be immensely appreciated, as it would contribute significantly to the practical application of the concepts learned.

Your assistance in this matter would be invaluable, and I am confident that such a tutorial would not only benefit me but also others in the community who share a similar interest in Home Assistant API testing.

Thank you once again for your time and for sharing your expertise. I look forward to any guidance or resources you may provide.

Thank you. A bit of an eye opener for me. Always great to see different ways of doing things. Got my nuc powered up with home assistant OS. And now ready to go for configuring my devices... Postman, and your advice will definitely come in handy! Not very clued up with WebSockets - as yet - but will spend some time trying to figure it out! Keep up the good work!

Great explanation, sub'd. I would love more "make Home Assistant talk to anything" content like this. Getting started where I have an IOT device that streams data via a get with the data in the URL params, it seems like I need to do something with NodeRed to get this to work but after 20 min of fiddling it seems like it doesnt do it. I cant see anything in the logs, either.

great video as trying to get my autofeeder to work using websockets. My question is that I can use postman following your process but can I fire a websocket command to the sensor using Home Assistant instead of using Postman?
