[@MCsCreations]

Pretty interesting project, dude! Thanks a lot! 😃

[@williamblair1123]

thanks for the video - really helped me get started. This is probably the best video I've seen so far regarding this. Also, where did you get those female headers from

[@Zebsterdk]

I will try to make one. Thanks

[@MauroSedrani]

Thanks!

[@MrBobWareham]

Thanks for the video very informative and helpful I am new to MQTT and want to make my server on a raspberry pi so I can use it to monitor doors and windows plus temperature and humidity so your video was most helpful, but can you make a door sensor as that would help me a lot thanks, Bob

[@rolandsteiner]

Good work, which I'd like to reproduce. However, the code you show in the video is not available on your github.

[@u2bist]

I don't understand why you soldered the sensors to the top of the ESP-01 instead of to the pins on the socket. That's what sockets are for.

[@DIYTechRepairs]

Because i want the pins to be free if i need ed to reprogram it. Easier that way
