In this video, I give a brief introduction to the EMS-ESP project and show how I use an EMS gateway to push data from my Worcester Bosch Greenstar 8000 boiler into Home Assistant. If you've ever wanted to know what is happening inside your boiler, this might be interesting. It is easy to install and configure and I've been using mine reliably for over two years now.

The project is on GitHub - https://github.com/emsesp/EMS-ESP

I picked up my EMS gateway from - https://bbqkees-electronics.nl/produc....

Service from this company is brilliant. They made a mistake with my order, mixing up with somebody else, so they refunded me 50% and arranged a new unit to shipped to me.

Video Notes:
Sound levels are much better in this video. I've started using the CinemaP3 app on my iPhone and it gave me a better idea of the sound level. I also learned that the gain control on my Rode Wireless Go II doesn't have any effect when it's connected via USB. You have to adjust this on the computer!
