I guess Din Rail is nothing for you since you are located in the U.S.
By the way where are you from? I lived for 3 years in Hockessin DE

Hi Thomas, I am using: A logic level converters to convert the 3.3 to 5 Volts to control my relais. A PCF8574 board to get 8 ports for my relais. I have not found a 8 relais board with I2C communication. Make sure, that you have a reasonable size transformator. You may easily kill it, if undersized....

Hi janjoh

I like your Plugin. After some work with the module I did some reasearch to stabilize the Measurements and to shorten the measurement cycle. Before adding anything to GitHub, I would like to get in touch with you first.

Best Regards
Stefan
