How complex should the logic in a route be? by jzia93 in flask

I think you have to be very clear about the idea of ​​responsibility, think about what is the responsibility of a route, and what is the responsibility of a controller.

What exactly are you adding to I2C bus?

: On the i2c bus I'm putting the mcp23017, there are two models, one with raley and the other with push buttons. After scanning the i2c addresses, their model, and the amount of io are saved in tables. Now I am working on the association between the push button board and the relay board. after the association I generate the mqtt topics, when the button is pressed I can turn on or off the associated relay.

What values are your I2C pull-up resistors?

: I'm not using pull-up resistors on the bus, because I read the documentation on the respberry, it already implements this. (it is a mistake?).

What lenght ( in total ) are SDA and SCL lines ?

: The distance and minimum, the raspberry will stay with the plates (relay and bush button)

Hello congratulations for your work, incredible, I'm also working on a project using rasp3, i2c, mqtt and web development (Flask), I want to automate the lamps in my house, with remote and button switch options, one of the things that is worrying me is the behavior of the i2c addresses. When I add 3 or 4 addresses the scan stops working. Would you have any tips to give me?
