Description

Smart Home Automation - Modbus 8 x SSR output

I prepared my Smart Home Automation project using some relay output modules. Unfortunately those modules didn't work very well because inductance load (even if I used snubber). So I prepared my own module using STM32F030 and G3MB-202P SSRs.

Those modules are running since more then year without almost any issue.

I will add source code to github repository soon - after some code cleanup ;-)
