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 ;-)
