Blue gateway 1.7C

A picture is worth a thousand words. Here is new OHS gateway officially named 1.7C. Major difference comparing to 1.7. is 2G modem SIM800C. With four bands GSM support it can be deployed worldwide. And just one remark to relays, I have switched from black Chinese made Omron to blue one's made in Japan. They are slightly more expensive, but somehow cute and blue :).
