Donate to support Open HardwareThe project is at a **final stage of development. At the moment, a prototype and a working program based on my research on the stable operation of devices without a controller and gateway is ready.** - Happy Standby Node :) | MyS Network Scanner (4 sec.)
In micro network mode devices do not need any gateway or controller. Efficiency remains 100% +mad speed of working off of commands))). As soon as the gateway or the controller again deign to appear in the home network, such devices will immediately know about it and again begin to send some information to the controller(continue interaction).

FTDI and ICSP header for programming
Automatic network search
When the load is switched on, the ssr relay starts, after 100 ms the electromagnetic relay is switched on and ssr is turned off. Such a scheme to ensure the operability of the relay electromagnetic relay, which greatly increases the service life.
The operating modes of the relay are implemented, thanks to the joint operation with the ACS712 current sensor. For example at a load of 100w only the ssd relay will turn on, the electromagnetic will not turn on ....
