ups monitor

ups status monitor for Raspberry Pi Openwrt

图片

connect (openwrt raspbeery pi需要先安装i2c内核驱动的支持)

Raspberry Pi I2C interface

hack （如果获取ups连接到树莓派后，用的是哪个地址）

opkg install  i2c-tools

i2cdetect -y 1

默认设置的地址为 0x42(需要修改 /ina219.go#L44)

	// create the sensor Opts
	sensorOpts := ina219.Opts{
		Address:       0x42, // ina219 ic2 address
		SenseResistor: 100 * physic.MilliOhm,     // 0.1Ohm
		MaxCurrent:    1000 * physic.MilliAmpere, //1A
	}

how to build

Install golang in the host (the host system must by Linux or Mac)

just run make to build the ups_monitor

make

Install ups_monitor to Raspbery Pi

192.168.xx.xx is the ip of you RPI

scp ups_monitor root@192.168.xx.xx:/tmp

Run ups_monitor on Raspberry Pi

connect RPI with ssh

cd /tmp
mv /tmp/ups_monitor /usr/bin/ups_monitor
