Operwrt based MQTT monitor- based on influx chronograf and kapacitor
to conserve space i left out influx software just ssh in 169.254.10.250 ( or use the dhcp assigned address from your router) ssh root@169.254.10.250 ( blank password) and install influxdb ( using 1.6.2 as they change something in the new version that made it incompatable for some reason) -- i forgot install ca-bundle ca-certificates on image please install first then run
wget https://dl.influxdata.com/influxdb/releases/influxdb-1.6.2_linux_armhf.tar.gz
tar xvfz influxdb-1.6.2_linux_armhf.tar.gz
wget https://dl.influxdata.com/chronograf/releases/chronograf-1.7.5_linux_armhf.tar.gz

the format for sending MQTT is as follows
mosquitto_pub -t 'incoming/OpenWrt/mqtt-Energy/power-grid' -m 'N:21.5'
mosquitto_pub -t 'incoming/OpenWrt/mqtt-Temp/temperature-greenhouse' -m 'N:21.5'
mosquitto_pub -t 'incoming/OpenWrt/mqtt-Humidity/humidity-greenhouse' -m 'N:21.5'
mosquitto_pub -t 'incoming/OpenWrt/mqtt-Flow/flow-heatpump' -m 'N:21.5'
mosquitto_pub -t 'incoming/OpenWrt/mqtt-Pressure/pressure-heatpump' -m 'N:21.5'`
you can change the "hostname" OpenWrt to what ever you like you can use it to develope sub groups but if if you do not use at least one that matches the host name of the device - it will no display rrd graphs with in the openwrt statistics but they will be captured and sent to influxdb
mosquitto_pub -t 'incoming/Garage/mqtt-Pressure/pressure-heatpump' -m 'N:21.5'`
mqtt-Energy, mqtt-Temp, mqtt-Flow and mqtt-Pressure are the the current fixed catagories for displaying in openwrt. you will need to use one of these unless you add in your own catagory- the only prequisite is that it starts with mqtt-XXXXX
power, temperature, humidity, flow, and pressure is the typedb used by collectd you will need to use any of the assigned typedb listed in collectd. grid, greenhouse and heatpump are descriptions you can use whatever you like here..
it creates a data base based on the MAC of the orange pi in the influxdb - then the value is stored as Mac-"hostname"- type -description
you can use one orange pi zero as the influxdb server and other as one as remote nodes just edit Sendinflux.pl to have the ip or domain of the remote location these remotes will be based on thier MAC so there will not be any data overlapping - every thing is automactic and in new MQTT ot nodes will automatically add it data to the influxdb..
