Passing values from a networked RPi (without HASS.IO) to a HASS.IO RPi via MQTT

[VDRainer]

Here’s an example with a bash script.

Check remote RPi temperature

I’m using mqtt sensors for this. Install mosquitto clients on your remote pi run the command or a script with crontab every 2 minutes publish the values to mqtt topic create mqtt sensor in ha Example script: #!/bin/bash MQTT='192.168.123.123' TOPIC='home/sensors/minibian/i2c_bus' PAYLOAD=$(/usr/sbin/i2cdetect -y 1 | egrep '^20' | cut -d' ' -f2-9) /usr/bin/mosquitto_pub -r -t "$TOPIC" -m "$PAYLOAD" -h "$MQTT"
