Sensor Data from Raspberry PI to HA on Intel NUC

[broberts (Brett Roberts)]

Hi all, I am relatively new in the Home Assistant community but am hooked already.

One think I am trying to do is connect the data I am collecting around temperature, humidity and light from my raspberry pis and send to my HA. I am running DHT11 sensors with a python script that is logging temp and humidity data.

I figured I need to use MQTT to get the data over to my HA that is sitting on an Linux instance on an Intel NUC. Does anyone have any good YouTube videos or docs that can walk me though how to do this?

Someone has already done the hard work for you:

flyte/pi-mqtt-gpio

Simple to configure with yaml. I’ve been using it reliably for digital i/o for a couple of years.

Thanks for this! And this will help me send messages from remote Pi’s? i.e I have a pi in my office collecting temp data, will this help me in pushing the data from that pi to my HA instance on a separate device?

I’m using bash scripts and mqtt sensors for this.

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"
