Bash script that allows to query several MijiaV2 sensors one by one and the information is sent to influxdb.

2 scripts available, the poller and the init.d.

• Update the raspbian distribution : sudo apt update & sudo apt upgrade
• update the firmware : sudo rpi-update

• copy the files directly into their respective places and make them executable :

curl https://raw.githubusercontent.com/jbsky/MijiaV2/master/sbin/mijiav2 -o /usr/local/sbin/mijiav2

curl https://raw.githubusercontent.com/jbsky/MijiaV2/master/init.d/mijiav2 -o /etc/init.d/mijiav2

chmod +x /usr/local/sbin/mijiav2 & chmod +x etc/init.d/mijiav2

• change addMAC , please quote the addresses : ex: addMAC = ("AA:BB:CC:DD:EE:FF" "11:22:33:44:55:66")

• Add label corresponding for each MAC address, of course with the same constraints. : ex: ("Vitre\ Salon" "Salon" "Chambre\ Mathilde" "Chambre\ Parent")

• change influxDB IP : influxDB="192.168.10.182:8086"

• change the name of the influxDB database : _db="temperature"

• Simply as a service : sudo systemctl start mijiav2.service

• Enable the service : sudo systemctl enable mijiav2.service

It is a simple solution to capture data from these small sensors from Xiaomi.

It doesn't wait stupidly after a timeout, this is made possible by a file that counts lines every second.

no multiple parallel connection, no threading. Without saying anything stupid, I don't think the raspberry's bluetooth supports it.
