DIY WiFi Temperature sensor for smart home

I used Tabler, JS and SSE for dynamic updating of readings.

Install server

1. Build server

cd server
make build

2. Deploy to Raspberry Pi 64-bit

scp bin/temperature-sensor-arm64 pi@raspberrypi.local:/home/pi/bin/temperature-sensor
scp temperature-sensor.service pi@raspberrypi.local:/home/pi/bin/

3. Launch service on Raspberry Pi

sudo -s
mv temperature-sensor.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable temperature-sensor
systemctl start temperature-sensor

check

systemctl status temperature-sensor
journalctl --namespace=temperature-sensor -f
