Zevron — heater control

// Overview

Remote control for coal-fired heaters. The backend collects telemetry over MQTT, monitored through a React dashboard and a Telegram bot.

// What I built

1. 01

   Telemetry: water, coal and air temperature, motor current, RSSI, fire and sensor alerts

2. 02

   Changing a temperature threshold pushes the command to the device instantly

3. 03

   React + TS dashboard: per-branch filter, 24-hour temperature chart

4. 04

   Telegram bot: linked via deep-link or invite code, read-only, stateless
