Thermostat Monitor

About The Project

A full-stack IoT telemetry and control system that logs temperature and heating relay status from Salus iT500 thermostats and Tuya sensors across several properties.

Surfaces operational data three ways: a responsive Progressive Web App with live readings and interactive charts, a Discord bot for fast chat queries, and an automated continuous CSV data store.
