Connecting a temperature sensor to a phone usually means installing an app, fighting drivers and signing up. This Mini App removes all of that: open it in Telegram and you see the sensor's data live.
The pain it solves
A client needs to quickly read temperature and humidity from a device, without installing a separate program or buying proprietary software.
Who it's for
Anyone working with Escort TH-BLE sensors: logistics, warehouses, pharma, climate control.
How it works
The Mini App opens right inside Telegram, connects to the sensor over Web Bluetooth (browser↔device, no app needed), reads temperature and humidity, and shows live values and charts in real time.
Under the hood
React 18 + TypeScript + Vite, the Web Bluetooth API, the Telegram WebApp SDK, Zustand for state. Deployed on GitHub Pages / Vercel, open source on GitHub.
Why it's interesting
Web Bluetooth is a niche, finicky technology: limited support, precise GATT handling. Getting it to a stable, working Mini App is exactly the 'hard pain' kind of work.
