All the Tesla alerts you'd set up TeslaMate for — charging, battery, tyres, drives — delivered in Telegram and hosted for you. Live in about 5 minutes.
TeslaMate is the best open-source Tesla data logger there is — free software, beautiful Grafana dashboards, a passionate community. But "free" assumes you run it yourself, and that part is a real, recurring job:
If you enjoy that kind of tinkering — genuinely, self-host it. If you just want the alerts, that's exactly the part we productized.
| Self-hosted TeslaMate | WattsonBot | |
|---|---|---|
| Time to first alert | An evening of setup, plus MQTT/Node-RED wiring for notifications | ~5 minutes in Telegram |
| Monthly cost | Free software + $5–10 VPS + your time | $5 flat, free trial first |
| Maintenance | Updates, migrations, backups, uptime — all yours | All handled for you |
| Push alerts | DIY via MQTT + Node-RED/scripts | 9 alert types built in: charging, battery, TPMS, drives, Sentry, left-unlocked |
| Where you look | Grafana dashboards in a browser | Telegram chat you already have open |
| Stats & history | Full Grafana suite, raw SQL access | 16 chat commands: trips, charts, monthly reports, costs |
| Data & control | Everything on your hardware | Isolated private instance; read-only token you can revoke anytime |
| Best for | Tinkerers who want dashboards and full ownership | Owners who want the alerts, not the ops |
Honestly: if you want the full Grafana dashboard experience, raw SQL access to every data point, and you're comfortable running Docker — self-hosted TeslaMate is excellent and free, and we'd point you straight at it. WattsonBot exists for everyone who read that setup guide and closed the tab.
WattsonBot isn't a TeslaMate clone — it runs the real thing. Every subscriber gets a private, isolated instance of the open-source TeslaMate engine (unmodified official release) with its own database and MQTT broker, plus our notification bot on top. We keep it updated, backed up and running; you get the output in Telegram.
Open t.me/WattsonEVBot and tap Start. No app, no signup form.
Start with the free trial or go straight to Solo ($5/mo). Pay with Telegram Stars or crypto.
Send a Tesla refresh token — read-only, revocable, your password never leaves Tesla's own login page. Two-minute guide here.
Charging, battery, TPMS, drive summaries with cost — all in the same Telegram chat, plus 16 commands for stats and history.
Yes — under the hood it runs the same open-source TeslaMate engine (an unmodified official release) in a private instance dedicated to you. We maintain the servers, updates and backups. Credit where due: the TeslaMate project is what makes this data possible.
No. Nothing to install, nothing to host. If you can open a Telegram chat, you can run WattsonBot.
No. The refresh token grants read-only access to vehicle data. WattsonBot cannot send commands to the car, and you can revoke the token at any time from your Tesla account.
Anytime. There's no lock-in: cancel with /billing, revoke the token, and spin up your own TeslaMate whenever you like.
The Tesla app shows you state when you open it. WattsonBot pushes what the app won't: charging interrupted, low tyre pressure, car left unlocked, Sentry Mode toggles, drive summaries with energy cost — without you having to check.
$5/month for the Solo plan — one car, all alerts, all 16 commands, stats and history. There's a free trial, and you can cancel anytime from Telegram.
Live in 5 minutes. Free trial, then $5/month. Cancel anytime.
