ntfy, also from your own server

ntfy is a free push service: you subscribe to a topic in the ntfy app, and everything sent to that topic arrives as a notification on your devices. With the ntfy node, Bellchain sends alerts there, on ntfy.sh or on your own ntfy server. ntfy comes with the Pro plan and up.

Setup

1. Install the ntfy app (Android, iPhone) or open your server’s web app.

2. Subscribe to a topic with a name nobody guesses, such as bellchain-7Kq2xW9. Anyone who knows the name can read along.

3. Only on ntfy.sh: create an account with a paid tier there and create an access token under Account (starts with tk_). Without a token, ntfy.sh does not work, see below.

4. Drag the ntfy node onto the board in the editor, enter server, topic and, if needed, the token, and pick the priority.

Why ntfy.sh needs a token

ntfy.sh counts its free quota per IP address. All of Bellchain’s alerts come from the same address; without an account of your own, all Bellchain users would share 250 messages a day. With the token of an account with a paid tier, ntfy.sh counts your own quota. On your own ntfy server you only need a token if the topic is protected.

Priority

Priority	Effect on the phone
Min	no sound or vibration, only in the list
Low	no sound, collapsed on some devices
Default	sound and vibration like other apps
High	long vibration and a pop-over notification
Max	very long vibration; depending on the phone’s settings even in “Do Not Disturb”

What the alert shows

• Title: the chain’s name, with 🔔 in front (🧪 for test alerts).
• Text: your message, the values when it fired, pair, timeframe and time.
• Tapping opens the chain in Bellchain; the buttons Chart and Open on the exchange lead to the pair’s chart and to the trading page of the exchange from the candle.
• Scanner: if several coins of a scanner fire at the same candle, one message lists them all, one line per coin; a tap opens Alerts filtered to the scanner.

Note

Topic and token stay empty when you export a chain; the history shows only the server and a short fingerprint of the topic. Your own server must be reachable from the internet via https; Bellchain does not accept addresses on your own network such as 192.168.….
