Your subscription controls how many devices you can connect, how many dashboards you can build, how far back your data history goes, and which notification channels are available to you. ## Choosing a plan Chirp offers three paid plans alongside a free starter tier, plus a Business option for larger setups. Each plan card shows the monthly price and a full feature comparison so you know exactly what you're getting before you commit. | Plan | Price | | ------------ | -------------- | | **Free** | Free | | **Light** | €7.99 / month | | **Pro** | €12.99 / month | | **Max** | €19.99 / month | | **Business** | Contact sales | **If you're just getting started:** The free tier lets you connect a limited number of devices and explore the platform without entering payment details. When you're ready for more, pick a plan and tap **Upgrade Plan** — you go straight to a secure checkout page to finish, with no extra confirmation step in between. Your new plan's limits apply as soon as it's active. **If you already have a plan:** Your current plan is highlighted in the comparison. To switch, tap a different tier and you're taken straight to checkout. To manage billing details, download invoices, or cancel, tap **Manage my subscription** — this opens your billing portal where all payment management happens. ## What each plan includes The plan comparison shows the limits for each tier across: * Number of connected sensors * Number of custom dashboards * Data history retention (how many days of sensor readings you can query) * Notification channels (email, SMS, push) * Rules engine capacity * Support level ## When you reach a plan limit Your plan sets how many of certain things you can have at once — and dashboards are the one you're most likely to bump into. When you've built as many custom dashboards as your plan allows and try to add one more, Chirp lets you know you've **reached your dashboard limit** and tells you how many your plan includes. You have two easy options: remove a dashboard you no longer use to free up a slot, or tap **Upgrade Plan** to move to a tier that allows more. The same idea applies to the other limits — connected sensors, rules, and history — so if you find yourself running out of room, it's usually a sign it's time for the next plan up. ## Growing beyond the home plans If you're connecting devices across multiple locations, managing sensors on behalf of others, or running a commercial installation, the home plans may no longer be the right fit. In that case, the next step is **Kilo IoT Server** — a platform built for commercial and multi-site deployments, with higher device limits, multi-organisation support, and features designed for operational teams. The **Business** plan card in Chirp includes a **Switch to Kilo** option. Tapping it takes you to Kilo IoT Server, where you can start a deployment at a scale suited to your needs. There is no automatic migration of your existing data — Kilo is a separate platform with its own account. To explore Kilo IoT Server directly, visit [app.kiloiot.io](https://app.kiloiot.io). ## SMS top-up If your plan includes SMS notifications, you can purchase additional SMS credits from this page. Enter the number of credits you need, review the cost per message, and confirm the purchase. Credits are valid for one year from the date of purchase. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.chirpwireless.io/account/subscription.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
