Chargee

Sparky has a built-in local API that lets you read P1 data directly on your home network, without going through the Chargee cloud. This is useful if you want to integrate Sparky with your own software, home automation systems, or dashboards.

The local API is enabled by default from firmware version 95 on Sparky and version 105 on Flint. Check whether the API is active via Profile &gt; Address &gt; My Home &gt; Local API.

<b>Discovering Sparky on your network</b>

Sparky and Flint are automatically discoverable via mDNS (also known as Bonjour or Zeroconf). You don't need to know the IP address. Use the following command to discover Sparky <code>dns-sd -B _chargee_p1._tcp</code>. Sparky is also reachable via the legacy service on port 3602.

Want to use Sparky as a drop-in replacement for another P1 meter without software changes? Enable compatibility mode via Profile &gt; Address &gt; My Home &gt; Local API &gt; Previous P1 meters. This enables legacy mDNS broadcasting.

For all parameters, example responses and advanced options, download the full API documentation.<br>​

{appName} in 60 seconds

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.

`GET /api`	basic device information (firmware version, serial number, API version)
