Tigo Energy is a US solar technology company, founded in 2007 in Silicon Valley, that makes module-level power electronics: TS4 optimizers that handle shade, monitoring and rapid shutdown. It also sells Energy Intelligence monitoring software and home inverter and battery systems, all managed through the Tigo Energy Intelligence app and web portal.
TS4 units talk wirelessly to a Tigo Access Point (TAP), which is wired by RS485 to a Cloud Connect Advanced (CCA) gateway. The CCA reaches the internet over Ethernet, Wi-Fi or optional cellular and sends data to Tigo's cloud. Outside integrations either use Tigo's paid cloud API or read the CCA locally through community projects.
That suits solar owners and installers who want panel-level monitoring and who may add Home Assistant or Homey for dashboards. It is weaker if you want an official, local, no-cost data feed: the API needs an EI Premium or Professional subscription, and community reports say newer CCA firmware locks local web access.

The mobile app for laying out, commissioning and monitoring Tigo systems. It shows a single system or a fleet, module-level detail and history, and alerts, and installers can connect to the CCA over local Bluetooth to configure it and set up its internet connection. It needs iOS or iPadOS 15 or later and is published by Tigo Energy, Inc. The web portal is at ei.tigoenergy.com, and Tigo also offers a direct Android APK download. The Android link below uses a package name taken from a third-party app-tracking page, and we could not load the Google Play page itself. A separate App Store app called TIGO Monitor is an unrelated security product from another publisher.

Connection
Proprietary wireless (TS4 to TAP)
Yes
Tigo's CCA page says the CCA connects to the Tigo Access Point over an RS485 cable and the TAP communicates wirelessly with the TS4 units. The page does not give the wireless frequency.
The Tigo Energy Intelligence listing says installers can connect over local Bluetooth to the CCA to configure systems and set up the internet connection. Tigo's CCA page does not mention Bluetooth.
The CCA page says inverters, batteries and building meters can connect to it, without naming Modbus. Tigo says EI supports more than 20,000 equipment types, including third-party inverters, meters and batteries.
A community forum thread asking for a Tigo integration suggests there is no built-in one. Community options include two custom integrations by one author: Tigosolar-online, which uses the paid Tigo API, and Tigosolar-local, which reads a CCA on the local network every 30 seconds or so. The local integration says newer CCA firmware (4.0.4 or later) password-locks the local endpoints and offers a slower cloud fallback. A separate taptap add-on taps the RS485 line between TAP and CCA and publishes to MQTT. None is maintained by Tigo.
The Homey store lists a Tigo Energy app under the developer label RM de Gruijter Official, and the developer's forum post calls it an official replacement sponsored by Athom. Tigo's own involvement is not stated. It needs an EI Premium or Professional subscription and a Homey Bridge, supports Homey Cloud, Pro, Pro mini and Self-Hosted Server, and reports power and total generation for an inverter. The developer says the Tigo API covers inverters only, so battery control is not supported.

Tigo API
Official
Tigo has a REST API (v3). Tigo's support article says it needs a Premium data subscription and that data is read from Tigo's servers, not from the logger, using a bearer token obtained with your login. Tigo's page lists EI Premium at $20 a year per site of up to 35 modules, with API access and data export. The API terms, effective 17 June 2024, cap use at 100 requests per minute per account and give no support entitlement.
Tigo's pages we read describe no local API. Community projects fill the gap: Tigosolar-local polls the CCA's local address, and taptap reads the TAP-to-CCA RS485 traffic through an RS485-to-Ethernet converter. A taptap author reports that newer CCA firmware closed local web access, making the RS485 route more durable.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
Common questions about Tigo Energy
Does Tigo Energy support Matter?
Unconfirmed. No Matter support appears on the Tigo pages we read. We could not confirm either way.
Does Tigo Energy work with Home Assistant?
Yes, through a community-built integration. A community forum thread asking for a Tigo integration suggests there is no built-in one. Community options include two custom integrations by one author: Tigosolar-online, which uses the paid Tigo API, and Tigosolar-local, which reads a CCA on the local network every 30 seconds or so. The local integration says newer CCA firmware (4.0.4 or later) password-locks the local endpoints and offers a slower cloud fallback. A separate taptap add-on taps the RS485 line between TAP and CCA and publishes to MQTT. None is maintained by Tigo.
Does Tigo Energy work with SmartThings?
Unconfirmed. We did not search SmartThings specifically and found no Tigo integration. We could not confirm.
Does Tigo Energy work with Homey?
Yes, officially. The Homey store lists a Tigo Energy app under the developer label RM de Gruijter Official, and the developer's forum post calls it an official replacement sponsored by Athom. Tigo's own involvement is not stated. It needs an EI Premium or Professional subscription and a Homey Bridge, supports Homey Cloud, Pro, Pro mini and Self-Hosted Server, and reports power and total generation for an inverter. The developer says the Tigo API covers inverters only, so battery control is not supported.
Does Tigo Energy work with Hubitat?
Unconfirmed. We did not find a Hubitat driver for Tigo. We could not confirm one exists.
