Growatt is a Chinese maker of solar inverters, home batteries and EV chargers, sold through Shenzhen Growatt New Energy Technology Co., Ltd. Systems are monitored and controlled through the ShinePhone app and Growatt's cloud server, with a separate GroHome app for Growatt's small smart home devices.
Growatt systems normally report to Growatt's cloud (ShineServer) through a small data logger or built-in Wi-Fi. The apps and most integrations we found go through that cloud, but a local route exists: Growatt's Wi-Fi logger datasheet lists Modbus, and Homey's Growatt app can read inverters over Modbus TCP from one specific dongle. Community tools such as Grott intercept the logger's data to feed MQTT and openHAB.
That suits people who want solar and battery data inside Home Assistant, openHAB or Homey, or who want to remote-monitor a system from one app. It is weaker for local-only control, because the official Home Assistant integration polls the cloud every 5 minutes, local options depend on the logger model and need technical setup, and we found no Matter, Apple Home or SmartThings support.

The main app. Energy monitoring of generation, consumption, storage, battery level and grid interaction, quick device setup, multi-device monitoring and AI-based charge and discharge suggestions from dynamic electricity prices. Published by Shenzhen Growatt New Energy Technology Co., Ltd. The App Store listing does not mention Google or Alexa. The Android link uses the package name shown in a third-party app database, which describes it as Growatt's Google Play app, and we could not load the Google Play page itself to confirm it.
A redesigned beta app for end users with energy flow diagrams, support for inverters, dataloggers, meters and storage systems, dynamic-price battery optimisation and AI customer support. The listing says English and Simplified Chinese only, and one reviewer reported being unable to register in the US. We could not confirm an Android version or how it will relate to the current ShinePhone.
An app for Growatt's smart home devices. The listing describes adding devices, assigning them to areas, and building scenes and timed routines, with voice control through Amazon Alexa and Google Assistant. It names light bulbs, light strips and switches, and the reviews shown mostly report login and registration problems. We found no Android link.

Wi-Fi
Yes
The ShineWiFi-X data logger datasheet lists 2.4 GHz only (802.11 b/g/n) and says the logger sends data to the ShineServer cloud at server.growatt.com every 5 minutes. A community write-up notes the Wi-Fi logger struggled with passwords containing special characters or spaces, and that the author switched to a wired ShineLan-X logger.
Systems report to Growatt's cloud, and the ShinePhone app, Home Assistant's built-in integration and the Growatt cloud mode in Homey all read from it. Home Assistant labels its integration Cloud Polling and says it polls every 5 minutes.
The ShineWiFi-X datasheet lists Modbus RTU over USB to the inverter and Modbus TCP for server communication, with no local access method described. Homey's Growatt app offers a local Modbus TCP mode through a ShineWiLan-X2 dongle with a fixed IP address, updating every 10 seconds, and says other dongles are not supported.
Growatt's THOR EV charger is described as having Wi-Fi, a LAN port and 4G. A community write-up used a wired ShineLan-X logger on an inverter. We did not read an official page listing every logger and its connection.
We found no Growatt Matter announcement or product in the pages we read, including the app listings and a 2022 Growatt interview. We did not run a dedicated Matter search.
The GroHome listing says its devices work with Google Assistant voice control, and a 2022 PV Tech interview says Growatt's IoT devices can be linked to Google and Amazon voice assistants. This is for GroHome devices such as bulbs and switches. We found no page saying inverter or battery data can be controlled by voice.
The GroHome listing names Amazon Alexa voice control, and the 2022 PV Tech interview mentions Amazon voice assistant linking for Growatt IoT devices. As with Google, we found no page covering inverters or batteries, and the ShinePhone listing does not mention Alexa.
No Growatt integration turned up in the pages we read. We did not run a dedicated search.

GroHome ecosystem
Not mentioned
Growatt describes GroHome as a platform that ties inverters, batteries, EV chargers and other IoT devices together, steering surplus solar to batteries, EVs or hot water. PV Tech's THOR article says the charger works with GroHome and can be monitored through ShinePhone, with a PV linkage mode that charges from solar only.
A built-in Growatt Server integration is maintained by the Home Assistant project, not by Growatt. It is cloud-polling and covers solar inverters. Username and password login works with any inverter ShinePhone can control but uses a strict classic API that can lock the account for up to 24 hours if rate limits are exceeded. An API token is the supported method, supports only listed models (MIC, MIN, MOD/MID TL3-XH and several SPH series) and unlocks inverter controls. Home Assistant lists Gold quality and about 4,683 active installs.
A Growatt app on Homey's store lists RM de Gruijter as developer and labels the developer official. It supports Homey Cloud, Pro, Pro mini and Self-Hosted Server, with cloud and Modbus device types for inverters, batteries and meters, but needs a Homey Bridge for every device. We could not confirm whether Athom or Growatt publishes it.
A Growatt binding is in openHAB's add-on list, maintained by the openHAB project. It does not talk to the cloud directly. It depends on the separate Grott proxy, which sits between the data logger and Growatt's server, and the logger must be rerouted to Grott using the Growatt app. Channels are read-only, with rule actions to set battery programs through the Growatt cloud.
Grott is an independent proxy that forwards the logger's data unchanged to Growatt while publishing a copy to MQTT. A community write-up also describes replacing the logger firmware with ESPHome for fully local data, which stops the ShinePhone app working and removes inverter configuration. Experimental Grott Server aims to replace Growatt's cloud server.

Growatt developer API
Unconfirmed
Home Assistant says API tokens can be generated in the Growatt web portal or the ShinePhone app, and calls the token method the supported one. Several integrations use it. We could not open Growatt's own developer documentation, so its terms, rate limits and device coverage are unconfirmed.
