Apollo Automation is a small US company in Kentucky that designs and sells open-source smart home sensors, including the AIR-1 air quality monitor, the MSR-1 and MSR-2 mmWave multisensors and the R PRO-1 presence sensor. The devices run ESPHome firmware and are sold through the company's own shop. Home Assistant is the primary platform, and there is also an official Homey app.
Apollo devices join the home Wi-Fi network and talk to the controller locally through ESPHome, so no vendor cloud or subscription is involved. Home Assistant picks them up through its built-in Apollo Automation and ESPHome integrations, and Homey Pro users can use Apollo's own Homey app.
That suits people who already run Home Assistant or Homey and want sensors that keep working without internet. It is weaker for anyone who wants plug-and-play use with Alexa, Google Home or Apple Home, because we found no direct support for those and Matter was only described as in development.

Apollo's own app for Homey, listed as Apollo Automation Official on the Homey app store. It is not a phone app of its own: it runs on Homey and connects Apollo devices over the local network with the ESPHome native API, without a cloud account. It lists AIR-1, MSR-1, MSR-2, MTR-1, R PRO-1, TEMP-1, PLT-1, BTN-1, PUMP-1 and other Apollo devices. Apollo's announcement of the program is dated 10 July 2025.

The AIR-1 page says the device connects over Wi-Fi to ESPHome on Home Assistant. Apollo's Hubitat and HomeSeer announcement says the devices use Wi-Fi with no cloud dependency. No Wi-Fi band is stated on the pages we read.
Apollo's March 2025 post says Matter support is in development, aimed at SmartThings, Apple Home and Google Home. We found no later page confirming a release.
Apollo's documentation navigation lists a SmartThings Direct Control tutorial, but we could not read it. SmartThings is also named as a target of the planned Matter support.
Apollo is a Works with Home Assistant partner, and Home Assistant has an Apollo Automation integration built on its ESPHome integration. Communication is local push, and devices can be auto-discovered. The listed products include the AIR-1, R PRO-1, MSR-2 and MTR-1. Apollo's AIR-1 page calls Home Assistant the primary platform.
The firmware is ESPHome-based and Apollo describes its products as open source with GitHub repositories. The MSR-1 is described as designed for Home Assistant via ESPHome. The AIR-1 page notes that locally built YAML needs a recent ESPHome version for newer firmware.
Apollo publishes its own app, listed as Apollo Automation Official. It lists Homey Cloud, Homey Pro, Homey Pro mini and Self-Hosted Server under Works on, but also says Homey Bridge required. It needs Homey 12.3.0 or newer and connects locally through the ESPHome native API.
Apollo says the TEMP-1 is compatible through a beta driver on the Hubitat community forum, developed by a community contributor. A March 2025 post also said Hubitat and HomeSeer support for other sensors was coming soon, so the current scope is unconfirmed.
The AIR-1 page says it may be able to work with other platforms through custom configurations or MQTT, but gives no details and describes Home Assistant as the primary platform.
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.
