Quick answers
- Is the Shelly 1 Gen3 Matter certified?
- Yes. MatterCatalog matches it to CSA Matter certificate CSA25013MAT44901-24, certified Jan 15, 2025.
- Does the Shelly 1 Gen3 work with Apple Home or HomeKit?
- Likely. It is Matter certified (certificate CSA25013MAT44901-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Apple Home on a page we hold. Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. Apple’s Matter page lists outlets among the accessory types the Home app supports.
- Does the Shelly 1 Gen3 work with Google Home?
- Likely. It is Matter certified (certificate CSA25013MAT44901-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. Google’s supported-device-types page lists the On/Off Plug-in Unit type.
- Does the Shelly 1 Gen3 work with Alexa?
- Likely. It is Matter certified (certificate CSA25013MAT44901-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold. Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does.
- Does the Shelly 1 Gen3 work with Samsung SmartThings?
- Likely. It is Matter certified (certificate CSA25013MAT44901-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named SmartThings on a page we hold. SmartThings adds Matter devices through the SmartThings app and a Matter controller.
- Does the Shelly 1 Gen3 work with Home Assistant?
- Likely. It is Matter certified (certificate CSA25013MAT44901-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Home Assistant on a page we hold. Home Assistant says: “Adding a new Matter device only works in the Home Assistant Companion app.”
- Does the Shelly 1 Gen3 use Thread or Wi-Fi?
- Wi-Fi. Its catalog record lists Wi-Fi, so it joins your Wi-Fi network and does not need a Thread border router. You still need your platform’s Matter controller.
- Does the Shelly 1 Gen3 need a hub or a Thread border router?
- No hub of its own and no Thread border router: it joins your Wi-Fi network. You still need your platform’s Matter controller (a smart speaker, display, streaming box or hub), though Apple says an iPhone using iOS 18 or later can add Matter accessories without a home hub.
- When was the Shelly 1 Gen3 Matter certified?
- The CSA certified it on Jan 15, 2025 (certificate CSA25013MAT44901-24). That is its certification date, not a retail release date, which MatterCatalog does not state.
- Where can I buy the Shelly 1 Gen3?
- MatterCatalog has verified store links for it at Amazon and Newegg. Check the current price, model and pack size at the store.
