Lutron, makers of smart lighting controls and dimmers, has issued an “important update” for customers who have integrated Sonos products tied to their systems and are looking to install the latest S2 app update from the latter.

Sonos released its new S2 app yesterday for the company’s latest Sonos Arc, Five and Sub Gen 3 products (read our Sonos Arc review here), which can only be controlled with the S2 app. These new 2020 Sonos products launch tomorrow.

While this doesn’t affect most Lutron customers, the company says those with integrated Sonos products linked to Lutron systems may be affected, specifically Caséta, RA2 Select, RadioRA 2, or HomeWorks.

Lutron explained in an email to customers this morning, “if your Sonos system includes products that are compatible with S2 AND products that are not, your Lutron/Sonos integration could be impacted. DO NOT UPDATE TO S2 BEFORE READING THIS FAQ.” Did you read the part with caps lock?

The Lutron/Sonos FAQ document says if all your Sonos products are S2-compatibile, you can update to S2 as Lutron products won’t be affected. The same goes if you don’t have any Sonos products that are S2-compatible.

The only scenario where Lutron products may be affected is if your have a mix of Sonos products compatible with S2 and the original S1 app. There are two options here, says Lutron, with the recommended step is to not update to S2 and keep your system on S1.

The second option which is not recommended is to split your Sonos system into two, with newer products on S2 and older devices on S1. This will cause the biggest impact on Lutron products as

“You will need to reset and re-program your Sonos integration with Lutron, and you will no longer be able to control all of your Sonos devices together through Lutron,” explains the company.

If you proceed with the second option, all existing Sonos programming will be lost from your Lutron system, including scenes, schedules, audio Pico remotes and more that tied in with Sonos products. This means your presets for lighting moods and music with Sonos will be broken.

Lutron will no longer be able to control your Sonos speakers once you re-program your system, as the automatic default will be to the Sonos system with the most devices in it and this can’t be changed, says the company.

While the Sonos S2 update won’t affect all Lutron customers, those affected by the change probably would have liked to have been notified by the lighting company sooner, as there’s no going back once you update a mixed Sonos system to S2.
