Protocols: ZIGBEE^{[1][2][3][6][7][8][9][23][24][33][34][49][56]}

Plans and ongoing costs^{[5][18][26][36][51][58]}

✓ Works without a subscription: Yes.

Vendor account required: Inconclusive — we read the vendor's own setup material and it does not say either way. Treat it as unanswered rather than as a no.^{[15][31][41][60]}

No subscription for motion/automation functions. (Hue Secure camera plans exist elsewhere in the lineup but do not apply to this sensor.)

Maintenance and offline use^[7]

• Batteries: AAA (LR03) x2 — manufacturer-stated 24 months per set
• Works without the internet: Yes — the core function runs on the device or your home network. A vendor cloud may still be involved in remote access.^{[1][7][22][32][48]}
• Official spec lists 'Minimal battery lifetime 2' years on 'Battery type AAA (LR03)'. ⚠ The cell count is no longer an assumption: the spec block now states 'Batteries included 2 x AAA', which retires this record's previous caveat that the count of two was commonly assumed but unverified — re-read 2026-08-09. ⚠ A trailing sentence describing Alexa and Google exposure as riding Hue's cloud integrations was REMOVED 2026-08-22: no source cited on this record supports it — the Signify spec block this note rests on covers the battery, the IP rating, the accessory cap and the works-with lists, and never mentions cloud — and the same unsupported mechanism had already been taken out of this record's Alexa and Google catches on 2026-08-19. Removed rather than re-asserted, and no replacement citation was sought: the absence of support is the finding.
• Security updates: Philips Hue states its security-update commitment for this model as a period rather than a date: security, quality and interoperability updates 'for a minimum total of five (5) years from the date of your purchase from an authorized reseller' — what Signify says it intends under its Philips Hue End of Support policy for lights, devices and accessories other than the Hue Bridge; the policy's summary table counts the same five years 'from the moment Signify stops selling this version of the product' (the document this comes from names no country, so which markets it legally covers is not stated). That is a floor measured from a starting point the manufacturer sets — a launch or a purchase — rather than a fixed end date, so it cannot be placed on a calendar here. We record the commitment as the manufacturer states it, in our words, rather than converting it into a date it did not give. This is a published commitment, not a gap in our research.^{[21][27][39][59]}

Who it's for

Suits homes already running a Hue Bridge that want light-aware motion automation (with temperature and lux readings) inside the Hue ecosystem or Home Assistant.
