Will Kasa add HomeKit support?

TP-Link has not announced any plans for HomeKit support on the KL135 or other Kasa bulbs. Their HomeKit-compatible products are limited to a few specific models in the Tapo range, not Kasa.

Can I use Kasa with HomeKit via Home Assistant?

Yes, indirectly — Home Assistant's Kasa integration plus its HomeKit Bridge add-on exposes Kasa devices to Apple Home. But this requires running Home Assistant on dedicated hardware and adds latency. Not recommended for most users.

What's the cheapest bulb that does work with HomeKit?

The Nanoleaf Essentials A19 at around $15 is the cheapest genuinely HomeKit-native bulb we've tested. It also supports Thread for sub-200ms response.

Does the Kasa KL135 work with Apple Home (HomeKit)?

⏱ 3 min read

Short answer: No — the Kasa KL135 does not support Apple Home (HomeKit). TP-Link's Kasa range is built for Alexa and Google Home only. There's no HomeKit firmware, no Bridge that exposes Kasa bulbs to HomeKit, and no plans announced for HomeKit support. If you need an Apple Home–compatible budget bulb, see our alternative below.

Why it doesn't work

HomeKit compatibility isn't something a bulb can be "patched" into — it requires Apple-certified firmware and an HMI (HomeKit Accessory Protocol) implementation that TP-Link chose not to build into the KL135. The bulb communicates over WiFi to the Kasa cloud, which speaks only to Alexa and Google Home APIs.

There is one indirect path — running the bulb through Home Assistant with a Kasa integration, then exposing Home Assistant to HomeKit via its HomeKit Bridge add-on. But this requires running a Home Assistant server, isn't officially supported by TP-Link, and adds latency that defeats the purpose of buying a budget bulb.

What we measured (Kasa on its supported platforms)

The KL135 itself is reliable — these are our 30-day study results on Alexa and Google Home:

Metric	Result
Uptime	97.4%
Response time	400ms (avg)
Hub required	No
Protocol	WiFi 2.4GHz

If you've already bought one

The Kasa KL135 still works perfectly with Alexa and Google Home. Set up via the Kasa app, then enable the Kasa skill in Alexa or link Kasa in Google Home. If you don't have an Apple Home use-case the bulb is a strong budget choice — our 30-day testing rated it 97.4% reliable.

Recommended Apple Home alternatives

If HomeKit is a requirement, two genuinely better options:

Nanoleaf Essentials A19 (~$15) — Thread + Matter native, sub-200ms response, full HomeKit support. Comparable price.
Philips Hue White (~$15) — needs the Bridge ($60 one-time), but unlocks the most mature HomeKit lighting experience available.

Our verdict: Don't buy the KL135 for an Apple Home setup. Spend the same on Nanoleaf Essentials for native HomeKit + Thread, or step up to Hue for ecosystem maturity.
