Does the Aqara LED Bulb T2 E27 allow enough leakage current for the Aqara H1/H2 No-Neutral switches to stay powered?

Hey everyone,

I’m using an Aqara H1 EU No-Neutral wall switch, and it works perfectly with a regular (non-smart) LED bulb — but not with my Philips Hue E27 (9 W) bulb.
After about a day, the switch loses power completely (no blue LED, doesn’t respond, and times out in Homey).

I understand that “no-neutral” switches draw a tiny leakage current through the connected load to keep the electronics powered. Some LED drivers block that current, which causes the switch to lose power.

Now that Aqara has released their LED Bulb T2 E27, I’m wondering:
:point_right: Does this bulb allow enough leakage current to keep a no-neutral Aqara switch powered on reliably?

If anyone has tested this specific combination (Aqara H1/H2 No-Neutral + Aqara LED Bulb T2 E27), I’d really appreciate hearing your results — e.g.

  • Does the switch stay powered and responsive over time?
  • Any flickering or glowing when off?
  • Do you still need a bypass capacitor?

Thanks a lot!

(Setup: EU 230 V, single-pole circuit, no neutral available in wall box)

Install an additional bypass in the ceiling junction, then you won’t have to worry about using smart bulbs. For example

Thanks a lot for your reply! :pray:
Yes, adding a bypass like the Shelly one is definitely a solid workaround if it turns out the switch can’t stay powered otherwise.

That said, I’m hoping to avoid adding any extra components in the ceiling if possible — so I’m mainly curious whether the new Aqara LED Bulb T2 E27 already allows enough leakage current on its own to keep the H1/H2 No-Neutral switch powered reliably.

Hello, from my experience, old Aqara smart lamps did not provide enough current for H1 (especially when the brightness is turned down), I screwed an old lamp into one base, from which I removed the filling and soldered a capacitor. So far, everything works.
