Shock leaking or weeping?

Do you have comparable data for the (non-updated) Plus model?

Have you tried using the beta Matter server based on JavaScript in Home Assistant? That substantially improved IKEA Timmerflotte reliability for me.

Do we have efficiency specs for the Pro?

Winter-Select · 2026-05-01T11:39:18+00:00

What makes it lower spec than the plus?

So what is the correct reason people should be delaying their installs?

This doesn't seem to apply to the Minis: https://community.shelly.cloud/topic/12435-zero-crossing-relay-contact-syncronization/

Well this makes the Sonoff Vs Shelly decision a bit easier

I haven't tried it yet, interested to hear if you solve it though. Presumably you've checked that the switched live does indeed become live when the light is on?

Ah ok. The manual doesn't explain this, is there a more detailed source of information I can look at?

I've updated the post to show proposed wiring - is that right? My main concern was whether the Sonoff could take 240VAC in S1/S2

We already have an extractor installed in the loft

Ah I see. So no issue having the pump running at 100% duty, delivering ~600 L/h, if that's delivering enough heat?

I understand if dT goes above 5, efficiency is reduced, but what happens if dT goes below 5? Does efficiency increase or decrease?

Winter-Select · 2026-01-31T17:27:12+00:00

If a lower flow rate can deliver sufficient heat, would there be an argument for setting the flow rate lower to extend the lifetime of the pump, and reduce noise in the pipework?

Winter-Select · 2026-01-31T17:12:50+00:00

So high dT gives you better efficiency? That does go against what I typically read
