Very similar to this thread here: Red Series Dimmer -- Light Not As Bright? I have 3 Blue 2-1 switches. They are set up as: non-neutral single pole, dumb bulb mode dimmer mode controlling arrays of ~8 x 12w LED can lights Home Assistant Z2M config Brightness set to 254 maximumLevel set to 254 M…

I’m on 2.08 via Z2M as well. It’s REALLY hard to capture the difference on camera (I need to get a neutral filter), but for me, the difference is being able to stare directly into the bulb in perpetuity on the Blue, whereas it hurts my eyes and I have to look away within half a second using the dum…

Yes, it appears so. Just says, “power output issue for non-neutral at max value”. The more I thought about this, the more I think it did fix the dim level on one of my setups. That’s the problem with having a smart home but also using it as a beta testing house… I can’t remember what switch is on w…

@Eric_Inovelli Thank you for all the prompt attention. This is why I go with you guys.

Yeah no problem, let’s hope we can get to the bottom of this! Ping me here if you don’t hear back in a few days. I don’t mean to forget, I just get side tracked easily!

I think the LEDs are little too bright for the exposed luxmeter, but if I can find an ND filter, this might be a good way to measure the brightness. I also have a bunch of home assistant integrated luminance sensors that could also do the job, again if I can get some smoked glass.

@Eric_Inovelli , @SandyB and others, I’m back with some hard data and a somewhat startling discovery. tl;dr: The brightness drop is associated with a non-neutral setup, and it’s pretty significant. I used an ESPHome illumination sensor connected to a battery power bank to measure room lux. And I ins…

Thank you – very helpful. I’ve passed this onto the engineers as well. I wonder what that reading would be if a bypass was installed. I’m happy to send you one to test.

Happy to take a bypass and give it a shot. Let me know what I can do! In the meantime, I’ve confirmed with another of my Blues - I had originally set it up without a neutral, but there was a neutral in the switchbox. So I took some lux measurements without the neutral, and then connected the neutra…

@Eric_Inovelli any news on the firmware?

Blue switch - not as bright when fully lit?
