Hello! I had checked with Terncy and they mentioned that the permanent on feature is being released just a while ago for the neutral switches and will roll out to the non-neutral one via a software update in the Terncy app in the next 3 days. The feature was rolled back in the non-neutral one because of a bug with low wattage bulbs and its being fixed and tested so it will be available very soon. If they message me that they update d ill drop you a PM. So sorry for my unclear instructions. The options should be available in the Terncy app without any physical interaction with the switch when the update is rolled out.

My G2H need wait 6/15... You bought on JD?
Can. It can be switched off via the settings in the app!

The LED indicator act as an indicator haha like it blinks green when it’s waiting to pair, blink yellow when it loses its connection, and also to let you know there is power when you install the switch. I leave it on I find the light ok, not very distracting as I thought it would be.

Yes I did use a non neutral one for testing for a couple months and it worked without issues. So far no issues with wall switches. The neutral ones I also used for 6 months+ d. I had one motion sensor that failed a couple days after I used it but they promptly swapped it out for me and had been working well since then.
You bought from Taobao or Shopee? I think you got a lemon and can ask them to swap one out for you.

I think you are facing this issue. You should be able to get this resolved

I’ve been outstation for some time already and I believe that currently Terncy does not support Homebridge but they’re rolling out support for Home Assistant soon. Maybe it’s possible after that? Currently I’m using them to control my living room lights only.

I joined their wechat group for customers and asked their engineer personally. HomeAssistant support is on the roadmap.

Recently someone had finally made it work even without support from the developer
