Bathroom lighting setup

Configuration Zigbee

Hi all

We are having our bathrooms done, and we are having only LED strips with these controllers:

We also have regular, dumb Click ‘Deco’ light switches.
All the other rooms have normal light bulbs, and Sonoff no neutral units, so we can turn the light on and off using switch, and HA: https://www.amazon.co.uk/dp/B0B74H2P6G?ref=nb_sb_ss_w_as-reorder_k4_1_6&amp=&crid=2HJWHPEYAJL5Z&amp=&sprefix=sonoff

However, this won’t quite work in the bathroom. Ideally, I think the LED strip controllers would be permanently powered, and the dumb light switch would just send a zigbee signal to turn the strip on and off via HA. However, how can I do this?
The sonoff unit won’t do this, as it needs a light fitted to it as well as the switch. This wouldn’t have a light, just a switch

What you are looking for is a Zigbee relay with decoupled mode. There is an extensive discussion about the latter HERE.
