In the United States, most individual states do NOT require the low-voltage (less than 90v) devices to use UL listed wall plates. But do your own due-diligence.I test fitted to several “old work” boxes for in-wall use as well as surface mount single-gang boxes (like for PVC raceway).Here is a link to the circuit board used ($5 USD): https://s.click.aliexpress.com/e/_DEzohBn***Let me know if you are using a surface box or work box that doesn't fit, and I can see about adj
