Old school reliable full power 240v 13A UK RC sockets.
Sadly no longer in production the identical half dozen remote control 13 amp switches I already own have been working for over a decade - some closer to 20 years- but change room layout (and storage in a conservatory) predictably resulted in a shortfall.
Adding a pair from a 'new old stock' supplier was simplicity itself, and was both a cost effective and more reliable, having outlasted several newer, lower cost but horribly temperamental (and failure prone) Wi-Fi and Android phone alternatives.
