Sonoff AL010 adapteri plugi RJ9-antureille – audio-/puhelinplugi RJ9-liitäntään

Older environmental sensors with 2.5 mm jacks often become useless when you upgrade to newer Sonoff Wi-Fi relays that only offer RJ9 ports. The Sonoff AL010 adapter bridges this gap, letting you keep trusted sensors in service without rewiring or buying replacements.
