Customer Review

Hi Guys,
have ordered the relay to operate a door opener via WLAN.
Everything works beautifully. Relay operates makes and does. Only when the Raspberry restarts or crashes, the relay
is permanently on, and the circuit is closed to the Pi rebooted. Is that on the relay, or a GPIO of attitude?

Mfg
