Hi there. I bought one to run a device from an app. The device can use more than 10 amps so I installed a 16A 230V AC standard relay between the wifi relay and the device. The problem sometimes is if I turn off the app from the relay the normal relay will release then tighten again. Has anyone done anything like this and experienced it? The wifi relay itself works well.
If the normal relay switches off because you turn the wifi relay off, and the normal relay switches back on while you did not send a ‘turn on’ command to your wifi relay, then your wifi relay is bad
OR there’s something wrong with the wiring.
