I’m using Sonoff 4CHPro V3 to control some of my swimming pool equipment. Each channel is a dry contact and I’m using in the Normally Open (NO) configuration. I’m using the Ewelink App on my iPhone. When I turn on a channel from the app the button shows as ON (Blue) only temporarily. Why isn’t the status of the channel mirrored to the app button?
• Depress button 1 for channel 1 in the App.
• Channel closes and passes 5V to pump. As it is supposed to. LED on the Sonoff corresponding to Channel 1 is illuminated.
• Button 1 on app doesn’t stay illuminated ‘blue’ or ‘on’. The button illumination turns to white or off after time (not sure exactly how long). The LED on the Sonoff remains illuminated.
• Channel remains closed, however button indicator in app is turned off and doesn’t match actual status of channel.
Why doesn’t the App button mirror the actual status of the Sonoff channel. Something doesn’t seem correct. Anyone else experience this issue?
