11. How many seconds can I set for “inching”?

0.5-3600 seconds, must be a multiple of 0.5.

12. Can the timer be executed after the network is disconnected?

You cannot set the timing for the network disconnection, but as long as the power is continuously connected, the already set timing will continue to be executed.

Note: If the network is disconnected for a long time, the time error of the device will become larger and larger; It also may cause the device to restart.

13. Why is IFTTT sometimes not implemented? (Set device A to open and trigger device B to open)

In order to prevent the micro-link scene and IFTTT from triggering each other into an endless loop, IFTTT will not be triggered when the device is turned on by the scene trigger.

14. Can I flash another firmware into the device?

We don’t recommend it. The warranty will be void immediately.

Troubleshooting

Why the external switch connected with S1&S2 sometimes doesn’t respond?

a. Please shorten the length of the cable. If the total length between S1&S2 is too long, it will effect the accuracy of the MINI signal detection for the external switch because of the ripples. The recommended length is shorter than 5m.

b. Connect a 100nF electrodeless capacitor between S1&S2. It will reduce the interference of surrounding and ripples.

Caution:

1. Be sure the wire connected with S1 or S2 is neither Live nor Neutral.

The MINI turns itself on or off sometimes, how I can solve it?

Find out the trigger source by going to the “Logs” in MINI setting of eWeLink APP.

If the trigger source is from other eWeLink account, the MINI is triggered by the account that you shared with.

If the trigger source is “scene”, please check if there is any smart scene settings or 3rd party application (like IFTTT) bound that triggers for the MINI.

If the trigger source is “device”, please confirm that there is no Live wire or other electromagnetic interference around the wires that S1 and S2 connected with.

Caution:

1. Be sure the wire connected with S1 or S2 is neither Live nor Neutral.

The WiFi signal indicator of the MINI in APP is in weak condition while the other device signal is shown much stronger than MINI, How can I solve the issue?

This issue can be caused by the improperly antenna placement. Please be sure below attention notice items are aware.

The antenna head can not be attached on metal object or conductors, if the mounted box (86/EU/etc Type) is made of metal, you should leave the antenna out of the mounted box.

If the mounted box (86/EU/etc Type) is made of plastic or any other insulators, the antenna is allowed to be attached on the box.

The antenna body wire can not be bended over 90 angles to avoid any damage for the wire which effects the performance of the wireless transmission.

Caution:

1. Do not touch the antenna while the MINI is connected by power supply as the antenna is conductors with electricity
