To enter or change the settings:
To enter the WiFi configuration mode, press and hold the button for at least 5 seconds.
When in Wi-Fi configuration mode, the device enters Wi-Fi access point mode and the status LED turns on.
- Log in to https://cloud.supla.org (registration is free) and Activate registration for new device.
- Connect to the WiFi called "Supla_16X" from any device with wireless network and an Internet browser.
- Open the Page: http://192.168.4.1
- Tap Configure WiFi.
- On the configuration page
- Select the Wi-Fi network at the top by pressing the appropriate one and then enter the password.
- enter the data to:
suplaServer (svrX.supla.org),
Email (registration email in supla),
Supla Device Name (name with which it will be seen in the cloud),
- To finish click on Save to save the configuration data.

Firmware update through the OTA web browser - http: // XX: 81 / update
xx = Device IP. For example http://192.168.1.22:81/update

Supla 16 x 16

added automatic delay memory for monostable channel from local push buttons.
at the moment that one of the channels is configured in the cloud as monostable (staircase timer, garage opening, etc.)
In the first activation from the App the module store the delay that has been set in the cloud.
from that moment the local button corresponding to that channel will act with the same delay.
for example:
In the Supla cloud we set channel 0 as a staircase timer with a time of 60 seconds.
Then we activate that channel once from the SuplaApp (or Supla cloud).
This saves the 60 second delay for channel 0 in the module.
if we press local button 0, channel 0 is activated for 60 seconds.

edited:
Fixed bug to return channel to delay 0 (normal operation) after having been staircase timer, garage opening, etc.
