I apologize for writing in English.
1) the control remains the same, the ESP8266 is only activated for a few seconds after the sensor status change or if reset is pressed.
2) You can leave Link 2 blank "or use an invalid Link" but the module will start for a few seconds.
3) NO. It cannot be added to the Supla server, this module works with batteries and is normally disconnected so it cannot communicate with the cloud.
it only sends Direct Links when the sensor state changes.
You can only see its effect when I send Direct Link.
4) yes. you can activate by bridging the sensor contacts.
The Direct Link can be a notification to Telegram using a bot.
the photo is just for reference to show the connections.
only 1 file is uploaded
To upload the software, in the download there is an image and that is worth a thousand words.
