i need help to create a node for a elero shutter system.
This is my first request to the community. I am more a user than a developer.
Hopefully someone can help me.
This is the elero usb transmitter stick.
The shutters will be manually paired to that Stick.
If you connect it to the RPi3 it will react on serial commands, like AA054C000140C4.
There are already guys who implemented this device into Homematic, FHEM,openhab and home-assistence.
Maybe somebody can help me to get this working in node-red
Examples for sending commands.
0xAA … Startbyte
0x05 … Length of Data
0x4C … send command
0x00 … channel bits for Channel 9 to 15 (8 (0x00,channel1-8, 0x01-channel9, 0x02-channel10, 0x04- channel11, 0x08-channel12, 0x10-channel13, 0x20-channel14, 0x40-channel15)
0x01 … channel bits for Channel 1 to 8 (0x00,channel9-15, 0x01-channel1, 0x02-channel2, 0x04-channel3, 0x08-channel4, 0x10-channel5, 0x20-channel6, 0x40-channel7, 0x80-channel8)
0x40 … action (0x20 .. up, 0x44 … intermediate position, 0x24 … tilt/ventilation, 0x40 … down, 0x10 … stop)
0xC4 …Checksum (Sum of all bytes == 0x00)
Example for requesting status
0xAA ... Startbyte
4D ... Read Status
00001 ... Channel 1
01 ... actual Status of channel 1
02 ... checksum
the return will be the satus of the fist shutter.
