The itho version can be fount here: https://github.com/incmve/ESPHome-Itho
Cloned from https://github.com/supersjimmie/IthoEcoFanRFT
I used A CC1101 module, might work with others like CC1150.
Connections between the CC1101 and the ESP8266:
CC11xx pins ESP pins Description
* 1 - VCC VCC 3v3
* 2 - GND GND Ground
* 3 - MOSI 13=D7 Data input to CC11xx
* 4 - SCK 14=D5 Clock pin
* 5 - MISO/GDO1 12=D6 Data output from CC11xx / serial clock from CC11xx
* 6 - GDO2 ? Programmable output
* 7 - GDO0 ? Programmable output
* 8 - CSN 15=D8 Chip select / (SPI_SS)
Beware that the CC11xx modules are 3.3V (3.6V max) on all pins! This won't be a problem with an ESP8266, but for Arduino you either need to use a 3.3V Arduino or use levelshifters and a separate 3.3V power source.
For SPI, pins 12-15 ()aka D5-D8) are used, a larger ESP8266 model like (but not only) the ESP-03, ESP-07, ESP-12(D, E) or a NodeMCU board is required.
Added a web interface and simple API to control it from something like https://pimatic.org/
Also able to give commands by USB
API work like this:
http://192.168.x.x/api?action=Low
http://192.168.x.x/api?action=Medium
http://192.168.x.x/api?action=High
http://192.168.x.x/api?action=Timer
http://192.168.x.x/api?action=Learn
http://192.168.x.x/api?action=reset&value=true
OTA updates work with .bin files!
I am not a programmer!! Use at your own RISK!!
