ESP8266 CC1101 to control ITHO ecofan RFT [WORKING!]

Post by najtram » Monday 05 February 2018 19:06

I managed to get a ITHO ecofan RFT being controlled by domoticz. I used the code from klusjesman (see link below) and used the default humidity code from domoticz wiki.

I used a ESP8266/nodeMCU and a CC1101, and a humidity sensor of Cresta.
This message is just to inform people that this is a working solution.


Klusjesman code from: https://gathering.tweakers.net/forum/li ... /1690945/3

Domoticz on Raspberry Pi 3 with USB RFLink Gateway at 433 Mhz for several KAKU switches. Bluetooth Soma Smart Shades. USB Opentherm Gateway connected to Remeha iSense with Remeha Tzerra boiler. ITHO ecofan RFT (ESP8266+CC1101). Almost running homebridge.

I followed that thread a long time. and I saw that a user Jodur made a compiled version
https://github.com/jodur/ESPEASY_Plugin_ITHO

The only thing I have to do now is soldering and I gonna test it.

Interesting code, because it looks like it has a bit more options than I do.

For sake of completeness here's what I did:

bought:
NODEMCU: https://www.elektor.nl/nodemcu-microcon ... 66-and-lua
CC1101: https://www.ebay.com/itm/381475961886
Sensor: https://www.weerstationkopen.nl/accesso ... kan-sensor (for RF-Link 433mhz connection)

Soldered as described here: https://github.com/supersjimmie/IthoEcoFanRFT

Used Arduino IDE to upload code from klusjesman: https://gathering.tweakers.net/forum/li ... /1690945/3
Tested with http://ip/timer etc (see code)

Then I used domoticz as below:

Used this script for activating on humidity: http://www.domoticz.com/wiki/Humidity_control

I ended up with two switches:
1 Virtual switch is being activated by humidity control script of wiki
2 Virtual switch which is being activated by blockly if (1) is on.
- 2a has a http command wich is send to esp8266 wich activates the timer each time it set to on.
- 2b has a timeout of 5 minutes (no action just switches the virtual switch off) after off, it wil check state of 1 again and stay off or just restarts the timer command.

So result of 2 is it wil activate the timer command each 5 minutes as long as virtual switch 1 is on. When 1 is off, it will finish the timmer of 10min and then stop.
