I'm quite new to all this automation stuff and learning everyday a bit more.
My first encounter with automation was the KAKU system... some wall plugs and a remote controller combined with a wall switch on 433. Quite advanced already
.Soon this was not enough and I found a cheap SmartHome wall plug with server function (wifi+433)for the KAKU devices. Now I was able to control the wall plugs via a browser on any device. I did like to see and control more but this was the limit with these units I had.
Then I found Domoticz and RFlink... super. Set Domoticz up on a Raspberry and I had a nice automated system. I could connect and control all I already had in house and add cheap China sensors (Door switches, temp+ Humidity etc) to expand too.
I found the RFlink receive part to be the best, but was a bit disappointed in the transmit range. The cheapest China transmitter did a better job without any antenna connected. Then again the recive part of the China receivers was very bad, so I relocated the RFlink as this was the best option to cover the existing 433 devices I had already. Till so far I am happy, all works.
Now I like to control a central FAN system, but I have no idea how to proceed..
I have temp+humidity data from the bathroom available in Domoticz.
I need to send a value (depending on the Humidity data) to a receiver node which then controls a digital potentiometer to conrol the speed of the FAN unit.
1. 433 is no option due to the limited transmit range. I did make a setup with an Arduino+ 433 receiver setup as KAKU dimmer which works for receiving values between 0-15, but the transmit range is bad.
2. Can I use a WiFi receiver device based on ESP8266 to receive a value from Domoticz and control the digital pot AD5171?
3. How to send an analogue value from Domoticz via WiFi to a receiver node?
4. I have looked into Easy ESP but have no idea how to proceed for receiving values and control the AD5171. Did set up sensor node which transmits data to Domoticz which works fine, but is not what I need.
Best solution would be an ESP unit which can handle the Wifi part and the AD5171 part, but how to make this?
I like to hear from the more experienced users how they would approach this problem and solve it.
