I picked up some used sensors, and would like to play around with them. I also have a few spare transmitter and reciever devices, so i guess i can use those.
What kind of hardware is best, for a DIY RFLink “on cheap” :-)?

Yep, i just found it too 
Thanks!
I’ve also found this;
So both things are now ordered 
Hi, I use my rflink with MQTT gateway on ESP since 1 year without any problems:
Very good projet, just work!
I have Two rflink one 433,92 Mhz and an other for Somfy RTS 433,42 Mhz.
Hello Seb821 could you please publish an mqtt switch or cover entry from your configuration.yaml i have the issue that the state is not changed when i send to the rflink.
This is my current entry :
- platform: mqtt
name: “Rolluik Woonkamer”
state_topic: “rflink/BrelMotor-7f320b”
command_topic: “rflink/cmd”
payload_open: “10;BrelMotor;7f320b;e1;UP;”
payload_close: “10;BrelMotor;7f320b;e1;DOWN;”
state_open: “UP”
state_closed: “DOWN”
optimistic: false
qos: 0
retain: false
Hi There
Trying to get my HA to send using espRFLinkMQTT
Do you have an example of you switch setup?
I can see HA is receiving the MQTT messages using MQTTLens and subscribed to my mqtt server but I cannot get HA to send anything back
Thanks in advance

Thanks for the reply but just cannot get it to send back to espRFLinkMQTT:
This is in espRFLinkMQTT when using the physical thermostat so RFLink is seeing it and espRFLinkMQTT is seeing it
Switching Off:
Raw Data: 20;F0;X2D;ID=000c74e;SWITCH=00;CMD=ON;RC=00fe;S=01;EXT=Tybox;BAT=OK;
MQTT Topic: rflink/X2D-000c74e
MQTT JSON: {SWITCH:00,CMD:ON,SWITCH00:ON,RC:00fe,S:01,EXT:Tybox,BAT:OK}|
Switching On:
Raw Data: 20;EF;X2D;ID=000c74e;SWITCH=00;CMD=ON;RC=1cfe;S=0c;EXT=Tybox;BAT=OK;
MQTT Topic: rflink/X2D-000c74e
MQTT JSON: {SWITCH:00,CMD:ON,SWITCH00:ON,RC:1cfe,S:0c,EXT:Tybox,BAT:OK}
I then get the following in HA when I listen to rflink/#
Message 3 received on rflink/X2D-000c74e at 19:01:
{“SWITCH”:“00”,“CMD”:“ON”,“SWITCH00”:“ON”,“RC”:1cfe,“S”:0c,“EXT”:Tybox,“BAT”:“OK”}
20;32;X2D;ID=000c74e;SWITCH=00;CMD=ON;RC=1cfe;S=0c;EXT=Tybox;BAT=OK;
Message 2 received on rflink/X2D-000c74e at 19:01:
{“SWITCH”:“00”,“CMD”:“ON”,“SWITCH00”:“ON”,“RC”:00fe,“S”:01,“EXT”:Tybox,“BAT”:“OK”}
20;32;X2D;ID=000c74e;SWITCH=00;CMD=ON;RC=00fe;S=0c;EXT=Tybox;BAT=OK;
So, HA is seeing the MQTT coming into it
The only bits that change when using the physical thermostat is the part after 20; and is totally random and then “RC”:00cfe to “RC”:1cfe and back again which is how I figured which is the on/off above
This is my switch

I can see the message being sent in HA but does not seem to get to espRFLinkMQTT as I get nothing on the Home or Live Data pages
I am sure its to do with the payload but cannot figure it out
Many thanks
You have to replace the 20;32; with 10;
Changed and nothing appears in esoRFLinkMQTT but it does show the change in my MQTT listen 
Seems espRFLinkMQTT is just not listening
to my MQTT commands
