Sorry to bump this all thread back to 2018, but I have a question.
Is it already possible to use MySensors and this all in one P1 domoticz sensor? (usage1,2 / return1,2)
The examples I can find create 2-4 new sensors in Domoticz. I'm looking forward to the possibilitie if it can be done with one 
It can be done with a P1 http request but as a MySenors user I want to do it with mysensors.
The idea is to use this PCB as P1 and Watermeter
@tbowmo interesting indeed, tnx for sharing. Currently I still use Domoticz for the API Logging is done with INFLUX and Grafana. However in addition to Domoticz I use Pass2PHP. I can now control everything with PHP. PHP seems pretty common so a lot of examples I can find online ;-0. I am a complete MQTT / NODE-RED NOOB.
@marsault6 If you are going to use an ESP8266 (like nodeMCU) you can configure it as an actual mysensors gateway + Node. The Node would be your watermeter.
I received my unit today. Let's see if we can make the baby talk MySensors.
Finally, the last day of my holiday I managed to upload the Mysensors Sketch into the NodeMCU to control my 900 LEDS. It will also read the lux intensity in the livingroom. So if it is dark the lights will switch on.
All is based on @Yveaux Mysensors ESP Gateway port. On a rainy saterday last year @Yveaux and I found out we did not have to modify anything on the voltag level for driving the LEDS.
The sketch includes all the Doll_House animations (around 55) that can be skipped through using an old 433mhz remote (or via interface directly ofcourse) Next stop... Installing 15 meters of LED in the livingroom. pffff
And putting everything inside this little box @Yveaux printed for me.
@kimot said in Combining MySensors examples:
MockMySensors
Haha tnx glad I learned something today. Did not know about this example
@bluezr1 I can imagine your struggle. Have had my fair share as well. The following code is running stable and has around 9 sensors it is serving. Maybe you can grab the pieces you need for your nodes. Unfortunately did not make a video.
Just an update regarding the Renovent Climate system:
I created the following cheat sheet:
To be able to read the 'filter' value I converted the default RJ11 to RJ12.
Now it should be able to warn me that I need to change the filter.
As I use the EasyPCB and already used all available pins on the prototype board, I had to solder an extra wire to pin 8.
Q: How do I access A2, A3 and D8? A: They are not accesses through the PCB, so you need to directly solder to the pro mini.
As this Pin 8 is not used with pull up resistor (I thought it was dangerous to do that because adding 3v of the Renovent would kill the input.) I needed to build some sort of pull-down resistor from keeping the input pin from floating. And hell yes it was floating like hell (resulting in a lot of messages, that even the debouncer was unable to deal with).
Normally when the filter is 'clean' there is a 0v on P8. If the filter needs to be cleaned there is a +/- 3v on P8
This how it was solved:
I found out that the brinks solution I build some time ago could be upgraded with a nice additional feature. 'Filter detection'.
I created a cheat sheet as my device was equiped with RJ11 connector and 3 wires. I needed to convert it to RJ12 with filter detection.
A nice black conversion box Output wires are the same colour as the original RJ 1 wire. With 2 extra wires 3,3v or 5v for the digital 'one' on the arduino.
