I have been away for a while but it seams quite some of you are experiencing problems, I'll try to take a look at it. If you find any more details, please let me know!
Hi @doctor64 ,
How did you solve the battery reporting?
Did you implement the changes in h and cpp file from the link and compiled/uploaded the gateway sketch again?
Never mind figured it out.
There was a problem somewhere in that sketch. basically started from scratch again. merged the W5100 MQTT client gateway sketch and the relay sketch. then referred to here for serial MQTT syntax.
Hope anyone else thats struggling finds this info useful.
@scurb This looks very interesting and my factor now to save me from having to create my own :-). I have been planning to do the same thing (although maybe on a smaller software scale) by writing a simple Python server that would pull serial packets off of a gateway arduino (either running mysensors or something I write myself) and pipe this through MQTT to openHAB. I have two questions:
How do you interface with a sensor network? Do you go through a serial connection to read the serial packet format (a,b,c,d)? I see several implementations that put the mqtt client directly on the Arduino, but it seems much cheaper for me to just plug it into a USB port to get a virtual serial port instead of investing in a separate ethernet shield
How does an item configurations look like for a switch in openHAB? I'm looking to build a toggle switch which toggles light on or off every time it is activated, and I cannot really understand how to configure the switch to allow this behaviour for an mqtt input.
Feel free to take the second question with me directly since this might not be very interesting to the others in the forum
