I've been able to get MySensors working with HomeGenie using the MQTT gateway. It doesn't have two-way communication or software-based pairing yet, but I'll work on those in the future.
Just one final question... is the approach to MQTT correct or should I stick with simple Ethernet? I was planning on using OpenHab or Home Assistant.
Thank You all
@micah said in Can't get OpenHAB2 to see my MQTT messages:
I'm still not sure if the second and third line in the mqtt-eventbus.cfg is correct. I don't have MyMQTT anywhere else, so I think I may try different combinations to see what works.
MyMQTT should be replaced with brokername (mysensors in this example). openhab will then publish the event to the mqtt broker on its topics (useful if you use f.eks. node-red for openhab rules)
@Eric-Buhring great to hear that you managed to get it working. I have used solution like this (arduino+eth. shield+rf24) for some time.
Now I have switched to esp8266+rf24(version with antenna) as a gateway, it is a cool (and smaller) solution
@celonunes generally raspberry pi with serial usb but also you can see some mqtt logs. Same problem with mac os with serial usb.
I also tried rpi uart pins for serial bu there is no logs for it.
Maybe someone gives his Openhab dir i can understand better problem isnt related with hardware
Qu3Uk,
I did get a chance to test with a Fitbit recently. It technically worked, but not all that well. The thing is, the Fitbit only advertises every 2 seconds so latency is a bit high. But worse, its apps really want to be connected to it often to sync; and whenever it's connected, it stops advertising and the detector then can't pick it up.
TommySharp,
At this point I don't plan to modify the board much but having it read environmental sensors would be a cool feature!
For that, would be nice to make little beacons that read sensors and advertise/broadcast the readings every few seconds. Then they could be very low-power, run on coin-cells for months, and could be placed anywhere instead of needing it to be hooked up to USB power like the main board is. Like these: https://sen.se/peanuts/ I'm curious if it could read them.
As for enclosures, I know. I would love to have some nice ones but at this point I'm making too many boards to 3D print enclosures, but too few to afford injection-molding tooling to make a custom case.
Although it should not be too difficult to make the MQTT Gateway with WiFi work on hardware and software level it is a bad idea on system level:
WiFi and MySensensor NRF24L01+ use the same 2.4 GHz band and with the antennas close a transmit from one will block the other and vice-versa.
@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
