Troubleshooting

I think it's also worth to note that the swing will increase significant near the battery end of life. At least from what I've seen.

It is relatively easy to send a command to an existing node (you can do this via serial monitor and a gateway node or even with any other mysensors node). But you did not write the setup of your system. Who will send the command (the fhem gw node)? which node will receive (another node especially for controlling the relais)? I did not get who shall do what with which ressources..

@Hausner So the problem is with the node transmitting anything to the gateway? Post the radio messages from the serial monitor and hopefully someone can tell you what's going on..

@Baran Your sensors is requesting an id from the controller http://www.mysensors.org/download/serial_api_14

@Dominik-Paľo Hm, it seems that there is problem in Windows 10 TP > http://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_devices/windows-10-serial-usb-problems/438de66f-7294-4c06-b4fb-89b45d005ca0?tab=question&status=AllReplies&status=AllReplies%2CAllReplies

I didn't think the voltage drop would make enough of a difference to notice, but i guess it does. I might have to research and look for a more efficient Mosfet.

Turned out that the Nano was faulty. I rebuilded the setup with a new Nano, and it's now working as designed :)

@pvoj It shoud work. It works for me and other users also reports it works.

@gadu String totalProjectSuccess = itWorks + wifeIsHappy; :)

@hek: Success! Now recieving temp and humidity readings on my Android tablet MQTT app (MyMQTT). Thank you very much for your expert advice.

@Rek What do you have right now?

Thank you @Jackpot Don´t Works for mi. As somebody told, I think is the MQTT Gateway that no respond to requestTime. I`m not software men but I think the sketch is correct and MQTT Gateway should answer wirt the value in "receiveTime"

@brettzky84 my congratulations) YAW

You should not typ "\n"! It means that you should press enter on your keyboard. On Linux I saw that I have to send "\r\n" instead of "\n". "\r\n" (Carriage return, Line feed) is the Windows return, "\n" only the Linux return.

SOLVED I found that the older library I was using for the initial code returned a boolean for the read indicating whether or not data was still available in the register. In the newer mysensors library, I could change to use done = !radio.isAckPayloadAvailable(); and everything is now working.

@Mattia-Reggiani Good to see that you solved it and learned by doing. Congrats! Boozz

@olaeke yes the softspi is enable. If upload from the pc the radio work

I use a cheap Chinese 5100 module together with the MQTT gateway and it is warm but have not measured any actual temperature. Works 24 hours a day (now for a couple of months). Most problems have been due to the MQTT code implementation itself . But for most "simple" sensors it runs OK with Openhab.
