Porting MySensors to work with the RadioHead library
-
I'm still having some problems with the sensors being a bit unreliable. For instance, I have a Power sensor that detects LED blinks off my power meter and switches its own LED at every blink so that I can actually see if anything is happening. This works fine for several days, and power usage reports are sent to the gateway at regular intervals (two minutes), but then suddenly the power reports stop. The LED keeps blinking, indicating that the sketch is actually doing what it is supposed to, but for some reason the radio stops doing anything.
I have also had this happen on the gateway, the radio stopped responding after some time even though the sketch seems to be running. This is both on the moteino and anarduino with the RF 69 radios.
I have no idea what is causing this, but my best guess is that some kind of buffer is overrun, or maybe a counter?
Not really sure how to debug a problem like this, but I think the first attempt will be to try to reinitialise the radio after a specific amount of time to see if this clears the problem. The time before the issues occur can vary from 10 hours to 5 days, though, so it is a bit difficult to test...

@kolaf, how are you powering the radio? Cheap phone chargers usually introduce noise into the power line, which drives the radio crazy. A capacitor between radio VCC / GND help in some circumstances: :
-
The radio is integrated into the Arduino board, so it is difficult for me to do anything with the radio VCC line. Anyway, the gateway is powered directly by the computer, home of the power sensor is powered by a Samsung charger which should be relatively good quality?

@kolaf I run the same setup now for more than a 2 month and don't have this issue. For now I am running the power sensor of battery as my meter is outside my house as there is no 220 plug to run it off power supply. I still have a very small RF69 sensor network. I have 10 NRF24 sensor that I am now converting to RF69. Can this issue that you experience be to the size of your sensor network?
Here is some data from my power sensor for this week:

Thanks for the suggestions, and for the proof that can actually work long-term :-).
I have now replaced the 220 V adapter with another one, so let's see how it goes now.
@Francois: I assume youre figures are from domoticz or something similar? How do you like it? I have used openhab for quite some time before I tried to switch to domoticz for a few months. I found that adding new sensors and displaying data was much easier in domoitcz, but the rule and persistence system of openhab is much better, as much so as to outweigh the benefits of domoticz. I switched back to Openhab a few weeks ago.
BTW, you don't want to see my power Usage numbers, they average around 5000W with a peak at nearly 15 kilowatts, Depending on what is running. This covers a full farm with two houses, a big barn, and some other stuff, but still...

I'm also using the serial Gateway via a mqtt perl script to send recorded values to the broker, and then a is the mqtt binding in openhab to communicate with the sensor network.
Yes, we have a three phase power, into the building, as was going out to both the bon and the secondary house. I've been looking into getting one of these clamp power meters, but I'm not sure if these can deal with a three-phase power. I would very much like to be able to measure the amount of power that is consumed by the secondary house so that I can get an exact amount he should pay for the electricity bill :-).
Do you have any experience with using clamp power meters on three-phase power?

Hello folks.
There is any plan to include into mysensors the LoRa RFM95 ,96? I am currently testing one those modules at 433mhz with RadioHead library. I had conducted some test in suburban environment and getting around 1.8 miles range. I pretend to apply this for remote water pump control monitoring in farms. I still want to try the rfm69 and see how much range I can cover . Any advice will be highly appreciated.
Regards
