is that because I don't have a 1.5 serial gateway ?

Gateway version shouldn't matter if you get this message at startup of node.

what should I do from there ?

I have the socket and the FTDI on the same side so I may avoid the above ?

I don't understand what you mean.

this was related to the electric perturbation with headers close to the radio

@epierre Can you confirm the settings you used in the IDE to program it? Are you sure there are no solder bridges where you soldered the radio or socket for the radio? Have you tried powering it with a couple of AA batteries after you uploaded the sketch?

Today I integrated my first 2 sensebender micros into my homeautomation and they almost worked out of the box. I like this board really much! Good work, I will order more!

Pitfall:
When updating the mysensors lib from 1.4.x to 1.5 the sensor failed to get an id from the controller which btw was still running on 1.4.x.
After having done all the things like "clearing eeprom", "soldering a capacitor to the radio" and so on... I noticed that I changed the RF_CHANNEL from the default 76 to some other value in MyConfig.h some months ago (probably for some paranoia reason).
When updating to lib 1.5 the sensor sketch got the 76 while the gateway still used the other one and so the communication between both failed. After changing the radio channel to the one the controller uses, everything worked very quickly!

Probably this post helps someother guy who fell into the same trap.

Hi,

My sense bender works perfect when sending directly data directly to serial gateway (vera 5), however when I move it out of range to the serial gateway and want it to connect to my repeater node it does not want to discover the repeater node. Anyone else had this problem?

hek

Remember that it takes a few ( ~5) failed transmits until it searches for a new parent node.

@johnr

Is your repeater node still on MySensors 1.4? I had a similar problem and upgrading to 1.5 solved it.

johnr

You are probably right. I did not realise sense bender was pre loaded with 1.5

I think easiest for me would be to downgrade sense bender to 1.4 is it possible?

tbowmo

Sensebender is still on 1.4, as we haven't prepared new firmware for it yet.

Mysensors 1.4 and 1.5 should be compatible with each other, right @hek ?

hek

Yes, it should.

But as @Dewalt says, there was a bug in repeater functionality. So upgrading the repeater is a good tip.

johnr

Upgrading repeater to 1.5 solved this issue. Thanks for the quick help. 1.4 sensors communicate OK with the 1.5 repeater as far as I can see right now.

I try to make a 3D box for SenseBender Micro with CR123 battery.

Nice work, what is the dimensions of the enclosure?

question about the default sketch for this board.
if i read correctly


// How many milli seconds between each measurement
#define MEASURE_INTERVAL 60000

// How many milli seconds should we wait for OTA?
#define OTA_WAIT_PERIOD 300

// FORCE_TRANSMIT_INTERVAL, this number of times of wakeup, the sensor is forced to report all values to the controller
#define FORCE_TRANSMIT_INTERVAL 30 

// When MEASURE_INTERVAL is 60000 and FORCE_TRANSMIT_INTERVAL is 30, we force a transmission every 30 minutes.
// Between the forced transmissions a tranmission will only occur if the measured value differs from the previous measurement

// HUMI_TRANSMIT_THRESHOLD tells how much the humidity should have changed since last time it was transmitted. Likewise with
// TEMP_TRANSMIT_THRESHOLD for temperature threshold.
#define HUMI_TRANSMIT_THRESHOLD 0.5
#define TEMP_TRANSMIT_THRESHOLD 0.5

if temps don't change more than .5 i shouldn't see a transmit but once every 30 minutes
i have 2 running right now
and both send temp and humidity every 1-2 minutes and the numbers are the same or in some cases only different by .1
i have it set to .5 so the question is

why does it transmit every minutes when the temp and humidity are the same
why is it transmitting even with as little as .1 change
1 board is running 1.2 and the other is running the 1.3 sketch from git
Battery however does transmit every 60 minutes as it's supposed to.,
thx

@mvader

Have you tried to hook up a serial connection to your sensebender? It writes the difference from the last transmitted measurement, everytime a new measurement is taken (every minute).

I will make some improvment (can not test, my printer is in maintenance mode !) and post files for others.

so if i want it to transmit less frequently (save battery?) i would increase the measure interval. correct?
I have some situations where i want frequent measuring (1 minute), and some where 15 minutes or 30 minutes would do fine.

tbowmo

@mvader

Yes, you could save battery, by changing to 10/15 minute check interval..

But still, the interesting thing is why it transmits every minute.. That's why I would suggest to check the serial output..

There is an explanation to the problem further up in the thread:

@gloob said:

Hello

I found an error in the sensebender micro sketch in the latest release.

The calculation of the temperature change is wrong.
float diffTemp = abs(lastTemperature - (isMetric ? data.celsiusHundredths : data.fahrenheitHundredths) / 100);
needs to be replaced with
float diffTemp = abs(lastTemperature - (isMetric ? data.celsiusHundredths : data.fahrenheitHundredths) / 100.0);
The division with 100 needs to be 100.0 otherwise the result will be an integer instead of a float value and the difference will be the decimal places of the last temperature.

thanks for helping my memory :)
