Relay not reacting first 3 seconds

[derksuh]

Hello all,

I have the following sketch working with a pimatic installation. When i switch on the relay nothing happens
when i keep switching it on and off than after 2 or 3 times it starts reacting. But every time i wait a couple of seconds
i have to switch it on and off a couple of times before it reacts. This is th epimatic log output if i switch it on the first time.

if it starts reacting i get this output.

@derksuh Could you check, if your GW is rebooting all the time?
The debug message

19:45:45debug [pimatic-mysensors]: <- I_LOG_MESSAGE  0;255;3;0;9;MCO:BGN:INIT GW,CP=RNNGA--,VER=2.1.1

looks like a reboot to me.
Root cause could be a faulty AVR board definition (should be latest (1.6.18+) or <=1.6.11). Affected: Serial GWs and Ethernet-GW's.

@rejoe2 said in Relay not reacting first 3 seconds:

AVR board definition

If this is the problem then could i do something about it?

[rejoe2]

@derksuh For information which version of the board defs you use (and for up- and downgrading also): Within the Arduino IDE you can just use the boardmanager (Tools menue, as far as I remember) to do this...
