Because I am writing a new firmware for a commercial device (Sonoff Touch) adding parts to the circuit is not an option. But at least you confirmed, that MySensors's sendHeartbeat() function does not work with an gateway device. I hope the devs will have a look at that. ;) In the meantime I will try ...

I am using the sendHeartbeat() funtion with an ESP8266 node. The node has only actuators and no sensors. I need the heart beat to prevent Domoticz from resetting the connection due to data timeout. I have set the data timeout to 1 minute. This way Domoticz reconnects quickly when I restart the node ...

The log you posted has nothing to to with Domoticz. It's all pure MySensors. See https://www.mysensors.org/download/serial_api_15

Are you sure the node is sending data to the gateway? You should check this with the serial monitor. Post the results.

Did you try to delete the node (and devices), restart Domoticz and then add it again?

I think I solved the problem myself. V_LOCK_STATUS is not the right type for a door contact. The correct type is V_TRIPPED. After changing this in the declaration of msg the node behaves normally. Still it seems like a bug to me, that Domoticz used the wrong type for a completely different child ...

As far as I know the node only requests an ID at the very first start and safes it to it's eeprom. You could try to clear the eeprom bei flashing the sketch found in \libraries\MySensors\examples\ClearEepromConfig. This way the node is forced to request a new ID from Domoticz.

This is the Sketch I am using. It is based on the LED dimmer example: #include <MySensor.h> #include <SPI.h> #define LED_PIN 3 // Arduino pin attached to MOSFET Gate pin #define FADE_DELAY 5 // Delay in ms for each percentage fade up/down (10ms = 1s full-range dim) //Buttons, digital in with pullup ...

I have a node which acts as a dimmer and a door lock. Normally the dimmer is working fine. However after the node sends a new status of the lock to Domoticz the switching part of the dimmer stops to work. You can set the dimmer to everything >0 and <100. But 0 and 100 do nothing. After checking the ...
