Node with Relay

derksuh last edited by

Hello all,

I have a node to wher a dht22 is connected and a relais, this is to sitch on or off my fan in the bathroom. Before openhab i was using pimatic and that was working good i could see the temperature and humidity and i could turn on and off the relais. No with openhab i get the temperature and the humidity in the inbox but not the relay. Is it somehow possible to get this working?

Greetings, Martijn

To add another option to this thread. I have not yet used them but I am collecting these. They look like they are made for these types of sensors

@ben999 Check out Serial Protocol I have four Arduinos. Each has a different MY_NODE_IDs (I use 130, 131, 132, 133). Each has four sensors: moisture, humidity, temperature, and voltage each of which has a CHILD_ID: CHILD_ID_MOISTURE is 0 , CHILD_ID_HUMIDITY is 1, CHILD_ID_TEMPERATURE is 2, CHILD_ID_VOLTAGE is 3. When an Arduino makes a measurement, it sends that measurement to a unique MQTT topic. In the case of the Arduino with MY_NODE_ID of 130 that is sending the moisture measurement, that MQTT topic is mysensors_out/130/0/1/0/35 and the message is [something like] 760 (35 is the value type) Similarly, when a controller sends a command to a device (Arduino), the topic is unique. If you have two actuators with the same MY_NODE_ID and CHILD_ID (MQTT topic) there would be confusion as to what you want each actuator to do. Likewise, if two sensors had the same MQTT topic, how would the controller know how to handle the data.

Hi @CyborgAndy many thanks for providing the binding update for MySensors 4.0.4! I upgrade my OpenHAB 3.4.4 a few minutes ago to 4.0.4 successfully with your binding update. I use a USB connected serial-gateway. The OpenHAB manual installation upgrade works perfect. I need to do afterwards the following steps in the Karaf console, to get the gateway online again, after the update: feature:install openhab-transport-serial feature:install openhab-core-io-transport-mqtt feature:install openhab-core-io-transport-serial-javacomm Many thanks again! kerberos

Hi @adds666 I did in between the switch from 2.5.12 to 3.4.4 a change from pure textual configuration in 2.5.12 to a UI configuration in 3.4.4. This requires some homework. Can't remember beside the exchanged mysensors binding files anything else to upgrade to 4.0.4 from 3.4.4 and finally to current 4.1.1. Keep in mind, I use a OpenHAB manual installation on a non-Debian Linux system, not openHABian. This may have an influence, but I don't expect any hiccups. kerberos

@ncollins Great! Seem the problem is the delay. With 1 ms or 100 ms I have double message, but with 200 ms I only one message. Thanks a lot.

@TimO No Sweat, found it - it was because the node was powered on before the gateway and presentation didn't go well...
