MySensors = node --> gateway --> HA Controller
If you want to use ESP8266 it is as easy as: ESP8266 node --> MQTT broker --> HA Controller
The MQTT broker can run on a RPi (mosquitto for example)
Regarding the ID assignment that will be DHCP if you want
Just my 2c
@Grubstake if you build a MQTT MySensors gateway, there's no OpenHab binding needed. Disadvantage is that you need to configure your nodes in OpenHab manually.
@gohan said in N00b + MQTT gw + openHAB2:
but anyway ethernet is the best solution for beginners because you can use myscontroller to debug messages while connected to controller.
With MQTT you can also debug using MQTT-Spy or MQTTLens or various other MQTT apps.
MQTT is easy in interconnecting various systems without they have to know about each-other.
As long as you have a MQTT broker (RabbitMQ, Mosquitto, ActiveMQ, ...) you're all set.
In OpenHab in conf/services create a file called mqtt.cfg, and past the following:
mqtt:broker.url=tcp://ip-address-of-mqttbroker:1883
mqtt:broker.clientId=openhab
mqtt:broker.retain=true
mqtt:broker.async=false
Then in your items file you can do:
Switch Light_GV_Hall "Ceiling" (GV_Hall, Lights) {mqtt=">[broker:myhome/room/switch1:command:ON:1],>[broker:myhome/room/switch1:command:OFF:0],<[broker:myhome/room/switch1:state:ON:1],<[broker:myhome/room/switch1:state:OFF:0"}
And now you can turn on/off the light from OpenHab as wel as from any other device that publishes to the same toppic (yes, even from MQTT-Spy and MQTTLens)
@Boots33 no, it's not the FS1000 type, but a regular cheap RF433 transmitter.
The problem is that when powered with 12V, the transmitter does not see the 5V on the data pin as high.
Hi guys,
who can help choosing a component.
I'm building a RF433Mhz node to control wireless powerplugs. The transmitter works fine at 5V but the range is not that great.
The transmitter can handle up to 12V, but I have no clue what transitor/fet i can use for both the power line and the data line.
Yesterday I tried to use a opto-coupler but that is not fast enough, I clearly see on the scope the signal fading out when going from high to low.
I also have some BC547 laying around, but that is inverting the signal, not what i want.
Anyone can make some suggestions?
Thanks in advance.
Eric
Dunno about that one but I bought a Rigol 1054z 50Mhz which you can freely upgrade to 100Mhz
When running as a service, is there a way to watch the debug log?
