OpenHAB and MQTT Gateway: moving to GatewayClient - Issue

[xefil]

Hello to all!

I've used OpenHAB with MQTT Gateway for a while without issues.
Now I would like to use local MQTT (mosquitto) and use the MQTTClientGateway to publish/subscribe to mosquitto the messages.
Manually works all well. I can publish manually commands and and the relays on the remote node starts or stops.
BUT, when I configure OpenHAB, changing the publish address, it creates a loop ON/OFF as soon I try to turn a light on. Seems disco

This is the old binding using MQTT Gateway (not client):

Switch  node20_sw2      "Relay02"  (all,node20)            { mqtt=">[mysensor:MyMQTT/20/2/V_LIGHT:command:ON:1],>[mysensor:MyMQTT/20/2/V_LIGHT:command:OFF:0],<[mysensor:MyMQTT/20/2/V_LIGHT:command:MAP(1on0off.map)]" }

This has worked very well.

Now I'm using this:

Switch  node20_sw2      "Luce Stufa"    (all,node20)            { mqtt=">[mysensor:mygateway1-in/20/2/1/0/2:command:ON:1],>[mysensor:mygateway1-in/20/2/1/0/2:command:OFF:0],<[mysensor:mysensor:mygateway1-in/20/2/1/0/2:command:MAP(1on0off.map)]" }

It happens that OpenHAB sends out the message, and I got a reply message back which is replied i immediatly with an OFF:

What's going on?

Thanks!

I cannot see the incoming traffic in your log.

Could it be the node sends an ack message back (even though you're not asking for it)?

(but it shouldn't send an off command in that case... weird)

I'm not an expert on MQTT, but I think you have a small config problem with where you are publishing and retrieving your data. There should also be a mygateway1-out in your string as well. The out is used for MySensors to communicate with the home-controller.

Hello!

I've converted the entry from:

Switch  node20_sw2      "Luce Stufa"    (all,node20)            { mqtt=">[mysensor:mygateway1-in/20/2/1/0/2:command:ON:1],>[mysensor:mygateway1-in/20/2/1/0/2:command:OFF:0],<[mysensor:mysensor:mygateway1-in/20/2/1/0/2:command:MAP(1on0off.map)]" }

to:

Switch  node20_sw2      "Luce Stufa"    (all,node20)            { mqtt=">[mysensor:mygateway1-in/20/2/1/0/2:command:ON:1],>[mysensor:mygateway1-in/20/2/1/0/2:command:OFF:0]" }

And now works.
BTW I need to understood better why, removing the last part, it works. Does this query the status? In this case, then the solution could be right as written by you @drock1985 . Maybe in that case I should ask with mygateway1-out.

Oh, maybe that's exactly the case:

https://github.com/openhab/openhab/wiki/MQTT-Binding#item-binding-configuration-for-inbound-messages

It writes:

direction: This is always "<" for inbound messages.

So, having those 3 arguments in the original version:

1. ">[mysensor:mygateway1-in/20/2/1/0/2:command:ON:1]"
2. ">[mysensor:mygateway1-in/20/2/1/0/2:command:OFF:0]"
3. "<[mysensor:mygateway1-in/20/2/1/0/2:command:MAP(1on0off.map)]" "

I think it means:

1. outbount to turn ON
2. outbount to turn OFF
3. INBOUND to check

So, I need to change 'mygateway1-in' to 'mygateway1-out'. This would explain why I was going in loop.

I THINK AT LEAST.

I'll give a try this evening.
