MQTT publish doesn't work

---

For some reason the action “publish MQTT message” I use in many rules, doesnt work any more…
For example this rule:
when marcel is present then publish mqtt message \"1\" on topic \"pimatic20/alarm/status/marcel\"
Used to work.
For an other reason i wanted to use an other broker, so I changed my config.json to use that other broker.
ever since my mqtt rules don’t work anymore.
I changed the config back to what it was before, but it still don’t work.

also normally you get a hint when you fill in the first letter in the Actions field in the “add new rule” page from Pimatic. When I enter a “p” I don’t get the hint “publish mqtt message”.

after this I have tried updating Mosquitto, reinstalling the MQTT plugin, restored the config in its original state, but all that did not help.

someone has an idea what goed wrong here?

in my log i see this:
09:18:21.175 [pimatic] info: Loading plugin: "pimatic-mqtt" (0.9.7) 09:18:23.185 [pimatic] error: Cannot read property 'prototype' of undefined
Could this be a hint?

For MQTT you need a certain version of pimatic, unsure what version. Best is to update to the latest version.
Also you are missing the part on broker xxx in your rule.

@koffienl
Thanks for your reply.
I don’t think the broker part is mandatory in a rule, because I have loads of mqtt rules and never used this.

at the moment i am using pimatic 0.9.35, latest version seems to be 0.9.45. I will try to update, not very keen of doing this. eBusd is running on this instance witch is very hard to set up.

Also I think it’s a bit strange, this it used to work! I only changed the config , but changed it back as soon is I realized it didn’t work.

If it worked with your current version, I would try to test with the broker part. I never got it working without the broker part in a rule.

Tried to ad a broker to my rule, saidly this did not work either.
As I said before, usually in the GUI, when try to fill in an action in the rule, you get a hint. For example when I type a “p” in this field you will get a dropdown menu with all the available actions that start with a “p”. Now the only hint is get is “press”, wheras before i could choose between “press” and “publish mqtt message”.
it looks like Pimatic just don’t reconize the action “publish mqtt message” anymore, and I have no idea how to solve this…

Just found out the plugin is not loaded.
I do think this has something to do with it:

21:16:04.931 [pimatic] info: Loading plugin: "pimatic-mqtt" (0.9.7) 21:16:06.937 [pimatic] error: Cannot read property 'prototype' of undefined

I have tried reinstalling the plugin, but i stil get the error prototype error.

Hey @mr_smith
Why not use the latest version of mqtt plugin (0.9.10)?
And yes, the broker is not required in the rules. Only if you rename a default broker, or you want to send data to another broker.
