Help with HTTP Request to Ezlo hub to get temp

[cw-kid]

I have a temp sensor on my Elzo Plus hub and I wanted to try and send a HTTP Request from MSR to capture that temp data.

I have tested my API HTTP URL in postman and it works in there OK.

I then created a new rules in MSR which I think is correct?

When I run the Action with the Play button I then see this message.

Side Note: We can no longer copy and paste the text from these MSR alerts, since the panel layout changes.

Thanks

Ticking the option Ignore self-signed/invalid SSL certificates seems to have got rid of the error now and there is now data in the local expression.

So now I just need to figure out how to extract the temp value from that data, as I want to send it to a virtual temp sensor on my Vera Plus hub.

@cw-kid is there a reason you are not just taking the value from the Reactor entity?

Very good question and I should of done it that way LOL.

For some reason I just had using their HTTP API in my mind.

OK let me try it that way instead using the Entity.

I am just struggling at the moment trying to create a virtual temperature sensor on my Vera Plus.

Doing this as Home Remote does not support Ezlo hubs and I wanted this temp sensor in my dashboard app, so it has to be a device coming from the Vera Plus hub, but its actually paired to the Ezlo Plus hub as its a Zigbee device etc.

Its a shame Rene's Vera -> Ezlo bridge plugin didn't work both ways Ezlo -> Vera also.

OK I am stuck, I assume I need some expression code? to look at the "Bathroom Temperature" Entity / Device on the Ezlo Plus to extract the current temp value in to the local expression data.

Once I have that I can then have an Action to Set Variable and send that value to the virtual temp sensor on the Vera Plus.

Maybe something like:

getEntity( 'ezlo_plus>device_61f0bbc0123e4312a1900a1b' ).attributes.temperature_sensor.value

EDIT:

That seems to work but its a long number

EDIT2:

Running the rules action it has sent data to the virtual device on Vera

However on the main device view I see no value shown.

Maybe something wrong with my virtual device on the Vera hub or it didn't like to display the long number.

EDIT3:

I was using the wrong service on the Set Variable Action it should of been:

urn:upnp-org:serviceId:TemperatureSensor1

I now see the data on the device in Vera, however I still need to round down the long number in the local expression some how.

Also looks bad in Home Remote:

How about round() https://reactor.toggledbits.com/docs/Expressions-%26-Variables/#arithmetic-functions

Hi Crille

I was just looking in to that

Not sure how to round however so it would show something like 16.5 rather than just 16.

[cw-kid]

Got it:

round(BathroomTemp,1)

So now instead I have to send the value of the expression called "BathroomTempRound" to the virtual device in Vera.

Which works:

[Crille]

@cw-kid Yes, but you don't need to create a new one, just do it like round(getEntity...sensor.value, 1) in your first expression.

[cw-kid]

@crille

Got it, that's even better and working also now.

Thanks

I created a How to Guide on the Vera forum, mainly so I don't forget how to do this and others may find it useful also.

Example MSR rule to bridge back a device from an Ezlo hub to a Vera hub for Home Remote dashboard

I setup this rule today in MSR and a virtual Humidity Sensor on my Vera Plus. I have a real Humidity sensor device (Zigbee) paired to my Ezlo Plus. But as Home Remote dashboard app does not support Ezlo hubs and I wanted a tile showing the Humidity value, the device has to come from the Vera hub...
