[Reactor] Assignment to alarm ignored -- expression-driven global cannot be set by assignment

[LibraSun]

It's moments like this that I'm grateful for online Forums where the open exchange of ideas and experience works to everyone's advantage, without fear of reprisal from those "in charge".

Just testing some different online API's see what's possible.

If your in the UK the National Grid have a Carbon Intensity online API here. This is for my region / area.

The data also breaks down by percent the types of generation used, Wind, Solar, Nuclear, Coal etc but not added that as yet.

Vera:

Home Remote:

Need to play about with the tiles and add an icon and reposition some items yet.

[cw-kid]

I've tried the Vera Multi-String plugin, it looks just like the type of plugin I was needing and looking for.

You can have up to five variables on a device.

You can then have your rule in MSR send the data to each variable etc.

The Multi-String plugin devices data is also outputted in the Vera SDATA stream so these device will also work with the Home Remote dashboard app.

{ "name": "Covid-19 Stats", "altid": "", "id": 133, "category": 0, "subcategory": -1, "room": 0, "parent": 0, "variablename1": "Confirmed", "variable1": "4329180", "variablename2": "Recovered", "variable2": "3787312", "variablename3": "Critical", "variable3": "615", "variablename4": "Deaths", "variable4": "126573", "variablename5": "", "variable5": "", "options": "", "configured": "0" },

So I recommend using the Multi-String plugin rather than trying to create your own modified Generic IO devices as I was doing.

@cw-kid if one wanted to set all 5 parameter values at the same time, using an HTTP call to Vera, could that be done? (If so, I'd need to see a working example of a GET Request that does this.) Or would I have to issue 5 distinct calls to set those variables?

P.S. I see from this old post that I'm not the first one to wonder.

It’s so trivial to make a custom request handler in Luup... really it’s one of its best feature. So, in this case, indeed, “roll your own” and simply set the required variables per the content of the request.

@librasun

I am doing a different http request to Vera to set each variable not one request that set them all.

Yeah, something tells me setting more than one at a time isn't possible, anyway. Just thought I'd ask the pros. Thanks!

@librasun Reviving this a bit because this right here is where I think I'm failing spectacularly.

I'm working with the Ambient API for my weather station via Site Sensor in Vera. This thread has been fantastic at guiding me toward migrating the Site Sensor into MSR. Here's where I'm falling down:

The GET returns expected results. However, I believe I've messed up in creating the expressions for temp, wind speed, wind gust, and solar radiation.

I've entered response[1].lastData.tempf into the ambient_temp field and it returns Last value:(error) Invalid reference to member 1 of null. This is taken right from the Site Sensor recipe where it's working wonderfully so I know I'm probably close. I know the expression logic in MSR is slightly different than that of the Vera Reactor plugin - combined with my almost total befuddlement of proper expressions go isn't helping

Appreciate any guidance!

[Elcid]

should that be response[0].lastData.tempinf

[gwp1]

I thought the same but, after editing, it returned the same error just with ...member 0 of null instead.

[gwp1]

@elcid For full transparency, here's how the ruleset is configured (and it's pulling in expected results:

It's only the latter half that's making me stumble.

[Elcid]

so to set temp expression should be ambient_api[0].lastData.tempinf

@elcid Whadya know, that did the trick. Interesting to a noob like me how the original Site Sensor in Vera uses response[1].lastData.tempif and that works just fine.

@toggledbits QQ on the OWM built-in: is there a means by which to render it inactive until I need to call it? The way I work my Site Sensors is the one for OWM stays deactivated until the one for Ambient throws null at which point the OWM turns on, carrying the load until Ambient throws real data back out there again (at which time OWM shuts back off.)

This saves wasted calls to the API for OWM.

[tunnus]

@gwp1 Put a constraint for the OWM rule, something like "ambient == null"?

[Elcid]

@gwp1 vera uses lua, which arrays count from 1
MSR uses javascript which counts from 0

[gwp1]

@tunnus That would work if I were creating the OWM like I've created the Ambient expressions and ruleset. But @toggledbits has OWM built-in, controlled by reactor.yaml config file. The frequency of calls to the API is configured there in minutes and it creates an entity in the Entities list. As I understand it, the entity is always refreshed data-wise by the frequency of the calls set in reactor.yaml.

No. Controllers can only be switched on and off via configuration.
