new in Tasmota 15.3.0 and Rainsensor RG-15

[Mark-Muc]

Hello . just a short question.
I've uodated to [Tasmota 15.3.0] and in the Rainsesor RG-15 there#s a new value RG15 Valid
in my case it is 1
I checked all changes and readme's but coundln't fine an explantion for it.
can someone explain me the meaning of this value?
and why I can't see this value in MQTT??
"RG15":{"Active":0.00,"Event":0.00,"Total":0.00,"FlowRate":0.00}

Thx for any answer!

Now: Gemini tells me:

What does "RG15 Valid" mean?
Because the RG-15 uses infrared beams reflected inside a lens to detect raindrops, it is smart enough to know if its readings are reliable.

Valid = 1 (True): The optical path is clear, and the internal infrared signal strength is within the normal range. You can trust the data.

Valid = 0 (False): The sensor is detecting an obstruction or an internal error. The rain data provided at this moment is likely inaccurate and should be ignored by your automation systems.

Gemini also tells me, that this valid value i should see in MQTT message:

{
  "RG15": {
    "Accumulation": 1.25,
    "Valid": 1,
    "Intensity": 0.5
  `}`

but that's not true!!

Have a look to Add timeout handling for RG15

Thank you Norbert.. that expains all to me .. but no flag in MQTT .. so i can handle an error ..

Looks like the current driver logic is that the JSON will only be included in the sensor payload if data is valid. Hence you should be able to infer "not valid" by not seeing the data included.

Of course, AI systems are only making guesses, and will sometimes hallucinate things which "sounds plausible" irrespective of facts.

just for info.. my RG15 tels me .. valid = 1

and my paylod in MQTT looks like this:
"RG15":{"Active":0.00,"Event":0.00,"Total":0.10,"FlowRate":0.00},
so it's seems not to be includet in the JSON

Yeah, if it was included, it would always be 1, hence no information value. As observed, you only get JSON when it was classified as valid.
