I have some code that uses webhooks to retrieve the current weather conditions, sunrise and sunset times, and the 4-day forecast as shown in the screenshot below: [image] I have heard that using String’s is a bad idea when it comes to the stability of the Microcontroller. Can you guys look at th…

@rickkas7 I got it working now! Thanks for your help. I have merged your webhook parsing code with my code that only processes the incoming webhook if the device ID matches the ID of the Photon it’s being received by. This way I have one weather webhook that will work for multiple products. I al…

I’m pulling data from Weather Underground and it looks like it can return data in XML or JSON format. [image] So I will try to use your tools to replicate this weather data feature without the use of Strings and see how it goes. I’m guessing you would recommend that using all the String variable…

The way I’d do it is keep the only copy of the data in JsonParserGeneratorRK. The JsonParser object will store the data and keep an index of it to efficiently extract the data. Then instead of making a copy of every bit of information you want into a separate String, you just request the item you w…

Thanks for the clarification. [image] rickkas7: Then instead of making a copy of every bit of information you want into a separate String, you just request the item you want to use when you need it. That sounds a lot cleaner to me. ////////////// The weather webhooks are already receiving …

I can vouch for @rickkas7 JsonParserGeneratorRK library. I switched to it from the sparkjson library and I have stopped running into stack overflow issues. He added some features I requested which made it easier to use. It’s definitely a better approach to store the raw json string in memory once an…

@rickkas7 I’m trying to get your JSON library working but after reading the Github & looking at the parsing example code a few things are not clear. I think I understand how to get the values from the data the webhook returns after looking at the Parsing example but I’m not sure how I should be se…

You can either remove the response template and send the whole thing down to the device to be parsed, or you can break only the pieces you need, but you need to format the data as JSON. For example: { {{#current_observation}} "location":"{{display_location.full}}", "time":"{{observation_time}}", "…

Perfect, that helped out a lot! The Mustache Tester is very easy to use, thanks for making it :+1: I created the new response template, so it is JSON formatted. The webhook returns data in this format: {"data":"\"Location\":\"Fishers, IN\",\"Time\":\"Last Updated on May 4, 10:54 PM EDT\",\"Weath…

Using JsonParserGeneratorRK, you first declare a parser and buffer as a global variable // Create a parser to handle 2K of data and 100 tokens JsonParserStatic<2048, 100> jsonParser; then in your subscription handler, do something like: void subscriptionHandler(const char *event, const char *data…

I have spent hours trying to get this working but with no luck. Here is the code I'm testing: Particle Web IDE Here is the webhook response: {"data":""Location":"Fishers, IN","Time":"Last Updated on May 5, 3:00 PM EDT","WeatherDescription":"Clear","Temp":73,"Humidity":38%,"Wind":"Calm","FeelsLik…

Your response template should also be valid JSON - your shown template looks like a “mix-and-(not-quite)-match” of XML and JSON.
