@GasGen This may be a better place to continue this discussion. Here is how I have my setup working. First the Particle Integration: [image] Next is the individual device setup page: [image] [image] And then the workflow settings that separates the incoming webhook data into individual vari…

Thank you so much for all your time Ryan. So is your webhook name state? or is it newState? Here is how my data is sent from Particle. EF is my webhook event name… cf is the json form field in the webhook, and F is the data sent. Particle.publish("EF", "{\"cf\":\"" + F + …

[image] GasGen: So is your webhook name state? The webhook name is: state Here is what the Particle Publish code looks like. snprintf(publishStateString, sizeof(publishStateString), "%.2f:%.2f:%.2f:%u:%.2f:%.2f:%u:%u:%.2f:%u:%.2f:%.2f:%.2f:%.2f:%u:%u:%.2f:%.2f:%.2f:%.2f:%.2f:%.2f:%u:%u:%u…

WOW. not thats a long one. lol Yea @ScruffR taught me how to map floating numbers… save me from pulling my hear out by simply adding a decimal. This is how mine is written. float flow = map(adc,2139.0, 10614.0, 0.0, 200.0); String F = String::format("%.1f", flow); if (Particle.connected() && mill…

This is the original code that has the other variables commented out as I don’t need them published right now. Trying to maximize data. This was how I had to write the string to get it into the webhook and over to google sheets. Particle.publish("EF", "{\"cf\":\"" + F + // …

Try this. #1 Create a Global Variable by placing this line of code above Setup(). This creates the bucket to hold the data we put into the publishStateString bucket. It's large enough to hold all the data a Webhook can hold in a single Publish Event which is 255 bytes. char publishStateString[256…

I (obviously) second @RWB ’s suggestion to use char arrays instead of String. Just one note about the readability of very long snprintf() lines. snprintf(publishStateString, sizeof(publishStateString), "%.2f:%.2f:%.2f:%u:%.2f:%.2f:%u:%u:%.2f:%u:%.2f:%.2f:%.2f:%.2f:%u:%u:%.2f:%.2f:%.2f:%.2f:%.2f:%…

Yea, it’s a beast to try to follow :smile: I actually created a spreadsheet to keep track of it all which helped. [image] I was surprised how much data I was able to pack into a single Publish Event using the semi-colon spacing as the separator.
