Hello, I am wondering why I have over 12000 messages (writes)per day to a channel which I only update all 8 fields every 20 minutes. Or are these statistic timely delayed? Since testing I might have more writes, but now with my ready weather station only every 20 minutes my data will be updated. Wetterbox Channel ID: 2391212 Access: Public Can you explain this to me? Thank you for your help. Regards, Julian Too many messages per day, free account If I read your channel, I see 71 messages from today, and 87 messages from yesterday. howMany=size(thingSpeakRead(2391212 ,"numdays",1, "outputformat","timetable"),1) howManyTwoDay=size(thingSpeakRead(2391212 ,"numdays",2, "outputformat","timetable"),1) howManyTwoDay-howMany=howManyYesterday The total number of messages in your channel right now is about 12,000. I read 8000 of them, the first date in the last 8000 readings is Feb 27 2024. By any chance, are you exporting the data in the channel, clearning your channel and re-importing the data into your channel? Once you update a channel, you use a message. Clearing the channel and reimporting the data just results in double the usage. If you do the clear & re-import "n" times, you are just using "n" times more messages. Thanks for this explanation. True during my testing phase I needed clear and upload data again. This makes sense. Good to know, i'll need to test messages channel update free account
