Just bought 2 XT300 soil moisture sensors for my plants.
The % humidity keeps rising instead of becoming less during the time. When I add water, I see a peak, some time later a drop and then again it starts rising.
Both the sensors acts the same.....

Any thoughts on this??

I think I read somewhere that they are autoadjusting, have patience

This is what one of my sensors show, guess my wife was away the 24'th. "seems i snipped it a bit short, green is moisture."

Hi Nettime,
Thanks for the response. Lately the line seems to make more sense, the range is between 95% full wet, and 70% for dry.
I dont onderstand your trend. Slowely raising grom 24th april, and then a steady line. Do you water your plants daily?

Hi all,
also for my project I have some trouble with the opus/xt300 data sensor,
sometime data seems to be correct but in the next time the data goes wrong (temperature: -40, and channel 0). This because the rtl_433 receiver can analyze the wave but it can't decode the signal and catch 0 values for moisture, temperature and channel...(into the script the temp was tem= 0 - 40--> then -40)

in your opinion what are the causes of these wrong data?
thank you!

Hi All,

curious issue with the XT300 : I purchased one unit over a year ago which i found to be really good. Placed it outside and it worked consistently well throughout the year, through the hot months and cold months, so i just purchased an additional 3 units (with one to spare in case one gets broken).
All three units I received are showing a value of 99% for humidity, almost constantly. It sometimes goes down to perhaps 94 but it doesn't seem to be in relation with the wetness of the soil. I actually put my old one together with my new one and my old one is reading 32% while the new one, 99% as always. I would have put it down to a faulty unit but all three units are showing the same thing? Is it possible i've purchased all three from a faulty batch?

how can you see 2 graphs in the same? im interested to do that as well!

You mean Temperature and moisture together? That will be shown if you open the log of the combined Temp+Hum device.
