Soil moisture graph

[insippo]

I use mysensors soil moisture driver. All is ok but domoticz put graph to temperature menu and write to graph window Temperature last 7days, Temperature last month, and year. How to change this?

[gizmocuz]

Your using a 100% copy of the MySensors soil example? Or are you also sending other sensors ?
if it is a copy, it should work... i think... i do not find it a good sample...

How about you change the presentation from S_HUM to S_MOISTURE ? that should give you a better sensor i suppose

[insippo]

Yes.100% Mysensors example. Only soil moisture. Where i change S_HUM to S_MOISTURE ? In mysensors arduino sketch ? Oh. Too many questions.

[trixwood]

Yes in the sketch.

[insippo]

Okay. I change after work.

Here is V_HUM and S_HUM. What exactly needed replaced ?

[trixwood]

I would try the S_HUM as gizmocuz suggested. If that don't work change the other one too. I have no Idea.

You got this one from: https://forum.mysensors.org/topic/2147/ ... /24?page=1

Cuz the official one looks very different.

https://github.com/mysensors/MySensors/ ... Sensor.ino

Well, all the better, i am building that one too! at least if the last parts arrive from the hung dynasty.

The only thing I want to change is sleeptime/delay vs rate of change for smoother graphs. But that probably will reduce battery life at least half. Brainstorming away...
