Value formula, seems to work, but can anyone confirm?

[Strider336]

I have an AM2302 sensor attached to a NodeMCU3, running ESPEasy (v2.0-20180113), i'm using to monitor temp/humidity in my garage and control a dehumidifier on a Sonoff switch (running 147) on the other side of the room.

The problem I have is the sensor is horribly inaccurate, temperature is OK, but relative humidity reads around 55% when it's actually 65%, and reads around 45% when it really is 50%.

I really wanted to add a percentage to the value, and noting that % is not an option, I've used formula %value%/100*15+%value% to increase by 15% (actually needs to be more like 20%, but later), it seems to work, but the use of long formulas does not seem to be documented at https://www.letscontrolit.com/wiki/inde ... asyFormula

It works, but I do wonder if there's a reason it's not documented? Usually if something like this is omitted from documentation, then it's for a very good reason.

I don't think your formula is very long, complicated or unusual. The wiki only explain the formula functions in general terms.

I know, but i'm just careful since I bricked a NodeMCUV3 for no apparent reason after adding a new rule.

That must have been a corrupt settings file or similar? Don't see how you could brick the unit really.

It got to a point where it refused to start, serial data showed it was stuck in a loop, reflash wouldn't fix it, the only solution (which I read about on some forum) I didn't try was reflashing the original NodeMCU firmware. But that's not really a problem, I just want to avoid screwing up any more of these boards.

A blank bin file flash solves most corruption problems.
