Hello friends,
can someone here from the forum, create me a modified Ruuvi firmware update?
It should be OnTheFly on playable! Like the original updates from Ruuvi.
Minimum version 3.30.4+default or version 3.31.1.
Namely, the update must receive the following change.
1 x humidity + 3 so, instead of 47% humidity, the value must then be 50% humidity.
1 x humidity + 4 so, instead of 47% humidity the value must be 51% humidity.
1 x humidity + 5 so, instead of 47% humidity, the value must be 52% humidity.
1 x humidity + 6 so, instead of 47% humidity, the value must then be 53% humidity.
Who can create this for me against PayPal payment and send it by e-mail?
Agreed payment will be made via PayPal, after verification.

Would think its better to do the “calibration” on the receiver side, or make a firmware that have a “calibration” value

Since the RuuviTag Basically display too little humidity
(software problem?) is a firmware that simply compensates the difference roughly in my opinion the easiest.
Therefore my request.
No problem to understand the frustration, but my experiance is that you need to create a calibration curve. The (+5%) is not linear you might even need -2% when at 10% humidity.
I have BLE sensors from 4 different suppliers on my desk and they show:
Ruuvi - 12.9% (cover off)
Ingics - 7% (cover off)
ELA - 9% (Closed with membran)
Kanki - 8.5% (Open construction)
at 23°C
Yes i know its a very dry office 
Yes, for my applications the temperatures are around 18-22 degrees and the humidity 40-60%.
This then allows you to adjust the values.
The whole issue is not so simple.
