Thx for this tip. I will try, hovewer I put the values in SG but I would need resulting formula in plato because iSpindel displays plato in 2 decimal points. Also don't know if apps where ispindel sends data does not require gravity in plato. Maybe a switch in calculator would be fine to display...

Hi does anyone know how to make calibration formula properly using this tool ? http://www.ispindel.de/tools/calibration/calibration.htm I want to use Degree 3 formula but this tool returns a formula in SG and not the Plato. Then iSpindel shows SG instead of Plato which is not good. The excel...

Thank you. Yes, it's strange with that RSSI. Recently I've installed a repeater (in roaming mode), pretty close to the router an it shows RSSI usually about -60 to -70 but despite of this I have sometimes a blackout. It's not reporting maybe for an hour, then it starts normally. So I'm not sure...

That's pretty nice result. What is your RSSI ? I've noticed if I put it next to the router it's -40, but 2m away is already -60 - is this normal? In plastic fermetor I have usually -75 RSSI. For me it looks like this chip has a very poor wifi range. I also have 10 min interval and battery goes...

Thank you!

Thanks for response. I've bought a repeater already :) I want to ask also about battery life. It shows 4.25V when it is fully charged and then it goes down slowly. I have 600 seconds interval. What's the lowest voltage when the device stops working ? Thx

Hi guys, I've just build and calibrated this device and it works pretty good, however I've noticed that data are not transmitted to the ubidots all the time. If I lay ispindel freely on the table maybe 5m from router with very thin wall, it shows -60 RSSI. Seems it sends data reliably. But if...
