All my Shelly devices are linked to the Shelly cloud account. Here's what I did.

- I'm using the Android app to manage the devices.

- If I ask the Android App to check for outdated firmware via the "⟳ Update Devices" menu item, it will list all outdated devices and allow me to update them all at once. As expected. Great!

- After this, all devices disappear from the "⟳ Update Devices" menu, even if I "Check for Updates" again. As expected. Great!

- Now I'm going back to the "Welcome" screen and click through to my "Plus H&T" devices.

- Weird: All my "Plus H&T" devices still tell me "Firmware Update Available" in their individual screens

- Weird: If I click "Update" there, the app tells me that the device is updating and after a while, stops telling me that the update is in progress. Did the upgrade succeed? The app doesn't report an error.

- Weird: The firmware version doesn't change and if I go back to the "Plus H&T" device, the app tells me "Firmware Update Available" once again.

- Weird: If I go to the "⟳ Update Devices" menu and "Check for Updates" there, the "Plus H&T" devices will not be reported to me.

In order to actually update the "Plus H&T", I have to use the "Update" function of the app and then click the Reset button on the device in order to change it into setup mode. Then the update works.

Meanwhile, the "Flood" devices on the same cloud account all updated smoothly with no problem and no need to push their reset button.

Also, is a one time calibration enough or will I have to recheck the values and then recalibrate the device on a regular basis?

Why does it need an offset? How am I supposed to determine the offset? Why doesn't the device come properly calibrated from the manufacturer?

I bought three Plus H&T. The original humidity values were off the charts too high, now with the current firmware they seem to be more realistic. But still they look like guesswork and are higher than compared to the measurements of this other, cheaper device. The photo shows a Plus H&T with the current firmware. The device on the left is a fairly cheap device that isn't calibrated, either. So which of these devices do I trust? And what do I do to find the actual humidity value for my rooms? How to calibrate the Shelly?

Thanks. The firmware update indeed fixed the humidity values, these are much more plausible now.

However, I still don't get the rationale behind the minimum & maximum temperature value.

Your devices are fairly powerful, some of them even contain a full webserver. Even if saving battery requires them to send messages over WiFi as rarely as possible, I assume the devices still have enough resources to store more than just two temperature values between message sending. So even if the device waits an hour between message, why not send an array of temperature measurements with each wifi message?

Hi there,

so I bought five Flood sensors and three Plus H&T. They work nicely, one Flood sensor already averted a leak recently, thanks for that. Except the humidity sensors of the Plus H&T seem to be way off and it would be nice to have a reliable method for calibration that's not just an offset value.

What's weird to me is that the application tracks a "minimum" and a "maximum" temperature graph for both the Flood and the Plus H&T.

Why are there two different values? After all, there's just one temperature in the room at any time (and the Plus H&T shows only one temperature value on its internal display). I would have expected the devices to return a single temperature value only and report it whenever there's a configurable change in temperature.

What am I supposed to put into my home automation system with these two values when they differ? Shall I just use the average of them?
