Or I thoguht so... As you say, maybe it depends on the temperature, because it goes up or down and sometimes it's out of the range. Kind regards

Hi, Alex. It's 1.1.0. I have changed the batteries and the interferences have gone. Thank you very much. Juan Carlos

It goes up and down depending on the day and the hour.

Thank you very much. I have sent the device by post this morning.

Sorry. My English is not good enough. I thought that it just meant to write the new firmware over the old one. If you tell me where I should mail the device I will try to do it as soon as possible.

Mail the device means to send it to you?

Great! Thank you very much!

That you very much. I will contact the shop and ask about the issue.

What is most strange to me is that in their webpage they have a photo of the 1.1.0 version and that was the reason I acquired the device from them. What should I do according to you?

In a Spanish shop, online (due to the sanitary restrictions).
