Thanks for the info. I suspected it was a clean install as the solution. Luckily, I have the email saved showing both System ID and Activation code.

While I was waiting to decide what to do with meteohub, I checked out WeeWx, which is currently under evaluation.
In the process, I upgraded the ...

I have relocated to a new geographic area, and it makes no sense to retain old data.
As the title asks, should I start with a new installation or just clear out old data?

Currently RPi Model B with Meteohub 5.0i

If I install the current version 5.0s, will it activate with the old activation code ...

Use this link to see if you can find your memory card. http://elinux.org/RPi_SD_cards
Also, you say SD. Do you mean microSD for RPi2?

64GB is the largest memory size that can be used in RPi2, as best I can determine. I am successfully using 16GB since Meteohub is a standalone appliance. I don't expect it to do anything else.

Dane Elec, or now Dane Gigastone, DA-SD-1016G-C works. Also, new install of 5.0f autosizes the data partition to use the remainder of the memory space.
Boris, very clever, thank you.

At this point, the rasppi is very experimental, feels much slower than the fit-PC slim, especially during recompute ...

Transcend TS16GSDHC10E fails.
PNY 16GB works. Probably MLC. http://www.amazon.com/gp/product/B0090YT6F2

SLC microSD cards are rare and expensive. SLC SD cards are not as rare and certainly not as expensive, although not as cheap as MLC or TLC.

I am experimenting with this adapter: http://www.amazon.com/gp/product/B00L9OB95G
I have modified the Vilros case and successfully booted up with the original ...

Does Meteohub running on RPi 2 accept an external USB thumbdrive and recognize it as temporary storage?

Also, are there any known SLC microSDHC 16GB cards? What about known SLC SDHC 16GB cards?

Should I anticipate problems using MLC cards?

In hardware overview there is this: "recommended SD Card: Transcend TS16GSDHC10"
Can I use TS32GSDHC10? I cannot find specification which says it is SLC. Does SLC/MLC matter?
[edit to add]
I see RPi Model 2 uses microSD format. What is recommended for this model?

I will eventually upgrade from fit ...

There does not appear to be anything remarkable about meteohub running double NAT. My setup is running on a secondary router connected WAN to LAN with no problems. The only port forward I have on secondary router is port 80 for remote admin since my primary router contains most of my device ...

Solved. Changed sensor type to t1 which is temperature only. Single parameter was returned from difference calculation. The th20 sensor type was expecting more data.

Meteohub log shows
logger (20.05.2012 00:00:17): computation of virtual sensor "th20" with values "6" failed: Wrong number of parameters: "temp[1/10C]* hum[%]* dew[1/10C]" (* = mandatory, others can be replaced by "-")

meteohubsensors.png I have a series of sensors, two of which monitor the temperature on both sides of a solar collector. These are th12 and th13. I have tried to create a virtual sensor that displays the difference between the two by following the write-up in the meteohub 4.7 documentation. I'm ...

Once it's pointed out, it's so obvious.

Thanks.
