Merge #129 first. This branch sits on top of it (both touch zWebPage.h and the same README row), so until #129 is merged this page also lists its commits.

What changes for Renato

• UM982 temperature. The Teensy now asks the UM982 for HWSTATUSA (its hardware status) every 10 s, the way it asks a u-blox for UBX-MON-SYS, and shows the temperature on the Status tab (GNSS card, a row under the receiver) and on the GPS tab. Before, that row read not reported for a UM982.
  • The number comes from the first field of the answer, divided by 1000: your receiver sent 59493 → 59 °C.
  • This is a deduction, not something Unicore's manual says (what could be read of it does not name that field; its example has 66807). To confirm it: the first answer after start-up goes to Messages with the number as it came, e.g. GPS receiver: temperature 59 C (UM982 HWSTATUSA, first field 59493, …). On a cold morning that number should start clearly lower and climb as the box warms up.
  • Safe-guards: a line with a wrong CRC is dropped; a value outside -40 to 125 °C reads not reported; the poll goes between RTCM messages, waits while the page reads or writes the UM982's settings or while you type a command in the UM982 console, and its answer stays out of that console. A UM982 firmware that does not know the command is asked three times, then left alone.
• Network name with a hyphen: the Teensy announces itself as AiO-FBCA (was AiO FBCA), written like XIAO-… and Sprayer-…. This is the name in AgOpenWeb's web cards list and on the Connections card. http://aio.local/ does not change.

Nothing in the steering, the GNSS output or the safety code changes. The new code runs from flash (FLASHMEM), so RAM1 keeps its room (the "Teensy firmware" check prints the figure).

Not compiled with the Arduino tools (not reachable from the cloud). It builds and links here with arm-none-eabi-gcc and the Teensy core, and the "Teensy firmware" check compiles it at 450 MHz. The .hex is yours to export (CPU 450 MHz) after both pull requests are merged.

How to test

1. Compile (Teensy 4.1, 450 MHz) and install.
2. Messages, about 10 s after start-up: GPS receiver: temperature NN C (UM982 HWSTATUSA, first field NNNNN, read as thousandths of a degree).
3. Status → GNSS card: a temperature row under the receiver. GPS tab: the same value. It follows the receiver every 10 s.
4. GPS tab → UM982 console: type VERSIONA. Only its answer shows, no HWSTATUSA lines in between. The UM982 settings still read and write as before.
5. Cold-start check (when you can): note the "first field" number in Messages on a cold morning, and again after an hour of work. Lower at first, higher later = it is the temperature.
6. AgOpenWeb → web cards → ⚙ → Search the network: the module is listed as AiO-FBCA.

Checked here: the parser run on a PC against your real answer line (59 °C), a damaged line (dropped), a negative value, an out-of-range value and a non-number; simulator smoke test (the pretend UM982 shows 59 °C, the name reads AiO-3F2A); changelog check.
