Jeti RFID Battery-logger

Thanks for the answer. What about the operating voltage? Can I come without adjustment with 8V?
As I understand the system here, the capacity data is read by another sensor and written to the RFID chip. Could one also read further values ​​from the sensors and write on the chip? In my helicopters I have a JLog 2.6 with a CVS16 which monitors the individual cells. As a telemetry value, I then have the info, which cell was weak and how its cell voltage is.
The topic with the Junsi interests me then also, as soon as you have a solution. It would also be interesting to write the loaded capacity on the RFID chip.

The capacity-value written to tag is battery capacity, for a 6S 5000mAh the capacity on RFID-tag is 5000. No Cpacity (current)-sensor required for that, the "capacity" on RFID-tag is just for information (and in LUA for automatic alarms).

Only thing written to RFID-tag during flight is the "Cycles"-value, new value is is written to keep track on battery-cycles.

We can not tell RFID-Sensor to write something from transmitter (like consumed capacity) since that's part of the closed part of EX-protocol and I don't have it. And if I had I could not share it since it's closed. The open part of sensor-protocol does not allow us to write anything, only way we can tell the sensor to do something is Jetibox and that cannot be operated during flight.

Don't hold your breath on Junsi RFID, it may take some months

Revo Bump tag is almost fully decoded

Jeti RFID-Sensor + Revo Bump is coming along nicely, I know some of you are waiting so I thought to post a progress report after this evenings break-through.

The base-code for Revo tags is ready!

There's still work to do, I need to find a way to transfer the battery name to Jeti and make some safeguards based on what tags you are using.

My goal is to make LUA-app fully automatic, Revo Bump users does not need to put any ID's of tags, only the sensor- and alarm-settings. (This of course if I can make it work ,I do have some ideas for it.) As a backup Revo Tags might need a manual entering of the "short id" in Revo Bump controller to every tag but that is no biggie to anyone so we have a safety-net there.

There might come changes in the code, Revo have promised information on their tags data-byte locations, I have not received that yet so I decoded the tag myself. There are two things that might be wrong regarding byte-location but after getting the data they are easy to update.

With a little luck this should be ready this week for publishing

This is where we are today:

Revo Bump is now compatible with Jeti

Now you can use Revo Bump battery-tags with Jeti RFID-Sensor and with RC-Thoughts Jeti Tools LUA-App RFID-Battery for DC/DS-24 to get more user-friendly battery-alarms (capacity, empty flight-pack before flight) and on top of that spreadsheet-software compatible logs on battery-usage on battery level regardless in what model you used them. (Log is platform independent!)

All code is free to use, hardware is very affordable (under 10€ per sensor) and schematic is available. This version of code will be up shortly, just finished it an hour ago.

Here’s a run-down of functions:

They have really solved very nice am really strained where all this can still lead us. Very nice videos. Thank you very much.
Yours sincerely
