Latest version of controller code only supports V2 of influxdb

[jbuszkie]

There are a lot of us out there that don't want to/ can't upgrade to V2 of influxdb.

It would be really nice if we had the option of staying with the 1.x implementation.

Hello, if you are running v1.8 or newer of Influx, it should support the forward compatibility interface.

https://docs.influxdata.com/influxdb/v1.8/tools/api/#apiv2write-http-endpoint

In InfluxDB 2.0 uses API Tokens to access the platform and all its capabilities. InfluxDB v1.x uses a username and password combination when accessing the HTTP APIs. Use the Token schema to provide your InfluxDB 1.x username and password separated by a colon (:).

For example: username:password.

When I get my esp32 version of the controller up and running, I'll have to try this.

[jbuszkie]

If someone can test this and verify, then we can close this (hopefully) non-issue

[stuartpittaway]

Has anyone tested this?

[jbuszkie]

Has anyone tested this?

Not me.. I don't have an ESP32 controller yet..

hello,

just tested it with influxdb 1.8 on a windows10 machine.
Logs each cell b,e,i,v values
to my understanding:
e is external Temp
i is internal Temp
v is voltage
b is empty and haven't got a clue at what it's meant to measure!

So assuming that's what it's meant to log, it's working :-)
good job!

BTW, BMS is connected via CAN to Victron (raspberry pi 3B+ running VenusOS 2.80Large) and through that I also get bank voltage/current/watts and all warnings from the system as sent to Victron. Wonder if they should also be sent to be logged directly from the bms influxDB interface?
Is there any documentation on what is actually being sent to influx?

cheers
V.

still works without crashes in diyBMS 10h later. Excuse the regular jumping about it's 4 lifepo4 modules connected to one half dead 18560 cell each with some tiny cables, when it starts balancing all hell breaks loose.
I'll come back on this on what would be nice to be sending to influxdb as I think v and temps are not really enough.

hm, influxDB works fine, but now controller started rebooting. Was away from the pc, will try to note down how often/when it reboots. Sadly cannot easily pick it up/record it from influx...
Uptime was in days before starting influx, now it's in hours, guess it's related.
One thing I'd like to see is being able to set the interval for sending data to influx. Now it is like every few secs, don't see any reason (other than debugging) to have such dataflow. Would be happy with 60 secs as I do for all my NMEA2000 data logged via Victron.

looks like circa 2h between controller reboots.
b is inBypass which I guess is either false or true.

Hi, there was a bug on the influxdb which was fixed a few months. Are you running the latest version?

I really could do with the latest version being applied and then the serial port log files being captured when the reset happens.

[virtuvas]

yes Stuart, I'm aware of that, running the latest version (loaded it 4-5days ago):

Host name:DIYBMS-004CE8AC

Processor: ESP32

Version: 1dde4670aecf5ea29f773a964928492e5fb5d035

Compiled: 2021-12-06T15:10:39.269Z

Language: language

SDK Version:v3.3.5-1-g85c43024c

Min free Heap:86360

Free heap:102404

Heap size:296744

for now I'm trying to log reboots (not easy when not working on my desk though...), changed to a powerbrick for the ESP32 (plan to get it running from the pcb power input tomorrow if I have time)
If you can explain how to do a serial port log, I'll be happy to help.

since yesterday I had (at least recorded maybe a few more I missed):

19:15
20:03
22:15
03:50
09:38
11:15
13:03
mostly doing bugger all, did try to charge the 4 18650cells a bit, now just let it run and see

I'd also be happier if we could sent to influx on set intervals (like 30s or 1m) - don't want all this traffic from the RUT240 onboard nor the data charges... Shall I put up a new issue for that?

cheers

V.

[stuartpittaway]

Yes please raise a new issue for the influx timing.

[virtuvas]

OK, will do, now how do I log serial port log? any pointers?
