Bluetooth Lifepo4 batteries about renogy-bt HOT 37 CLOSED

I see, makes sense. Looks like BT-2 doesn't allow long read values. I might have to modify the code to read it in batches.

from renogy-bt.

hi Cyrils, it looks good this time. Below is the output for both controller and battery. One suggestion to make the code better is to check if the output is good, e.g. no connection failed...etc. If not, make a loop to run the code again. Just my 2 cents :)

Sure, it might take several iterations, but I'm happy to help. I'll let you know when there is a branch ready to test.

from renogy-bt.

@sven253 Please checkout the branch battery, modify config.ini, run example_battery.py and let me know the output log. If it doesn't work try changing the DEVICE_ID in BatteryClient.py to 247 (or whatever your app shows).

Please note this is super early version and it may have many bugs.

thanks for your fast response! I used DEVICE_ID 48

if i use 247 i dont get any output after connecting. where can i see the DEVICE_ID of my device?

from renogy-bt.

I've updated the branch, lets try this again.

Device Id is usually found on the bluetooth app connected to the device.

from renogy-bt.

In the Renogy DC Home App?
I got this output:

I haven't tried the Home DC app as I don't have a battery. The renogy bt app shows device Id in the 'device info' tab.

Looks like its reading the cell voltages correctly. I've pushed in some fixes for remaining fields, let me know if its working.

from renogy-bt.

I tried the Renogy App but it doesnt support batteries. I dont get any battery information. In the device info tab theres is only my battery name.
I tried your latest push it works! Thank you!

Great, I will do a refactor later sometime to push these changes to master , you can continue to use the branch in the mean time.

Can you also do a favor let me know the exact battery model you have? I could add that to the list of supported devices. Some other battery versions seems to have a different mapping of fields (mentioned here Grmume/renogy-smart-battery) not sure how is it different from your model.

from renogy-bt.

I have this one:
RBT100LFP12-BT-DE
https://de.renogy.com/12-v-100-ah-lithium-lifepo4-akku-mit-bluetooth/
Should be the same as this one:
RBT100LFP12-BT-US

from renogy-bt.

i found a little bug:
it shows current: 653.96 but it should be 1,5 A
Can you try to fix it?

Can you replace BatteryClient.py#59 with the following and let me know the output?

Sorry my fault. i used the wrong python script. Everything works great! Thank you!!!

from renogy-bt.

its a little bit off topic but i changed your code a litte bit to fit my needs. I want to search for bluetooth devices till i find my battery because my battery is portable and not allways in the bluetooth range of my pi. i created a service to call your script and start it automaticaly with pi. my python skills are pritty low. Can you take a look at it? its working but i am wondering if this is a good way to do it.

This is the part i changed:
BLE.py
` def discover(self):
discovering = True; wait = DISCOVERY_TIMEOUT; self.device_found = False; mac_address = self.mac_address.upper();

    self.update_devices()
    logging.info("Starting discovery...")
    self.start_discovery()

    while discovering:
        time.sleep(1)
        logging.info("Devices found: %s", len(self.devices()))
        for dev in self.devices():
            if dev.mac_address != None and (dev.mac_address.upper() == mac_address or dev.alias() == self.device_alias) and discovering:
                logging.info("Found matching device %s => [%s]", dev.alias(), dev.mac_address)
                discovering = False; self.device_found = True
        wait = wait -1
        if (wait <= 0):
            self.stop_discovery()
            logging.error(f"No device found wait {NONSTOP_DISCOVERY_TIMEOUT} seconds")
            time.sleep(NONSTOP_DISCOVERY_TIMEOUT)
            self.discover()
    self.stop_discovery()

It should work, but might lead to a never ending loop in case battery is not reachable. The method I have is a little different, since I do not want real-time data.

I have turned off polling in config.ini and scheduled a cronjob (crontab -e) like this :

*/5 * * * * /path/to/renogy/example.py 

This will run every 5 minutes.

Hi all, I got a Renogy 100AH Smart Battery (RBT100LFP12S-BT-UK) with the BT-2 module. If 48 is used as Device ID, the output is 37182 cells with all zeros. No output if 247 is used. Just wonder what's the correct Device ID? I can't find such info in Renogy BT app. Any help is greatly appreciated. Many thanks!

from renogy-bt.

@pedrong1025 Currently only battery with built-in bluetooth is supported. However if you can share the logs may be I can take a look.

Update BatteryClient.py#31 with following code and let me know the output:

logging.info(f"on_data_received: response for read operation {value.hex()}")

from renogy-bt.

Hi Cyrils, thanks for your reply! Here is the log. Once again, thank you very much for your help!

Unfortunately that didn't give much information. Can you try changing the following in BatteryClient#14 as well and let me know the output log:

READ_PARAMS = {
    'FUNCTION': 3,
    'REGISTER': 136,
    'WORDS': 30
}

from renogy-bt.

Hi Cyrils, thanks again for the feedback! I changed the code but unfortunately got the same output. Anything else I can modify to make it more informative?

Looks like the register value 5000 is correct. Not sure why its not returning any data. Is this tool working for you? https://github.com/chadj/renogy-smart-battery

Lets revert to:

READ_PARAMS = {
    'FUNCTION': 3,
    'REGISTER': 5000,
    'WORDS': 17
}

Do you have any other devices like charge controller/ inverter? Are you using communication hub? The response you are getting is a read error: 0x83, 0x02 - PDU start address is incorrect or PDU start address + data length is out of the legal range, meaning profile is not matching with battery.

from renogy-bt.

Hi Cyrils, after changing the code to,

READ_PARAMS = {
'FUNCTION': 3,
'REGISTER': 5000,
'WORDS': 17. ### The original code is 48
}

I got more informative output. Is this you are looking for?

Regarding your questions,

1. Yes, I got a controller. I can get voltage, temperature ...etc by using your code.
2. No, I don't use any communication hub, just use BT1 for the controller and BT2 for the battery

Thank you very much for your help!

Hi Cyrils, if I change the words to 24, I get more meaningful output. But the value of current, voltage, remaining charge and capacity are zero.

I did some refactoring to make it more robust. Can you pull from battery-bt2 branch again and let me know if tis working? I will port it to master depending on that. (config.ini has a new type field now)

Ah.. ok. Does that work if we change cell_volt_info words to 18 and cell_temp_info words to 17 (BatteryClient#21-22). Sorry its taking some iterations.
