3 weeks ago Could you reduce your YAML configuration step by step just for testing. You are using a lot of heavy components (web_server, mqtt, two instances of the jk_bms_ble component etc.). Does the situation improve if you free some resources? Is you custom code stable / free of memory leaks in general?
peff74
commented
3 weeks ago I will follow up on your suggestion. Firstly, I have now removed all my components and then deactivated the web server. I now only have a debug component in there to check the heap
My code used very little heap, the web used much more, now we are at 100KB free heap.
Let's see how it goes

3 weeks ago You could free a lot of resources by changing the log level to INFO too.

something eats the heap and sometimes it comes to a bang...
So it's not in my code or the web server. I have now set the loglevel to Info. Let's wait and see how it reacts.

3 weeks ago Good job!

commented
3 weeks ago unfortunately there were more new starts despite loglevel INFO :-( Where else could I start to find out what is causing the problem?
which is clear, it starts with a significant heap loss
syssi
commented
3 weeks ago Please remove one of the BLE client connections as next step.
peff74
commented
3 weeks ago done
Now we got 114kb free heap. And the largest free block size has increased quite a bit to 64kb. Far right in the picture at 6:30 pm

the view this morning.
A reboot around 10pm since then it has been running continuously
Here is a zoom into the crash at 10pm.
Something seems to be stuck, once he makes it, then the second time it's over

commented
3 weeks ago Could you post your current YAML configuration? I would like to get an idea which components are still used.
syssi
commented
3 weeks ago Some next steps:
jk_bms_ble entities from the YAML but don't remove the ble_client connection. We want still be able to connect to the BMS but we want to skip the data decoding.mqtt component and add the api or web_server component to check the uptime from time to time.The idea is to identify the BLE stack or the network communication as root cause.

3 weeks ago this is then the YAML if I understand Step1 correctly?

now we got 132kb free heap and the biggest block is ~90kb. And very few changes to the heap. I therefore now log every value and not just the changes

the current status.
I had to activate my thermo function yesterday because it was getting too cold.
Since I was unable to set the thermostat via MQTT, it always reset itself to the value I had set on the website, I also had to activate the web server.
Nevertheless, it seems to be stable.
So it seems to be the number of BMS sensors, or one of them has a problem?
What I found noteworthy is that opening the website has such a strong effect on the max block size. I don't know that from Arduino

3 weeks ago It's too early to make assumptions but we are on a good track.
peff74
commented
3 weeks ago What should I do next to continue testing? Can you tell me why the thermostat always gets the values that were last set on the website, even if the web server is no longer active? Do you save the settings on the ESP?
syssi
commented
3 weeks ago Let's stick to two sensors (per BMS) but add the second BMS again.
I'm on the road and cannot provide answers to your other questions ATM.
peff74
commented
3 weeks ago I didn't get around to expanding it today. The system as last described is now running 24 hours stable :-)
I think tomorrow I will add the second BMS again
syssi
commented
3 weeks ago Please keep in mind, we have changed a lot of parameters and a lot of components are running faster now. It's possible the issue occurs on heavy load only.
peff74
commented
2 weeks ago yes I understand, I think we will then add the components back in bit by bit and see what the problem is. Right?
syssi
commented
2 weeks ago Correct!
peff74
commented
2 weeks ago This morning I finally got round to adding the second BMS.
now we got 102kb free heap and the biggest block is ~60kb.
You can now clearly see how the largest block of the heap fluctuates and when the BMS went online, the free memory dropped further.
What I also noticed is that something about ‘cell resistance’ first appeared in the logs, although I didn't even have it active.

I have now added the “cell resistance” to both BMS, i.e. 24 additional sensors.
The memory is shrinking more and more.
Now we got 97kb free heap and the biggest block is ~55kb.
I wonder why adding the sensors eats up so much memory. I only know Arduino. If I take a look at how the data is processed there, then only the data stream that comes via Bluetooth is actually analyzed. Then it doesn't really matter whether I pull 10 or 50 pieces of data information from the data stream, the data is already there anyway.

2 weeks ago Just a guess: The combination of sensor objects and the mqtt component is probably heavy because a topic must be assembled and measurements must be transfromed etc. You could remove mqtt once just for testing and look up the heap at the log to have a comparison.
peff74
commented
2 weeks ago I have tested it out of curiosity. That makes a clear difference!
Just a thought from someone who is not familiar with ESP Home... Would it be possible to run only some sensors/settings through MQTT and make others only visible via the web browser.

Yes. You can declare sensors as internal: true. In this case the state isn't passed to third parties. The web_server component has a special feature to show interal sensors nevertheless:
web_server:
include_internal: trueI have now set the cell resistance as internal: true and for the web server include_internal: true.
The result is no difference, except that the cell resistance not arrives via MQTT^^

https://github.com/syssi/esphome-jk-bms/blob/main/components/jk_bms_ble/jk_bms_ble.cpp#L971-L1006
The frame is retrieved once on established connection and every time if you press the retrieve settings frame button.

2 weeks ago A question for understanding. When I have the switches active.
switch:
- platform: jk_bms_ble
jk_bms_ble_id: bms0
charging:
internal: true
name: "switch ${bms0} charging"
discharging:
internal: true
name: "switch ${bms0} discharging"
balancer:
internal: true
name: "switch ${bms0} balancing"Then I don't need the binary sensors.
#binary_sensor:
# - platform: jk_bms_ble
# jk_bms_ble_id: bms0
# balancing:
# internal: true
# name: "switch ${bms0} balancing"
# charging:
# internal: true
# name: "switch ${bms0} charging"
# discharging:
# internal: true
# name: "switch ${bms0} discharging"
# online_status:
# name: "switch ${bms0} online status"Wouldn't that be double? Because the switches display On/Off
Or are they linked to each other?
syssi
commented
2 weeks ago There is a difference between switch.balancing is turned ON and the BMS is balancing at the moment indicated by binary_sensor.balancing. The same applies to switch.charging. If charging is enabled in general this doesn't mean the protection board allows charging at the moment (indicated by binary_sensor.charging).
peff74
commented
2 weeks ago adding the switches seems to have been too much. or something is wrong with the switches.
I will now leave the switches in and remove the ‘cell resistance’.
Let's see what happens
What always catches my eye is the message of the long loop time of the esp32_ble ~200ms is really a lot. I know this from my Arduino projects, where I split up functions to run them in different loops to reduce the runtime as much as possible. An ESP32 is not as sensitive as an ESP8266, but it's just a thought
peff74
commented
2 weeks ago Perhaps it makes sense to split up the Bluetooth query. The important data more frequently and the unimportant data less frequently.
syssi
commented
2 weeks ago This is a good idea in general but let's check first at some point blocking is really an issue: We will reduce the number of sensor to three pieces again (per BMS) and add a blocking sleep of ~200ms to the loop.
Please keep in mind: The BMS pushs the complete status frame two times per second. We have to discard the traffic because the interval is fix and cannot be changed.
peff74
commented
2 weeks ago O.K. I didn't know that, I thought you had to ask the BMS I haven't looked at the scripts yet, because I know that if I start I'll build my own Arduino version, or make the one from the ‘Akkudoktor’ forum work ^^
At the moment I'm running a version as written above with switch: and binary_sensor: and less sensor:

2 weeks ago I had a similar issue during this year. ESP restarted several times randomly (?). I started commenting sensors/switches but nothing. At least, I created a custom component "switch" (JkRS485BmsSwitch) and a custom component "number" (JkRS485BmsNumber) and everything went OK (with all sensors uncommented).
I cannot undestand why the problem dissapeared using custom components...
Now, I have a similar issue with sensors. I have tried to create a new custom component "sensor" (JkRS485BmsSensor) but I have not got it to know if this way the problem goes away for ever. :-(

I received the logs via the network. Because the ESP runs outside in a small cabinet, it's a bit difficult to connect it serially. But if it becomes necessary, I could build it.
To get exception and stack trace logger
level: DEBUG
must be active?
I don't know ESP-Home very well.

Sounds like you are connected over cable, I use BLE.
I am not sure if this is comparable.
When expanding my system, I noticed that the ESP restarts quite frequently. As I don't have any experience with ESP home devices... I can't judge whether this is normal.
The last reboots are mine, I wanted to get some logs.
But I can't really see anything in the logs, the device just restarts. I had already replaced the hardware on suspicion, a WT32-ETH01
here my YAML:
or do I have too many sensors or other errors?
