How to setup ESPHome from scratch #327

moscito1010 · 2023-05-08T14:19:28Z

Hello
Can someone link me to instructions for an absolute beginner so that I can get the code on an esp32.
I've tried it for a while now but I don't have all the basics to do it.

I have a NEEY bms 4th 4A and would like to visualize the BMS data in Home Assistant. Unfortunately, I've really never worked with plattformIO and Visual Studio. For me it's like sitting in the space shuttle and it should land :-)
Since I don't know at all how to proceed I could use a simple good guide. Preferably a YT post.

Do you have access to an Linux host? Visual Studio isn't required. A few console commands should be sufficient:

https://raw.githubusercontent.com/syssi/esphome-seplos-bms/main/install.gif

Use a x86 based Linux host. Please try to avoid a Raspberry Pi because of the CPU architecture
Make sure python 3.x and the python package manager (called pip) is installed
Install esphome using the package manager pip3 install esphome
The to execute the command line tool esphome type: ~/.local/bin/esphome
Create a directory for your esphome configuration YAMLs: mkdir ~/esphome
Download the Heltec Balancer configuration example: cd ~/esphome; wget https://raw.githubusercontent.com/syssi/esphome-jk-bms/main/esp32-heltec-balancer-ble-example.yaml
Update line 5 (the mac_address) to the MAC address of your balancer
Create a secrets.yaml and provide some required secrets:

cat > ~/esphome/secrets.yaml <<EOF
wifi_ssid: MY_WIFI_SSID
wifi_password: MY_WIFI_PASSWORD

mqtt_host: MY_MQTT_HOST
mqtt_username: MY_MQTT_USERNAME
mqtt_password: MY_MQTT_PASSWORD
EOF

Run the YAML using the esphome CLI (means: compile & flash the config): ~/.local/bin/esphome run esp32-heltec-balancer-ble-example.yaml
Have fun! :-)

I'm really blown away. Thank you for your quick help.
In fact, I only have Linux on my various Raspberry, but I'll quickly create a linux partition and install Ubuntu.

moscito1010 · 2023-05-08T14:54:57Z

oh wait. I have a NEEY balancer that only has bluetooth.
I wanted to use the ESP as a BLE2WIFI bridge.
Did I misunderstand the project? I thought it was about using an ESP32 to implement communication between the balancer and e.g. Home Assistant.

moscito1010 · 2023-05-08T14:59:10Z

forget it, I think I got it now :-)

syssi · 2023-05-08T16:37:16Z

Your understanding is correct. The mentioned YAML talks to your NEEY/Heltec Balancer via BLE and publishs the received measurements via MQTT. The command topics can be used to control the balancer (settings / switches).

moscito1010 · 2023-05-08T17:04:32Z

Something is still wrong.

~/esphome$ ~/.local/bin/esphome run esp32-heltec-balancer-ble-example.yaml

I adapted the config on my board with the information from the website https://registry.platformio.org/platforms/platformio/espressif32/boards

Of course that's not my password :-)

what i should mention i have 5 balancers. do I need an ESP32 for each balancer?

I also use an ESP32 for another project to control my Bluetooth heating valves, so I can connect 6 devices to one ESP.

moscito1010 · 2023-05-08T18:22:18Z

quotation marks had to be set. It took me a while to understand :-)

moscito1010 · 2023-05-08T18:55:42Z

I give up.
This doesn't work on my system and I'm sure that the error is in front of the pc.

I have to find someone to flash my ESP. I obviously can't do it myself and you're not ESP support.
Many thanks for the help you provided.
Let's see if someone in the ESP forum can help me.

Es lies mir keine Ruhe also habe ich es heute früh nochmal probiert.
Ich nutze meinen PC (Ryzen CPU) mit Ubuntu 18 lts. Ich habe apt update und upgrade vorher ausgeführt.

Ich hab Schritt für Schritt nach deiner Anleitung gehandelt aber ich komme zu keinem brauchbaren Ergebnis.
(Schritt 7) Die MAC Adresse vom NEEY habe ich mir in Ubuntu anzeigen lassen und in der yaml eingetragen .
(Schritt 8) Das Erstellen der secrets.yaml ist auch klar.
(Schritt 10) Die secrets.yaml wird aber von ESPHOME später nicht akzeptiert, das WIFI Passwort soll laut Fehlermeldung in Anführungszeichen angegeben werden. Ändere ich das scheitert es daran das 'espressif/toolchain-riscv32-esp @ 8.4.0+2021r2-patch2' nicht gefunden wird.

Auf einem Laptop habe ich es auch probiert, das ist exakt das selbe Problem. Ich hab auch meinen Sohn gebeten das ganze mal auf seinem PC zu machen, der hat aber genau das selbe Problem. Er nutzt auch Ubuntu auf seinem Intel PC.
Ich würde meinen das du noch irgendwas zusätzlich installiert hast oder eine andere ESPHOME Version nutz damit das funktioniert.

syssi · 2023-05-09T06:30:38Z

I will spin up a ubuntu 18.04 machine and give it a try. Don't give up! You are almost there!

syssi · 2023-05-09T06:35:27Z

The most recent ESPHome release requires Python >=3.9. Please use Ubuntu 22 and try again.

moscito1010 · 2023-05-09T10:31:34Z

ok, i switched to version 22. Now it's working.
My ESP hardware is az-delivery-devkit-v4 and esp32cam.
ESP32CAM doesn't want to work that well but that's no big deal, I have a couple of the az-delivery-devkit-v4.

Now comes task 2 :-)
How can I connect 2 NEEYś or more to one ESP. I have a total of 5 LFP 16S battery packs.
The ESP should be fine with more than one connection, with another esp32 I connected 5 BLE heating valves, that works great.

syssi · 2023-05-09T10:52:46Z

Do you know this discussion? #310 (comment)

The ESP32 supports up to 3 simultaneous BLE client connections.

moscito1010 · 2023-05-09T11:26:17Z

I read it but don't really believe it.
I have 5 eq3 BLE heater valves that I connected to an ESP32. This has been working for 2 years without any problems.
Here is the link to the project
https://github.com/softypit/esp32_mqtt_eq3

Here my screenshot

syssi · 2023-05-09T12:15:12Z

Hmm... I'm talking about this limitation: https://esphome.io/components/ble_client.html#ble-client

I guess the esp32_mqtt_eq3 project doesn't maintain simultaneous BLE connections. Receiving passive advertisements doesn't does not count here either. May be you can talk sequentially to all devices using a single ESP32.

moscito1010 · 2023-05-09T21:31:39Z

ok, this is probably sufficient for a heating valve.
I took the multi ble codes from you and applied them to the remaining sections according to this scheme. This also works so far, I just don't understand the "interval" section.
I have to specify mqtt directly. when i refer to the secrets.yaml there is an error message from esphome.
man I hope I'm not annoying but this original app is just a horror and it can't do anything. Your ESP solution is just too good

Here is the result of my "copying"

Could you rephrase your last question? What's the detail you are trying to improve? If you want to reduce the amount of traffic passed to the MQTT server you should use the throttle option.

Oh, I got it. I will provide a proper interval section later the day. The interval key accepts time intervals only like 10min or 3h. The ${deivce0} variable/substitution is wrong here. As next step the two retrieve settings buttons must get a unique identifier.

I had the same problem, and disable the
api:
Section solves it, now I see values for 2 Neey in MQ

moscito1010 · 2023-05-16T16:52:04Z

the just api: commented out?

#api:
?

2 things struck me.
I don't need to press boot button to flash, but only when I flash the yaml file for 2 BMS. If I use the "single" script I have to press the button.
You cannot change the battery type in Homeassistant.

physi · 2023-05-17T12:26:13Z

Yes,
# api:

, but the you got no homeassistant "things" .
But that was unstable too, the esp lost contact to both neey this night and does not report anything anymore. Before I had only 1 neey and all worked perfectly good.
So I will invest another esp for each neey, that can than also monitor the temperature of each block.

Or if you get it stable up and running, pleas share your code :-)

syssi · 2023-05-17T13:08:48Z

api enabled or not shouldnt make a difference in general. It looks like a resource issue. Please try to free some resources by removing unimportant/unused components and/or entities.

physi · 2023-05-17T20:22:23Z

tried it with only the voltages from 1-16 on 2 Neeys, does not work, maybe to much to work for one poor ESP :-)
Will use separate Esp for each bank, that works.
Thanks for your nice work on this.

Elektrofix-OL · 2023-11-03T09:04:08Z

I have the same problem and have now gone back to ESPHome version 2023.5.4, but after an indefinite period of time (3 hours or 7 days) I no longer receive any data.
