Dutch version

For the Dutch version look on my website

How to order the S0tool ?

https://www.huizebruin.nl/shop At this moment we only ship to : The Netherlands and België

If u cannot buy it u can make it on your own.

You need a couple of thinks
and place a resistor between the D2 and 5V.

Wemos D1 mini ep8266 Aliexpres or Amazon or dutch webshop Opencircuit

Npn Sensor Aliexpres or Amazon or dutch webshop Opencircuit

10K resistor Aliexpres or Amazon or dutch webshop Opencircuit

And a usb cable and minimal a usb power adapter with 5v and 1A

Will it work with my meter check it out here. https://github.com/huizebruin/s0tool/discussions/57

Before update of the S0tool u should use, and above

Program	version
Home Assistant	v2024.1.0
ESPHome	v2024.02.0

Information:

Wi-fi : IEEE 802.11 b/g/n 2.4GHz

Software update information at releases here on Github.

Hardware

Put the sensors ad your 🛒 Look what you need te have te use it.

5V Power and cable

• Minimal a 5v 1A Bol.com
• usb kabel Bol.com or opencircuit.nl

Or a 5v 2.5A with cable Opencircuit.nl or at Bol.com.

For the water counter

• a NPN sensor - Aliexpress or Aliexpress or Aliexpress or in Nederland at Opencircuit.nl
• (use npn sensor for 5V not that one thats higher than 6V !!)
  I am using the LJ18A3-8-Z/BX-5V
  
  

NPN sensor to the S0tool

Cyble sensor V2 to the S0tool

Here u must add a 10K Ohm resistor between the GND and D2

Soon also a sensor for Elster V100 kogelvorm meter for the S0tool at my shop.

For More information about the S0tool look at my Website.

Watermeter to energy dashboard.

From Home Assistant version 2022.11.X it is possible to add the water meter to the energy dashboard with the S0tool from version v22.10.20.

For keeping track of solar panels or heat pump etc.

• 45A kWh meter with 1000 pulses at kWh Bol.com
• 40A kWh meter with 2000 pulses at kWh Bol.com
  
• 32A kWh meter with 2000 pulses at kWh Amazon
• 40A kWh meter with 1000 pulses at kWh Amazon

2000 pulses per kWh are given. This means that each plus has a value of 1/2000 = 0.0005 kWh 1000 pulses per kWh are given. This means that each plus has a value of 1/1000 = 0.001 kWh

2000 imp/kWh : gives 2,000 impulses per kWh. is therefore more accurate to do a measurement than the 1000 imp/KWh The more energy you consume or supply back, the faster it will switch.

The s0 connection

How to put it to your setup

---

Installation:

First you must have installed the CH340 drivers for the wemos d1 to communicate to your pc / laptop .

Go to this link to install the drivers ch340. https://sparks.gogo.co.nz/ch340.html

06/05/2022:
Now also possible to flash the s0tool directly via the browser.
Only possible with a chrome or edge and opera browser.
Connect the s0tool to your PC/laptop with a USB cable and start the procedure. https://s0tool.nl

1. Install Home Assistant & Esphome .
2. Connect the wemos d1 mini to a USB charger.
3. Go to ssid: S0tool
4. Go to 192.168.4.1.
5. Put the correct SSID and Password in the fields
6. Wait until it is ready, and then it will indicate the address where it can be found (put it in your router)
7. Go to your Home Assistant installation, it will report that a new device has been connected. And add this.
8. If all goes well, the print will connect to Github to download the latest version, and thereby also add it to Esphome
9. Create a folder in your config folder via explorer and name it utility_meter and put another text file in it and rename it to utility.yaml, and add the code below. And save it (or download it from this repro) and put it in that folder. (Code that is under 10)
10. Add the following code to your configuration.yaml
utility_meter: !include utility_meter/utility.yaml

#utility_meter:
### watermeter  S0 meter
  waterverbruik_kwartier:
    source: sensor.watermeter_totaal
    cycle: quarter-hourly
  waterverbruik_per_uur:
    source: sensor.watermeter_totaal
    cycle: hourly
enz...

Those in the file are in the folder utility_meter/utility.yaml

12. Optionally to see if there are new updates, you can create the following Line in your configuration.yaml:
    

homeassistant:
  packages: !include_dir_merge_named packages/

And make a folder in youre comfig map on Home Asstant packages and make there a file like s0tool.yaml and ad there the code from the file from the package map on the s0tool github (or you copy the package dutch or English file from the package folder and put it all in your own configuration).

#sensor: # get away if this is your first sensor
  - platform: rest
    resource: https://api.github.com/repos/huizebruin/s0tool/releases/latest
    name: s0tool_version_github
    unique_id: s0tool_github_version
    value_template: '{{ value_json.tag_name }}'
    scan_interval: 3600

  template:
      - binary_sensor:
          - name: "s0Tool update online"
            unique_id: s0tool_up_to_date
            state: >
              {% set a = states('sensor.s0tool_versie_github') %}
              {% set b = states('sensor.s0tool_versie') %}
              {{ version(a) > version(b) }}
            device_class: update

13. Restart Home Assistant one more time to add everything to your Lovelace screen.

14. Add this card to automatically get an update on your dashboard, so you know if you are using the latest version.

type: conditional
conditions:
  - entity: sensor.s0tool_up_to_date
    state_not: 'True'
card:
  type: markdown
  content: The s0tool is not up to date with the GitHub version.

Blueprint for update notifications.

With this you can create an automation that will notify you when a new version is online on Github. You must have added all the above sensors.

---

Adjusting the meter reading

To adjust the water meter position.
To adjust your kWh meter reading
Or this option and then search for the right meter and then adjust,
here you can update all meter readings

---

Update function

This can be done by the ESPHome dashboard by now.

Have fun with this tool.
Any additions / improvements
may be made via Pull requests be supplemented.
Or via issues requested or added.

USB Serial Drivers

If the serial port is not showing up, your computer might be missing the drivers for the USB serial chip used in your ESP device. These drivers work for most ESP devices:

• CP2102 (square chip): driver
• CH341: driver
• CH340: driver
