For the Dutch version, look on my website
https://www.huizebruin.nl/shop
At this moment we only ship to : The Netherlands and BelgiΓ«
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. #57
Before update of the S0tool u should use, and above
Program | version |
---|---|
Home Assistant | v 2024.6.0 |
ESPHome | v 2024.6.0 |
Wi-fi : IEEE 802.11 b/g/n 2.4GHz
Software update information at releases here on Github.
Put the sensors ad your π Look what you need te have te use it.
- 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.
- 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
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.
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.

- 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.
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
- Install Home Assistant & Esphome .
- Connect the wemos d1 mini to a USB charger.
- Go to ssid:
S0tool
- Go to
192.168.4.1
. - Put the correct SSID and Password in the fields
- Wait until it is ready, and then it will indicate the address where it can be found (put it in your router)
- Go to your Home Assistant installation, it will report that a new device has been connected. And add this.
- If all goes well, the print will connect to Github to download the latest version, and thereby also add it to Esphome
- 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) - 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
- 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).

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