TeHyBug Bot for Telegram messenger exists already for several years, but not many are using it, probably because they don’t know what it is and how to use it.

First of all, you will need a Telegram messenger you can install from the apple app store on iPhone or google play store on Android.

Then open https://t.me/tehybot or search for TeHyBot in Telegram and start chatting with it. If it doesn’t start chatting with you automatically type /start and submit. After that, you will receive the chat id number.

Copy the chat id and head over to TeHyBug.com profile settings and provide there your telegram chat id.

From now you can use the following commands in your TeHyBot chat:

/humidity – to receive the humidity sensor data

/temperature – to receive the temperature sensor data

/chat_id – to receive the chat id again, in case you forgot it.

/help – to show the full list of available commands

You can also define Telegram alerts for your TeHyBug in the alert settings and TeHyBot will send you alert messages.

I have created a compact and versatile neopixel driver board that has multiple uses, including functioning as a ser2net programmer, data logging environment, and reading UART sensor data.

Both technologies have their advantages and disadvantages, here is a side-by-side comparison of ZigBee vs Wifi sensors for the smart home. For my comparison, I take the TeHyBug Wifi sensor and Aquara ZigBee Sensor which is connected through a HeilBee v4.5 ZigBee stick to my HomeAssistant.

The cc2652p based ZigBee sticks, also known as v4 ZigBee sticks, are currently one of the most popular options in the market. This is because these modules come with a strong signal amplifier and a PCB antenna that allows for transmission distances of up to 700m without the need for an external antenna. Compared to ZigBee sticks based on the cc2531 chip, these modules offer much better performance.

There are various ZigBee v4 sticks available from different manufacturers, which all use the common cc2652p chip and function in a similar way. However, most of these sticks lack wireless network communication capabilities, which can limit their use in certain scenarios. While there are some cc2652p modules with LAN capabilities, there were no ZigBee v4 sticks with ser2net over WIFI support that could be connected to a standard USB phone charger.

To address this limitation, I decided to design a ZigBee stick v4.5 that supports ser2net, which is wireless serial communication, and doesn’t need to be connected to a home automation hub via USB. The TeHyBug ZigBee Stick V4.5 was born from this idea, and it offers users the flexibility to connect the stick wirelessly to their home network without the need for additional hardware or cables.

The TeHyBug ZigBee Stick V4.5 features a built-in WIFI module that supports ser2net communication, allowing users to connect the stick to their home network wirelessly. This means that the stick can be placed anywhere within the range of the WIFI network, providing greater flexibility in terms of placement and usage. Additionally, the stick is compatible with a range of popular ZigBee devices and can be easily integrated into any existing home automation system.

In conclusion, the TeHyBug ZigBee Stick V4.5 is an innovative and flexible solution that offers users greater flexibility in terms of placement and usage. With its support for ser2net over WIFI and compatibility with a range of ZigBee devices, it’s an ideal choice for anyone looking to expand their home automation system.

There are several ways it add a TeHyBug to your HomeAssistant.
1. Embed a public graph to your dashboard.
2. Add it as an MQTT Sensor to your Homeassistant.

Usually, Home Assistant is installed on a Raspberry Pi or similar devices.
If you don’t have an MQTT Brocker, here is the instruction on how to install the MQTT Broker on your PI.

https://randomnerdtutorials.com/how-to-install-mosquitto-broker-on-raspberry-pi/

1. Put your TeHyBug into a configuration mode.
2. open HTTP://192.168.1.1 in your browser (Firefox works best)
3. Configure WIFI Connection by providing your WIFI Credentials.
4. Go to Custom MQTT Configuration and fill the required fields similar to the screenshot below, the MQTT Server should be the IP Address of your MQTT Broker

5. Save, activate the live mode and restart the TeHyBug.
6. Make sure mqtt block in the configuration exists, if not please configure it a your home assistant integration. Open the configuration.yaml file of your home assistant and add a sensor block, if the sensor block exists, just extend it:
   

Example configuration.yaml entry:

sensor:
  - platform: mqtt
    name: "Temperature Test"
    state_topic: "/tehybug/sensor1"
    unit_of_measurement: "°C"
    value_template: "{{ value_json.t }}"
  - platform: mqtt
    name: "Pressure Test"
    state_topic: "/tehybug/sensor1"
    unit_of_measurement: "hPa"
    value_template: "{{ value_json.p }}"

After this, you will be able to add a new sensor entity to your dashboard.

A demo image with a link to scriptable code with detailed instructions.

Requirements

• iOS 14 or higher
• Scriptable version 1.5 (or higher) https://apps.apple.com/de/app/scriptable/id1405459188
• TeHyBug.com as the default data-serving platform for your TeHyBug device. https://tehybug.com/

Here is a short demonstration video of programming a TeHyBug with its software:

Once you connect to the TeHyBug Wifi Network AP and open http://192.168.1.1/ in your browser, you will see the configuration index page.

The first thing you should do is to provide your Wifi Credentials on the “Configure Wifi” page. Nothing special just fill the form with your network name and password.

The next step on TeHyBug 18650 Universal is to select the connected sensor on the “Sensor configuration” page. Here is also nothing special, just select the sensor that you have connected.

Then go to the “Current environment data” page and check if the sensor is delivering data properly.

As next select the desired data serving method, if you don’t know what an MQTT or HTTP POST/GET request is, then you should use the “Default configuration” page and leave other data serving methods untouched.

(For the “Default configuration” you’ll have to create an account at http://tehybug.com )

(If you chose the default configuration please write down the TeHybug key. You will need to provide it at your TeHyBug account.)

On the default configuration page, you’ll have to define the data frequency in minutes. Data frequency is a time interval that defines how often should the TeHyBug measure the sensor data and send it to a remote data server. Lower data frequency means higher power consumption and causes the battery to discharge faster.

Once you click save, the success message will ask you to activate the live mode and start serving data. If you are ready with your configuration, you can click the “activate live mode” link. Optionally you can also activate the live mode from the index page, so you don’t need to do it on the configuration page.

Then you will see the next message to restart your TeHyBug, when you click the restart link, your TeHyBug will close the WIFI Network AP reboot and start serving data.

Done!

Login to your data server and check the TeHyBug Sensor data.

First start guide

Important: You will notice black glue on the front of the ESP8266 ESP-01 module, don’t try to remove it! It protects a thin tiny wire, which enables the power-saving deep sleep mode of the chip.

Warning: TeHyBug is not protected against reverse polarity. Reverse polarity of power source will damage/burn your device. Make sure you connect the power to the screw terminal correctly.

When you connect a power supply (min 3.4V, max 12V, 5V recommended) to your TeHyBug, the blue LED on the ESP-01 module will light up solid, which means that your TeHyBug is in a configuration mode.

If you plan to use a 9V Battery make sure that the real battery voltage is below 10 Volts otherwise it will damage/burn your device.

TeHyBugs with an OLED display are already preconfigured in a „display only mode“ and are ready for use, just connect it to a power supply. If you would like to change the configuration or use some different data serving modes: you can put your TeHyBug into a configuration mode by pressing the RESET „BLACK“ button and shortly after that the MODE „RED“ button, the blue led will blink shortly and light up after 3 seconds solid.

Configuration

1. Open with your computer or mobile phone a list with available Wi-Fi networks, there will be a new Wi-Fi network called TeHyBug_XXXXXX
2. Connect your device to a TeHyBug Wi-Fi network.   
3. After your device is connected to TeHyBug Wi-Fi network, start your web browser and open this address: http://192.168.1.1/

The TeHyBug configuration webpage will open and you will have multiple multiple configuration choices.

You should start first with the Wifi configuration and provide there the Wifi Credentials of your home network.

Once the wifi configuration is saved, continue with the data serving configuration, there are several data serving choices:

Default settings if you are going to use the tehybug.com data server (signup at tehybug.com website and add your TeHyBug into your account) or custom settings where you can define the URL of any other data server.

After everything is set, you can activate the live mode and restart your TeHyBug, it should start serving the environmental data.

How to activate configuration mode manually with buttons on the board?

If you have provided incorrect Wi-Fi credentials in the configuration mode or you would like to change the settings:

Press the RESET „BLACK“ button and shortly after that press the MODE „RED“ button, the blue led will blink shortly and light up (after 3 seconds) solid, after that, you will be able to connect to a TeHyBug Wi-Fi network and change your configuration.

How to activate the live mode manually with buttons?

In case you have put your TeHyBug into a configuration mode by mistake (the blue led lights up solid) and you don’t want to change your previous settings, you can activate the live mode by pressing the RESET „BLACK“ button, and shortly after that press the MODE „RED“ button (the same way you put your TeHyBug from a live mode to a configuration mode), the blue LED will blink short (it means that you TeHyBug is in live mode, connecting to the configured Wi-Fi network and is serving the data).

Your TeHyBug has an additional Micro USB connector, so you can power it directly from a USB power supply. DO NOT use a battery and a USB power supply at the same time, it will damage your devices.
