Test Solar PV Monitoring Dashboards Using an Open-Source Renogy BT-1 Simulator

Renogy BT-1 telemetry provides useful information for monitoring the condition and performance of a solar photovoltaic system. It can report key values such as PV voltage, current, power generation, battery status, controller temperature, charging activity, and load consumption. These data are important for building dashboards, alerts, databases, and automation systems.

However, developing and testing such a monitoring system normally requires access to real Renogy hardware, including a compatible charge controller and BT-1 Bluetooth module. This can make early development difficult, especially when developers need to reproduce specific conditions such as low battery voltage, peak sunlight, nighttime discharge, or controller inactivity.

My latest open-source project, Renogy BT-1 Telemetry Simulator, removes this hardware requirement.

Application Screenshot

The Renogy BT-1 Telemetry Simulator addresses this problem by generating realistic sample telemetry and sending it as JSON to an HTTP or HTTPS endpoint without requiring physical solar equipment.

The simulator imitates telemetry commonly produced by a Renogy BT-1 module connected to a Renogy Rover MPPT charge controller.

You can manually configure values such as:

  • Solar PV voltage, current, power, and generated energy
  • Battery percentage, voltage, current, temperature, and battery type
  • Controller temperature and charging status
  • Load voltage, current, power, and energy consumption
  • Controller model, device ID, and BT-1 identifier

The application can also calculate PV and load power automatically.

Renogy BT-1 Telemetry Simulator Use Cases

The simulator is useful for testing the Solar PV under various situations:

  • Peak Sunshine
  • Nighttime operations
  • Low battery conditions
  • Heavy loads / light loads

Application Features

  • One-off HTTP Post transmission
  • Periodic transmission at a configurable interval
  • A default two-minute sending interval
  • Live JSON payload preview
  • Transmission logs with HTTP status, response, errors, and request duration

This is useful for testing local development servers, webhooks, staging systems, database storage, monitoring dashboards, and automated alerts before installing physical solar hardware.

Requirements

The application uses WPF and .NET 8, so it runs on Windows 10 or Windows 11. Developers can build it using Visual Studio 2022 or the standard dotnet command-line tools.

The current HTTP client accepts self-signed HTTPS certificates for local testing. This behaviour should not be treated as secure certificate validation for production systems.

Download the Source Code

Renogy BT-1 Telemetry Simulator is available on GitHub:

github.com/mypapit/renogybt1simulator

The project is released under the GNU General Public License version 3, allowing users to study, modify, and redistribute the source code according to the GPL terms.

This project is an independent simulator and is not an official Renogy product.

How to build and use telegram-cli client for Linux

You can actually send Telegram message from command-line interface / bash in Linux using an unofficial “telegram-cli“ client by Vitali Valtman (vysheng)

Obtaining and Compiling telegram-cli

But first, before sending telegram messages, you need to build the client. You may start by installing its dependencies

 sudo git apt-get install libreadline-dev libconfig-dev libssl-dev lua5.2 liblua5.2-dev libevent-dev libjansson-dev libpython-dev make

Then, you can get the latest telegram-cli client from vysheng GitHub

 git clone --recursive https://github.com/vysheng/tg.git && cd tg

Afterwards, you may configure ‘telegram-cli’ and compile it

./configure
make

Alternative Download
Alternatively, you can download Telegram source code from my server:

  1. https://mypapit.net/pub/telegram-cli/tg.tar.bz2
  2. https://mypapit.net/pub/telegram-cli/tg.tar.xz

 

Running telegram-cli

After finished compiling telegram-cli, you may try and start using telegram.

bin/telegram-cli -k tg-server.pub

For first time use, you may need to key in the authorization code, the code will be sent to your mobile device to allow ‘telegram-cli’ to log as your username.

bin/telegram-cli -u  -k tg-server.pub

In my experience you may need to replace the +[country_code] phone-number with ’00’. so if your phone number includes country code is +60123456789, then you must replace it with 0060123456789 (however, your mileage may vary.

bin/telegram-cli -u 00123456789 -k tg-server.pub

Once the authorization CODE has been entered, you are free to use telegram. Telegram use the concept of ‘peer’ (contact) to send messages instead of phone number. So in order to get a list of your peer, you need to run “contact_list” command.

telegram-cli-contact-list

> contact_list
John_T_Doe
Jane_doe_2
Warrick_Brown
Mark_Nelson

To send message to a peer/contact (for example to Warrick Brown), just type

> msg Warrick_Brown "wassup, dude? want to hang out today?"

To quit, you can type

#telegram-client
> safe_quit

NOTE: IF YOU FAIL TO COMPILE TELEGRAM FROM GITHUB
If you find it difficult or failed to compile telegram-cli from GitHub, then you can download this telegram-cli source code from my server which is tested to compile under Raspbian Jessie, Debian Jessie, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.

Alternative Telegram source code:

  1. https://mypapit.net/pub/telegram-cli/tg.tar.bz2
  2. https://mypapit.net/pub/telegram-cli/tg.tar.xz
