I was curious with VOLTTRON agent development if an agent could be used to expose discoverable BACnet points to a building automation system.

For example, BAC0 that also uses bacpypes under the hood like VOLTTRON I can create a really simple BACnet app (shown below) and discover my BAC0 app (and points) via BACnet to the building automation system.

I have an odd use case not to control or acquire data (I think typical VOLTTRON use case) but only to "expose" a few read only AV BACnet points (integers that represent the count of people in particular HVAC zones from some other system counting people) to the building automation system.

Sorry another vague question but would there be any examples to look at if anyone has done this with an agent development? I'm curious if some BAC0 code could just run in an agent if the BACnet proxy has not been installed via typical VOLTTON development. Any tips/help greatly appreciated.

I have this digital dial indicator : Helios-Preisser Digimet 1722-502". It comes with a capacity to output its reading over a USB serial cable. The USB cable is a special 4 pin connector on the end that plugs into the calipers and a normal USB on the other end.

Although the device comes with special software, I am trying to write a basic python library to communicate with it. Below is the snippet of the manuel which explains the data communication protocol

I am using the python Serial library and have managed to get some communication going with it. Here's what I have so far

I am building an admin tool app for our system. I want to record every action made by every user.

I have question My code works but i dont understand what is $x[1] and $y[1] in function I tryed $x[0], $x[1], $x[2], $y[0], $y[1], $y[2] and dont get the logical output ? Where i am wrong to understand ? Please if someone can help me ?

I am using gekko to solve a system of equations. As an intermediate step I am using an intermediate that plugs the MV temperature into the following function:

Situation: I have a weather GUI made in tkinter. It gets data from an api and and displays it on a tkinter label. One of the functions 'format_alerts' parses json data from the api. Because the way the data is formatted I'm having trouble parsing it for what I need.

Problem: I came up with a really weird way of parsing the data. The json uses '...' and 'astrix' to separate values in a string (inside a dictionary). I use .replace('\n', ' ') to get rid of newlines. I use .replace('astrix', '@') and .replace('...', '@' to find the split points. Then use .split('@') then reference the list index number. However sometimes the json uses '...' randomly so I end up messing up the indexing. I know regex is a better way to do this but for the life of me I can't get a three part regex search to work.

My present code looks like:

Hello I have a problem connecting to postgres with the elixir, I tried the following on docker-compose:

I used environment variables, but it wasn’t so I tried putting string in dev.exs, but even then it still rejects the connection.

I tested my postgres and it works normally and has the database created all right log:

postgres-db | 2021-02-23 22:46:30.410 UTC [1] LOG: database system is ready to accept connections

I am trying to create a simple bash script that takes paths to directories as input and plugs them into an scp command. The scp command looks like this:

I am trying to set up an ESP8266 ESP-01 WiFi Module to post a tweet when sent some sensor data. For now, I'm just testing out the POST > Webhooks > IFTTT > Twitter workflow.

I get a response code of -1 (negative one) in the serial monitor when I run the below code. A few notes:

• I am using a USB programmer that the ESP-01 plugs in to to do all this (called ESP-01S USB to ESP8266 ESP-01S Wireless Wifi Adapter Module Wi-Fi CH340G 4.5-5.5V, 115200 Baud Rate, if you wanna see the specific one), so not running the ESP-01 through like an arduino uno or anything, if that somehow matters
• I know the sketch upload is working and the script is running fine, as the ESP-01 reports its connection to my network and my Wifi network reports a connection to the device
• I know the trigger url works because it posts the tweet when I run it from within IFTTT Webhooks service and when I "curl" it from terminal
• I tried to use GET instead, but it had its own issues, plus I am going to want to send sensor values, so want POST to work
• I've tried both the urlencoded and json versions below, same result. Would prefer the uncommented json version, as am familiar with that
• I am a total POST beginner, so am probably missing something stupid
• It says timerDelay is 10 seconds but is set to 20. That's because I thought maybe the POST was just timing out? So I gave it more time
• I also rolled back the ESP8266 library on Arduino IDE, per some Arduino forum rec. No help.
• I tried flashing the ESP-01 with NodeMCU one time, didn't do anything. But not sure if that has to be done before every new sketch upload?

Here's my code. The trigger is real, so feel free to put in your own SECRET_KEY and post the app. Posts to @KreiderPlants on Twitter.
