Hello, I currently have a Allen Bradley micro 820 panel performing a 4-20ma output for distinct hourly and daily values. I would like to create a new control panel using nodemcu and arduino ide to output a 4-20ma signal that can be changed via a secure webpage over WiFi . The webpage needs to allow the user to pick a day of the week, then each hour of the day, and input a 4-20 value. That input from the webpage will change the output of the nodemcu to drive a pump via vfd. I already have the vfd portion functional. I also want to control a 3 way valve (flush valve)via a signal from controller that will send a signal based on the start time and duration selected by the user on that webpage. This 5v signal(I’m guessing ) will operate a relay to actuate the valve(24v ac possibly). I may want multiple activations of this valve per day. I also want to receive a 4-20 signal from a tank level indicator and display that to the same webpage that shows a picture of a tank with a color that changes as the level changes. I have a nodemcu, a rtc, and the arduino ide installed. Thank you John

I have a good experience in creation of the web-based remote controls for ESP-based boards. Unfortunately, NodeMCU has not enough CPU power to provide a true HTTPS web-server, so your security requirements need a discussion. Please feel free contact me in chat for it. I work with Arduino since 2010, with NodeMCU since 2015, and have more than 20 years of experience in electronics and programming.

Hello, I have a question about your project: Where do you want the web page to be served from? from the NodeMcu or from a local/cloud web server. I look forward to your reply. Thanks.
