I haven't read that mail. Probably I have skipped it accidentally.
If there is interest in KanbanFlow instead of Trello, I have wrote a vb.net program to check my pomodoro counts every 5 minutes that has been done inside KanbanFlow and email the most recent count (if it has changed from the last time sent) to pomodoro beeminder goal.
The program should be run on a pc, but I am trying (i.e., struggling) to translate the vb.net code into asp.net and running it as a server app in appharbour for free. It seems the asp.net works fine on my local test but there is some weird error when I push it to appharbour. Microsoft Azura was better in receiving the code and compiling without errors, but did not work correctly there inspite the zero error of compiling in Azura. The app was running in the Azura dashboard , but did not send any emails to beeminder. And I don't like Azura since there is no free option there. So most likely I will keep trying with appharbour.
Anyway the vb.net code now works well on my pc for around 1 month now. If there is interest, I will make a new forum post for pomodoro beeminding automatically with KanbanFlow
P.S.: KanbanFlow worked much better for me comparing to trello. Since it has an integrated pomodoro watch and pomodoro statistics which works natively with the kanban tasks. You can get on overview on KF here and here.
By the way, KF has an API but it does not support pomodoro counts. So I had developed my code to open the webpage of my kanban board, automatic login and parse the html and read the pomodoro points in the upper right corner of the page. That was my only way to automate it, but it works perfectly.
Coding is not my profession (hobbyist), do not expect a well designed code, but you can make your changes and enhancements. Maybe you can even use it as a guidance to code a similar code in your own preferred language.
Any KanbanFlow user here who would like using this code?
