Ratings and Reviews

It works, clunky interface and junky in-app bait


It does work but the interface is not very intuitive and the icons are refresh icons not connect icons. Needs work. Not worth a subscription app.
Should have a server built in.

They don't say much about their product


I will have to rate on the high side since they don't say what their product will do and it does about that. A hint, don't forget to offset your number by one. Only one number will be read at a time. This routine will send out the basic modbus commands. There is Onother product that will do more of what one actually wants. To request help, you have to join their online support and sign away your life's history away along with all your friends and acquaintances. I think this might be a front to force tekkies to join social media. The software is lean, clean and after much guessing does function as stated.

Developer Response

No more guessing needed, the latest version comes with a video:
No, this is not a front to join social media. The support forum is there to ensure answers to questions can be shared with all users.
