Right now, PWM is not in the master branch, so you can look on the pull requests and manually make the sited changes to the files or you can use schrod's patch (though I am not sure how it works) for his version.

I'll give it a try.

This morning, I put up a pull request for a modified version of schrod's PWM automation module. This one allows you to set a starting heater efficiency, then at a designated number of degrees below your target to shift to another frequency. I have tested it on the hardware, but have not actually...

There are options on the configuration page for passwords and usernames, but does anyone know how to actually force a login to the software before using it? I can always get right in. I just set up a stand-alone fermentation controller that runs CPBi and I want to expose it to the Internet so...

Thanks! I was just reading this on the GitHub site. I can't wait to try it out. I may try it with a water boil tonight. So, it will go to a set temp and then kick into the duty cycle? Or will it start with the cycle whenever the kettle is active in automatic mode? Since I don't have it loaded...

Got it ordered. Thanks!

http://www.auberins.com/index.php?main_page=product_info&products_id=444 Is that the one you are using? That certainly looks like a good option.

Yes, but I'm not even sure this is on the roadmap. Since I don't know how to add this in myself, I need some sort of solution until then.

I found this post where the guy is using an SCR. Would this be an option? https://www.youtube.com/watch?v=A-jDnFt402A One like this maybe...

I finally did my first run on my CPB rig last night. I hit one little snag that i don't know a way around. I am using 220V 5500W heaters (like this: http://www.ebrewsupply.com/304-stainless-steel-element-4500w-ulwd-ripple/) to heat the water for the HERMS system and for directly heating the wort...

I'll try to give this a shot tonight. Thanks!

To be clear about the behavior I am seeing: Pi power-up: All relays on the board are in "off" state All loads powered since I have the relays wired to NC to give correct operation using the dashboard CBPI software startup: All relays immediately switched to "on" state No loads...

I will give this a shot this weekend. Update: I tested this solution and it had no appreciable effect other than one of the SSRs (wired to IN5) no longer correctly switches with the relay is tripped.

That might be one reason for using SSRs, but my reasoning is purely that the relay board cannot handle the current that I have on the 220 side to run the heaters. Since the SSRs are driven by the relay board, I have the same issues with them coming on until the CBPi software starts. The...

I can wire the relays so that the load is powered in either the off or on state (NO or NC), but since the default for the RPi is off and the default of CBPi is on, my pumps and heaters are on as soon as I power the RPi until CBPi starts. I have tried the solution earlier in the thread to...

Here is my controller and wiring diagram. No shields at all, SSRs for the heaters and a relay board for the pumps. I can email anyone a PDF or visio of the diagram if they want more detail. As stated earlier, I do have one weird issue where the outlets are on until the software starts which I...

I don't think that 2.1 has any provision for automating pumps/agitators in the steps yet. I believe this is planned for 2.2. For now, I think you have to run those manually (through the buttons on the dashboard).

Can you flip the relays by manually hitting the buttons on the dashboard (or by using a python script)? Are your heaters set to auto (the car icon)? Are you using pin position or GPIO numbers to indicate your GPOI to relay mapping?

There is a schematic of my build on page 32 of this thread. It may not be the most ideal, but it works for me. There are plenty of pictures of completed systems on the CBPi Facebook page.

Any idea what I might have missed? I am hoping to use this rig for the first time this week and I would love to have this solved first.
