Dipped sensor testing continues

Both the urethane and acrylic dips are holding up nicely. The urethane is currently where I’m steering as it’s more flexible and applies thicket even though it takes a lot longer to cure.

This is in salt water, I'm assuming? What temp? My only concern with room temp vs 78-80F is the possibility of leaching.

Salt water, but at room temp.

dmolavi · Jan 6, 2019

I'd just be cautious about long term exposure in a saltwater environment with higher than normal temps. I'm guessing both will be OK, but I would think the acrylic would be 'more reef safe', since it's a fairly common polymer used in our equipment already.

@Ranjib - is there a way to get a dummy UI up and running on apache or something similar so I can work on that 'offline' from the main controller?

You dont need apache or anything. reef-pi is a standalone http server. You can run it in dev_mode (where all device communications are faked) in your laptop. Thats how we develop it (in macbook or windows). If you are trying to run reef-pi in laptop or other non raspberry pi environment then just follow the development environment setup guide.

@Ranjib Just wondering where you are at with support for Roberto's ph board.
Also would something like this work with the board? I know it's cheap and probably won't last to long but I'm thinking it will work just fine for testing and be replaced with something better after I make sure everything is working as expected.

The super cheap sensors do work, but expect a lot more drift over time. They also aren't well sealed.

You get what you pay for, usually unless it's a deal

I get this error when running the 'make' command, after 'make install':

I got rid of the Sprintf and passed in just i.Pin, channel and o.Pin and it worked...

I'm in...dev_mode is enabled in the configuration section, but I can't add dummy outlets, etc. Is there a way to spoof that data?

@Ranjib is in the middle of swapping types in the HAL layer back to pins being just an int (instead of a name). Since reef-Pi doesn’t use any pinning (glide, or new go modules) if all repos aren’t in sync you’ll get issues.

Cool thanks. I just want to make sure everything is working as it should before I drop 75 bucks on an Atlas Scientific probe.

Use the driver_ui branch. https://github.com/reef-pi/reef-pi/tree/driver_ui
I am in the middle of a large scale refactor to introduce driver api/ui. This will allow us to add new hardware drivers via API /UI (they need to be physically connected for work, for sure). We'll use this to support ph board, multiple pca9685, mcp23017 , base board etc. This (broken master) will be for a short duration. It was definitely not intended, but one thing led to another.. and its better done now than later

Always a construction zone - that just means exciting things are happening

Finally some parts has arrived...

@Ranjib is there an example somewhere of adding a new module to reef-pi? I'd like to create one for my smart power strip, but it uses HTTP, and so won't be mapped directly to a GPIO pin.

So, I've been looking to replace my controller for my Jebao-DCP 15,000 with something RPI driven and was looking at this as a option for the controller. I was wondering if someone with more hardware chops could take a look at tell me if it'll work.

dmolavi · Jan 8, 2019

@Ranjib and @theatrus - thanks for the driver_ui pointer. I'll update my local repo tonight and tinker.

WRT the ATO controller - since I'm only going to read the 'on/off' from the Tunze to monitor usage, my input will be whatever GPIO has that signal, but the 'equipment' won't exist. I am thinking about having an LED just to give it something to connect to in the 'ATO' tab. Is this a viable option?

Correction, the DCP is a brushless motor. So, maybe something like this?
