Control/Switch panel

[indicaxsativa]

V.2 of the control panel I am adapting as I go.

 

The power meter with the blue display has made keeping an eye on useage simpler with the 50% hike due in a month or so.

Need to tidy up the cabling a bit in the lower box as I'll be adding another contactor or two for the fans.

 

The Arduino / Pi will be in the top box on dinrail mounts and use a ribbon cable so that a touchscreen can be mounted into the lid.

 

Opto isolators to separate the AC in the lower box.

 

Then I can monitor everything remotely.

 

I make a plan God laughs ...

Spotted this on a carboot stall.

 

From what I have gathered its called Randa.

 

Connects via Gpio on a Rpi3.

 

Hoping to get it to work on Rpi4.

 

Pins are the same but might be some hardware / os things need to understand first.

 

But it will be controlling pumps,light and temperature soon hopefully.

For anyone interested in this Arduino based hat for the Pi here is a link.

 

Not sure if these are still produced but might be lucky and find one some place.

It seems the Gpio pins are level shifted within the Randa board which is handy.

 

Obviously some functions like the rtc and switches to power up down/reset both boards independently of each other may not work on the Pi4 but its going to be fun finding out.
