Today I removed a denkovi input module, to make way for the machinon.
Because the denkovi inputmodule suffers of lag while switching, it had to go.
I will be keeping 1 denkovi input module for stuff that doesnt need fast switching (temp sensors, watersensor,….)
I also removed a couple of relays that had a coil on 220V and switched them for electronic relays that work with a universal voltage. eltako er12-200-uc
these relays are safer, because they dont heat up when used. They aslo use a microcontroller to cut off the current to the coil after they switched.
But before mounting the machinon I installed a temp sensor in it. So that I can read out the temp of it.
(afterwards the creator of machinon told I could have used the internal temp sensor of the pi. I didn’t know a pi had a temp sensor 🙂 )
Then I installed the machinon, and connected al the wires again.
I choose to connect al the com ports of the inputs to the GND and +12V to all the inputs.
I used a separate 12VDC power supply to power the relays.
Then after dubbelchecking I switched everything on and crossed my fingers.
Everything booted up 🙂
