Re: Finally hacked up my wireless web-connected timer
Are the mods needed to the layout or the resistor values?

Re: Finally hacked up my wireless web-connected timer
which optoisolators did you use?
Would you mind sharing your raspberry pi zero code?

Re: Finally hacked up my wireless web-connected timer
I tried building the board but I could not get it to work, loading from the SD card was really slow. I changed my approach and used the ESP8266 with the shield relay and used the Blynk app to turn the espresso on. The only problem is that the Blynk app for IOS does not have the eventor widget, only ...

Double Shot - Pin 2 and Pin 7 4. Steam Boiler - Pin 2 and Pin 9 5. Watter - Pin 1 and Pin3 Lights: 1. On/STBY L...

Re: HOWTO: Installing a power-on timer on your S1 (Request)
It is 1 and 11 for the connector. when you look at the control panel, the top row counts as 1,3,5,7,9,11. As such connector pin 11 is the 6th top pin. I hope this makes sense.

I am interested if someone has a needle valve/flow profiling mod on their Spazialle S1 machine.

Re: S1V1 Steam Boiler tripping GFI outlet
I had the same issues a few years ago, right after I bought the S1V2. It was metal shaving in the tube that exited the boiler and was clogging the line causing backflow and created a leak, which in turn tripped the GFI.

Re: Modification Timer, Wifi, manual dose,...
the pinout is the same, however, I attached a 3 relay board and the associated pins for the relay are now GPIO 26 for relay 1, GPIO 20 for relay 2 and GPIO 21 for relay 3. I can remove the default jumpers and add jumper wires to match your program. I'll do that this week and report back to the forum...

Re: Modification Timer, Wifi, manual dose,...
I just bought the raspberry pi 3 B with a 3 relay board. Will the software work for version 3?
