I’d just changed the spark 3 with a spark 4 for my brewery. It controls SSR for heater / herms and PWM pumps. There are 3 heaters and 3 pumps. Both of the relays are 5V, provided by the Spark itself. The 3 SSR for PWM heaters are plugged to 3 GPIO modules and the fourth is dedicated to one pump relay. Every thing work very well for the heaters SSR and for the first pump. The 5v relay for the 2 others pumps are controlled by the one-wire SSR expansion board. One relay at pin A and one at pin B.
When I build the block control, once I click on “ON” for the one-wire SSR expansion board, pump is activated (I can measure 5V). But, once I click on “OFF”, the system does not commute to OFF (there is the spiral on “OFF”, the system trying to switch on “OFF” without success. It is the same problem either with Pin A and Pin B.
I’d tried reboot etc, obviously I’d controlled if wires were ok… Nothing better happens…
Some questions : 1. is the Spark 4 and the one-wire SSR expansion board are compatible ?
2. Is it just a update problem (I did not update the system).
3. Something missed ?
4. The best way would be the addition of a second GPIO module for the two pumps plugged to the one-wire SSR E.B. but I would prefer to find a mitigation before
Thanks a lot for your help !
