Mini WiFi controlling CO2

[Boerthyb]

Hello all,

Two weeks ago I installed a Profilux Mini WiFI and LEDControl4 V2 on my ADA 60P freshwater aquascape. In the past I already automated as much as possible (heating, cooling, lighting, CO₂, water level during holidays and dosing fertilizer) to give me more stability and less repetitive daily tasks. But I used all kinds of separate systems, the profilux Mini WiFi is the controller I was waiting for, the app is really convenient and I'm very happy with the system.

I never used to measure my pH but because the Mini came with a pH probe (I purchased the set) I decided to put it in the tank and see what my pH did during the day and week. This already gave me a lot of insight and I'm thinking about using the pH reading to control the CO₂ supply. But then I noticed that the nocturnal change is 1 pH maximum but currently my pH rises a bit more when the CO₂ is switched off. This brings me to the following questions:

• The CO₂ is on from 13:00 till 20:00, during this time I would like to control the pH to a setpoint. At 20:00 the CO₂ shuts of and should not turn on again even when the pH raises more than 1 from the setpoint. Is there a way to do this with the Mini? I know it can be done on the Profilux 4 with programmable logic but this is not available on the Mini (will it be in the future?)

• A few days ago I had an issue with my surface skimmer which caused some scum on the surface which in turn cause the pH to drop too low due to a lower gas exchange at the surface. I saw the pH drop while at work and was able to switch of the CO₂ supply. Is there a way to switch off a socket (CO₂ solenoid) when the pH is below a certain setpoint even when the socket is controlled with a timer? This is of course not necessary when my first question is possible.

• I would like to know what kind of software updates are planned for the Mini WiFi (charts, programmable logic etc.)? I understand the Mini WiFi is a simpler controller than the P4 but it would be nice to know what is on the agenda for the Mini Wifi and what is reserved for the P4. The hardware (connections) limitations are of course clear.

Again, I'm really happy with the controller but a solution for the above would make it perfect.

Thanks in advance for any effort answering my questions.

Best regards,

Maarten
