![]() This allows for less strict command control.Ī special macro, called "FUN" automatically sets the hot tub to full on and the temperature to 98 degrees.Īlexa has been trained through IFTTT to "trigger hottub fun" to turn everything on.Ī new control strategy has been implemented for sleep. The command parser ignores spaces and automatically changes the case to uppercase. This allows fewer buttons and all controls fit on a single screen.Īny other command, including "P1" with no arguments is interpreted as an off. The mobicle buttons are programmed to act as toggles. This responds to string prefixes that are associated with the command and a postfix that corresponds to the action.Ī "P1 T" toggles the pump state. The particle photon has a single function "hottub." Temperature and control system feedback are implemented through mobicle.io. The enclosure is gasketed and much nicer than the original. All wires run through liquid tight compression fittings. The high voltage relays are mounted to the aluminum heatsink in the back of the enclosure. The photon is attached to the outer door with velcro as well as the power supply. ![]() The heater cell in the hot tub retains its mechanical overheat lockout for safety as well. These are features the old system did not have. The two heater sensors can detect a lack of water and also can detect a circulation pump failure when the heater is on. () The screw shield has two thermistor connectors and the pullup resistors for the 10K heater thermistors. Now nicer screw terminal breakouts exist for the particle. This is older hardware I had laying around and not what I would recommend for new builds. The photon is capable of driving the relays adequately directly. They did not have enough power to trigger the opto relays. The level shifters on the shield shield had to be removed and bypassed. The particle photon was attached to a shield shield and then to a screw shield. A 12V output dual voltage input supply was chosen and attached to the outer door. 100A relays were used throughout to keep the temperature down though the complete system should only draw about 50A. Relays were mounted to a 1/8" thick heatsink plate inside the box. Opto 22 style solid state relays were driven directly from the particle photon pins. As a bonus there is a hydraulically operated TV that pops up when one of the zones is activated. ![]() There are quite a lot of things to operate and control in this tub. It has 4 water pumps, an air pump, a 6500W heater and an O3 generator. Window.APP_STATE = JSON.Solid state relays were used to interface the particle photon to the hot tub motors.
