Methods, systems, and devices for providing communications capabilities to equipment of swimming pools and spas
Communications capabilities are supplied to components of pool water recirculation systems, even if the components lack electrical power or supply wires. Capabilities may be furnished by wireless RF devices that connect to existing fittings or ports of the components, for example. The devices are configured to obtain desired information relating to the components (or the water within them) and transmit the information remotely for processing or consideration.
1. A method of determining whether a strainer of a component of a pool- or spa-water circulation system is clogged with debris, comprising:
a. mechanically connecting to the component a first device including a first pressure sensor and a first electronic transmitter;
b. electronically transmitting pressure values obtained by the first pressure sensor to a first location remote from the component; and
c. evaluating the transmitted pressure values to determine whether the strainer of the component is clogged with debris.
2. A method according to claim 1 further comprising conveying the determination to a homeowner, servicer, or manufacturer of the component.
3. A method according to claim 1 in which the component is a pump.
4. A method according to claim 3 further comprising withdrawing power to the pump as a consequence of the evaluation of the transmitted pressure values.
5. A method according to claim 3 in which the evaluation of the transmitted pressure values occurs at the first location.
6. A method according to claim 3 in which the first device is positioned downstream of the strainer and upstream of an impeller of the pump.
7. A method according to claim 6 further comprising mechanically connecting to the pump a second device including a second pressure sensor and a second electronic transmitter.
8. A method according to claim 7 in which the second device is positioned between the impeller and a fluid outlet of the pump.
9. A method according to claim 8 in which the first electronic transmitter is configured to transmit signals wirelessly.
10. A method according to claim 9 in which the second electronic transmitter is configured to transmit signals wirelessly.
11. A method of determining whether a strainer of a pump of a pool- or spa-water circulation system is clogged with debris, the pump also including an impeller and a fluid outlet, the method comprising:
a. mechanically connecting a first device including a first pressure sensor and a first electronic transmitter to the pump downstream of the strainer and upstream of the impeller;
b. mechanically connecting a second device including a second pressure sensor and a second electronic transmitter to the pump downstream of the impeller and upstream of the fluid outlet;
c. electronically transmitting first pressure values obtained by the first pressure sensor to a first location remote from the pump;
d. electronically transmitting second pressure values obtained by the second pressure sensor to the first location; and
e. evaluating the transmitted first and second pressure values to determine whether the strainer of the pump is clogged with debris.
