Anyone into home automation/smart homes with integration to Alexa, Google Home, Siri, etc.?

Ah you mean the Pro will only serve as the main hub while the Mini will be like a repeater? Then I can connect the Pro directly to my Google Home/my phone?

Not quite. They both serve almost the same purpose, which is to flood the room with IR light to control any device in the room. The only difference is that, the Pro also has RF capabilities in that, aside from IR, it can also blast your whole home with RF to control RF devices in almost an room..

You will only need the Pro if you have RF devices to control. Otherwise, you’ll need the Mini3 in every room where there’s an IR device like A/C you wish to control.

It would have been more challenging to have the bathtub water set to a preset temperature.

The non-variable valve opening shouldn't be an issue. What is needed are a couple of temp sensor that samples the water temp and a controller that turns on/off the cold and/or hot water tap to achieve the preferred temp. Then, it will need a water level or pre-overflow sensor to make sure the water does not go over a certain level. Once the target level and temperature is achieved, the owner receives a notification.... "Your bath is ready, sir." -- in an English, butler-ish accent.

Future thesis writers... here's an idea for you.

Now, if only we have a bathtub. :D

Its an issue for the thesis panelist then bcoz we also control the light remotely to ward of intruders who could think that the house is unattended if theres no light the whole night for several days

With our contraption a user can remotely turn on the light..so its basically an on/off situation

A fully open or fully closed valve operation will be similar to an on/off light switch thats why the panelist specifically requested a variable valve operation (slightly open, half way open, fully open, fully closed valve)

There is a similar implementation of this idea, it is the jacket water temperature of the main engine that propels a ship.

ON/OFF controller won't do for this type of control. Instead, PID (Proportional Integral Derivative) is used. There's a pneumatically​ controlled valve to regulate the flow of the cooling medium and a 3-way valve to recirculate it or discharge it overboard.

A feedback temperature is of course installed to the return line of the jacket water which dictates the position of the 3-way valve.

I believe that it is possible to have this idea implemented in a bathtub.

If you just want to control relays and some C+ knowledge there are DIY Adruino kits you could customize.

I'm having pinlights installed right now for my living room, what's the best product to get them connected to the RM Pro?

This is fun, bouncing ideas with you guys.

By controller, I had the Arduino in mind as the center of the water valve trigger as well as the temp and water level feedback. Though, other modules will still be required for the front-end interface, solenoid drivers, sensors, as well as network connectivity to be able to send out notifications and/or for the user to be able to access the interface remotely through an app. Maybe even an API to integrate with Alexa, IFTTT, etc. I'm thinking of the Raspberry Pi for the interface and IoT integration.

Many homes would have a hot and cold water tap and to adjust the water temp that ends up in the bathtab, the logic just needs the temperature feedback and the preset target temp. It will then open up the respective valve, hot or cold. At a certain level, if the feedback circuit detects that the water in the bathub is too cold for the target temp, it will keep the hot water valve open longer than the cold water valve and vice versa.

I know this should work in theory, just don't know how to get there.... along with where do I put the bathtub.

The greatest difficulty will be where to put the bathtub!

Yes, Arduino should work. I was thinking of the industrial application that I forgot about servo motors that can be controlled through it which is practical to do instead of a pneumatic valve.

Because pneumatic and hydraulics are for larger loads and you will have to supply steady source of compressed fluid/air.

For home use, this will just involve input sensors and instructions to control relays maybe 5V direct output from logic board.
You will need to wire each physical switches to the relay/SCR solid-state-relay just like what the hotels proximity-card access are using or maybe a magnetic contactor to control the power in lieu of the circuit breaker. There are China units along T.Alonzo that sells those proximity access locks with option to security just like what fire & burglary alarms and auto dial emergency numbers.

Same as most remote controlled environments like server rooms have these to control the operation of aircon for 24h rotation, a temperature, smoke/fire and flood sensors that transmits alarm to a monitoring center or a life-support system of your Goldfish that automatically trigger alarm when power is out on the aerator. Even some UPS have alarm output relays to transmit commercial power conditions.

I've succumb again to my weakness, please don't judge me. Tech is my kryptonite.

Even though the Echo Wall Clock is seen by some as a gimmick, it's MY gimmick. And the wife seems to love it to no end. She'll have much use of it in the kitchen.

Even the older generation is trying to catch up with the new technology. Hey goo-goo!
