Okay...I admit this is over the top. 99% of you will think it a crazy scheme.
For the 1% that understand...I want to share a project I am working on.
If you camp with Full HookUps...
If you stay more than a few days...
If you own a coach that has the wet bay located under the Full Wall Slide
If you hate climbing under the FWS to access the valves during your stay
I have just the project for you... Especially, if you have WiFi router and Amazon Echo Dot or other Alexa device.
Yes...You too could ask Alexa to open or close either tank valve from the convenience of your living room. Or use a Wireless RF remote/ or Smartphone App to do the same.
How it works...
To keep the cost under control, and the system simplistic...I used the following components...
3" Barker Auto Drain Valve. PN 24130
1 1/2" Barker Auto Drain Valve. PN 24140
Sonoff 4Ch Pro R2 (must get the Pro Revision 2)
Barrel keyed On-Off Master Switch ( for disarming when NOT connected to sewer)
4PDT On-0ff-On toggle switch
Sonoff 433Mhz Wireless Smart Remote Controller (if desired)
Philmore Right Andle DC Power Plug - 2.5mm ID, 5.5mm OD. (TC250 for power to Sonoff)
Wire as needed...
I have the Sonoff 4ch R2 wired to 12v Non-Continuous Power from behind Cord Reel.
I have the switched 12v power to the two Barker Switches...and the four N.O. terminals on relays R1-R4. The Sonoff is set to Inching Mode...and I have the time interval set to 7 seconds...I may shorten that if it's not needed.(S1 to 1, K5 to 0000, K6 to 1001)
The Green and Brown wires from the Barker Auto Valves go to the Common Pole on the 4PDT switch...you'll have two pairs. The Green and Brown from the Barker control switch go to one switch position...and the common terminal on R1,R2 and R3, R4 go to the other switch position. This allows you to select valve operation between the Sonoff device...or the included Barker control switches. Lastly, the N.C. position on all four Sonoff relays are wired to 12vdc - (ground)
The Sonoff includes instructions for downloading the Smartphone eWeLink App...and connecting to your wireless network. If desired...you can also download the Alexa eWeLink SKILL...to train your Alexa device to open and close the valves.
Well...this is a fun little project. The Barker Auto Drain valves piggyback onto your existing Valterra dump valves...so other than removing two screws to mount the plate...nothing else is required ( they do recommend dumping your tanks before mounting). No more running out in the pouring rain to dump gray or opening gray to do laundry. I'll just make double sure the sewer hose it screwed into the ground connection...and ask "Alexa" to do it for me.
