Josh's thread on ESP builts and 3D cases

[Joshua]

Hey folks,

I'm converting my home IOT system from zwave to the RFM and ESP nodes in this forum. I'll share the construction of each node along with the 3d design files. Here's the list of nodes I plan to post.

RFM Devices can be found in the OpenHAB & RFM69-based Arduino board here
- Gateway
- Door
- Motion/Temperature/Humidity
- Garage
- Current
- LED controller

ESP Devices
- Dimmer
- Relay switches

decor switch housing for ESP relay....

I designed this to replace a Honeywell timer switch that quit working.

This node is programed with ESPEasy*

*Always change the WPA AP Mode Key: to a high entropy password. The ESP will setup its own SSID when it cannot connect to your network. This could allow someone, in the know, to connect to the ESP and pull you network connection information (including your password)_

Here are the devices enabled:

Push button

1st GPIO: GPIO-0 (D3)
Pull UP: enabled
Switch Type: Switch
Switch Button Type: Push Button Active High

Relay

1st GPIO: GPIO-5 (D1)
Pull UP: enabled
Switch Type: Switch
Switch Button Type: Normal Switch

Rule: (Enable Rules via Tools - Advanced - Rules (checkbox))

on button#switch do
if [button#switch]=1
gpio,5,1
else
gpio,5,0
endif
endon

Thanks, Joshua, for adding a thread in the ESP82xx board. We needed new activity here.

Perhaps you could add a wiring diagram for this project.

- 120V DUPLEX RECEPTACLE WALL OUTLET PLUG
- R3-11 Fuse Holder Socket Used For 5mm x 20mm Fuse Chassis Mount 10A 250V US
- 5x20mm Quick Blow Glass Tube Fuse Assorted Kit Fast-blow Fuse 2 amp for this build
- Hubbell 15-Amp 125-Volt White 2-Wire Plug  |  I trimmed off the housing of this plug as it will be installed in my 3D printed housing

- I get the wire from an old computer power cord

- I'm not implementing a potentiometer or momentary switch for the "virtual switch". This option didn't work well for me.

papa: Thanks, Joshua. Very complete addition to our projects & again we needed more in the ESP82xx board.

Joshua: "openHAB 1 Items | I haven't tested with openHAB 2 yet"

papa: perhaps you have seen my recent updates on using OpenHAB 2.5.0.M1, the MQTT 2.xx Binding, & the Embedded MQTT broker.

It works well while one must tolerate some tedious clicking & field-filling until PaperUI gets upgraded to the next generation.

You might get some hints in this thread.

I wouldn't recommend this, you could create an insurance issue if it causes a fire. It's also not for amateurs, and is illegal in many parts of the world.

Here is a prebuilt solution:

www.amazon.com/gp/product/B07K67D43J/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

you can get it for $15 on sale, and it can take ESPeasy or Tasmota without even opening it up. Tuyaconvert works perfect with it.

But that ARMtronix board is cool too - shame it's kinda pricy for what it is.

Another FTDI Clip

www.thingiverse.com/thing:3797819

I would just assume purchase one of these. However, I can't find one quite like the clip provided by easySensors CP2102 with Pogo clip for 2.54 pitch FTDI headers located here. They have been sold   out for quite some time.

After you print it out, you'll need to drill out the holes for the pogo pins. Additionally, I stretched out the spring shown on the pictures. I've included the dimensions of a larger spring on the parts list below that should work better. Finally, the rubber band will help with tension.

Here's the parts list.
- 6 - P75-E2 Spring Test Probe Pogo Pin 1.3 mm Conical Head 1.0mm (I recommend having spares)
- 9mm Outer Diameter 1.2mm Wire Dia 30mm Long Compression Spring (I'm guessing here)
- M5 machine screw and nut (a least 25mm in length)
- Female Header 1x40 2.54mm (trimmed down to solder onto ends of the pogo pins)
- hot glue to hold the header/pogo pins in place

        Convert a Decora Form Factor Dimmer/Switch

            to a Dimmable/Switchable ECOplug

The limitations of the Armtronix dimmers have become too much of a pain and the above comment from jimkernsjr led me to develop this project. You should be able to easily convert an Decora switch or dimmer to a lamp plug with this box.

The 3d printer file for the case is here www.thingiverse.com/thing:3822260

I loaded tasmota onto the dimmer referencing this wiki github.com/arendst/Sonoff-Tasmota/wiki/Martin-Jerry-MJ-SD01

Here's the parts list for my build below.

- 2 Pack Smart Dimmer Switch for Dimmable LED Lights

- Leviton 102-WP female plug (trimmed to fit)

- Hubbell 15-Amp-Volt White 2-Wire Plug (trimmed to fit)

Sonoff S26 FTDI Programing jig

After you print it out, you'll need to drill out the holes for the pogo pins and use hot glue to ensure that they do not short out on each other. Refer to this wiki for loading Tasmota onto the board github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-S26-Smart-Socket. The jig will gently snap onto the board. Make sure that the pogo pins are properly lined up before powering on the FTDI.

Here's the parts list.

- 6 - P75-E2 Spring Test Probe Pogo Pin 1.3 mm Conical Head 1.0mm (I recommend having spares)
- Female Header 1x40 2.54mm (trimmed down for an easy connection from the FTDI to the pogo pins)
- hot glue to hold the header/pogo pins in place

Here's the 3d design www.thingiverse.com/thing:3822216
