This is a ShellyLib Flow that reads Shelly Device CoAP Broadcast and outputs to status to Mqtt Broker. This also, can reads Mqtt Subsciptions to Set Shelly Switch Devices

Use at your own risk.
This is Demo/Example of a Node-Red Shelly-to-Mqtt Flow using factory Standard Firmware. Shelly Cloud must be turned ON.
It works very well for me, it does what I want.
This is "beta" release, updates may be coming.
Goals and Implementation:
1. Maintain use of Factory Firmware
2. Continue Using the Shelly Cloud
3. Support; Shelly-1, Shelly-2, and Shelly_HT
(these are the only Shelly device types that I have access)
4. Provide Shelly Device Status Reports to MQTT Broker
5. Allow MQTT Topic Customization
6. Allow for Custom MQTT Topic per Device via NickNames
7. Allow single point of NickName Admin for Node-Red
and MQTT Broker.
8. Implement MQTT Last-WILL and Connection Status
9. Retain all MQTT data
10. Subscribe to MQTT Broker with "mqttPrefix" and then Decode and
end "on/off" REST command to Shelly Switches.
11. Allow use of: Shelly Device Names, NickNames, or IP Address
for Shelly Switch Control
12. Allow use or NOT of "/relay" within NickNames, and
MWTT Published commands.
13. Provide User Option to Set MqttRetain flag
There maybe better methods to implement this flow, Contributors Welcome.
Note:
All examples and configurations; show my "mqttPrefix"
which must be configured before use
Note:
This CoAP Shelly Decoder uses a "Brute Force" method
of decoding, because; it is easy, simple,
costomizable, and the Shelly CoAP packets are of
known content.
Note:
The example nickNames the "User Perference" node are
some that I use, they must be changed to be useful.
To Use:
Requirements: NodeRed Install "node-red-contrib-moment" via Manage Palett
Note: This NodeRed Flow Tab must be "Enabled", it is provided "Disabled"
Customize the "MQTT Pub" Node
Set Mqtt Publish Broker Address and Port
Set up Birth, Close, and Will Topics in Messages Tab
Set Mqtt Broker Authentication as necessary
Customize the "MQTT Sub SET" Node
Set Mqtt Subscribe Node wiht Broker, Port, and Topic
Set Mqtt Broker Authentication as necessary
Customize "User Preferance" Node:
Set up use.nickName to "true" or "false"
Set up mqttRetain to "true" or "false"
Set up NickNames
Set up Mqtt topic Prefix
Customize "ShellyTic" Node
Set the desired Time Tic Interval
Customize "Date/Format" Node
Set Time Zone and Local Date Format
The Debug and LOG outputs Nodes can be removed,
or just left turned off, as desired.
Note:
Shellys are very "chatty" on CoAP on the network
as can be seen via the LOG output.
Note:
The ShellyLIb collects IPA from MQTT traffic of Shelly Device for later
use as Aliases and REST Commands.
Example MQTT Pub Commands (each group does the samething):
On/Off is NOT case sensitive, topic is case sensitive
-
mosquitto_pub -t ebconpri/shelly/SHSW-1/32C849/relay/0/Set -m off

TBD:
Represent Shelly-2 Power Better.
List Discoverd Devices as New.
Remove 404 Chat back from Node-Red UDP/CoAP.
Maybe add JSON output.
