node-red a full home automation example

-

 I'm not putting this publicly on github quite yet, though feel free to ask.

It is my attempt to put my home automation on a dashboard integrated with Alexa, Logitech Harmony and in these days of scary fuel bills my solar panels and consumption monitoring smart plugs.

You may or may not want my flows in all their glory, it is my house after all, but the following bits are of note.

  1. A reliable Tuya authentication mechanism.
  2. Solax solar cloud REST reading.
  3. A much extended set of harmony remote integration nodes compared to the original node-red-contrib-harmony repository I forked from.
  4. A way to read whether a Virgin TV box is on or off so a power toggle can be sent correctly.
  5. Hue lights control. Nothing special but might be easier than starting from scratch.
  6. A more useful version of the "sum" node that helps with power aggregation functions.
  7. Examples of using the alexa-node-red package so I can talk to Alexa and start node-red flows.
  8. A flow to turn an immersion heater on when there is enough surplus solar power.
  9. A harmony remote control layout that is easier and quicker than using the harmony app.
  10. Amp/TV modes that click between home theatre mode and sound from the TV. This uses two harmony activities but rigs harmony favourites that changing channels can maintain the current activity.
  11. Use of a new github repo https://github.com/marsjupiter1/node-red-contrib-tuya-auth which contains nodes for tuya  sign/auth/get/post.
  12. A subflow that can both use post and get and different tuya credentials and which handles re-authentication and the likely error conditions. This forms the heart now of the system communicating with tuya.
  13. A useful way of setting up devices across tuya accounts.

A reliable tuya authentication in node-red

-
In passing when working with tuya and node-red I had a couple of issues, the first one was conflicts with node-red-contrib-crypto-js-dynamic and node-red-contrib-crypto-js. node-red just doesn't seem clever when it comes to duplicate node names. In this example I have replaced the "hmac" function with a copy called mj_hmac. This can be replaced with the hmac from node-red-contrib-crypto-js-dynamic or failing that you will be unable to pass the tuya secret key as a parameter and will have to enter it in the hmac node dialog. The second issue is that tuya authorisation is on a fixed timeout of two hours.  If you refresh the key at 1 hour and 59 minutes it will only be valid for 1 minute. This flow keeps track of the time remaining and refreshes just after expiry. I have not seen errors since. However as a backup plan I do have sub flows that if they see an error reauthenticate. If anyone is reading and interested I can post them as well. [ { "id" : &qu

Arduino boards - what I wish I'd known when starting

-
 Arduino boards are an alternative to raspberry pi boards, for projects that involve custom hardware IO. For example a simple thermistor attached to take temperatures. For that kind of application a full blown computer like the standard raspberry pi range is obviously massive overkill. Well frankly for the purpose of reading a thermistor so is Arduino.  But they are cheap as chips. My starting point was 3x esp32 boards for £21.95 with inbuilt wifi and bluetooth. It's hard to argue at those prices. The boards are at that price clones, but that's the point really, it is an open hardware standard. As such there are a great number of variants. Code written for builtin wifi won't be quite the same for a board where you have added a wifi shield. So how do you program them? Remarkably the default language supported by the public IDE is C++ and as an important note, if you download this for windows, get the full version don't get what the Microsoft store offers you, it lacks ev
