#tasmota

Honestly the best solution imo would be a Tasmota-compatible client (the bar is very fucking low. just a button and an http request???) on android and desktop but all android apps that I tried are shit and/or contain ads. (this is only gonna get worse in the future im sure) I just want a little button I can press from the comfort of my bed honestly.

I have a VPS and maybe a rpi 3b+ I could use, but would prefer not to. (so Home Assistant is def off the table.) Surely I'm not the first person to want a very minimal setup?

Almost tempted to set up nodered, could easily integrate that with a remote and/or my door sensor as well but ehhhh. Alternatively I could go the very simple route and wire up a button to an ESP, hang that next to my bed.

Hey les techies ! J’espère que vous passez de bonnes vacances malgré la situation… Pour ma part je bricole sur Raspberry et ESP histoire de me créer un petit système domotique full DIY. D’ailleurs je vous ferais sûrement quelles articles/vidéos à ce sujet (Raspberry PI, Domoticz, MotionEye, ESP8266 et ESP32 avec firmware Tasmota) dites-le dans les commentaires si cela vous intéresse !

In the field of power electronics, AC Voltage Regulator is a type of power converter that is used to convert a fixed AC voltage into variable AC Voltage. Variable AC power supplies can be used in most of the day-to-day applications like heaters (for altering temperature settings), Fans, Dimmer Circuits, etc.

For modern-day microcontroller-based Smart Home appliances, understanding the interface between digital electronic to power electronic becomes a necessity, hence this article provides a detailed overview of AC Voltage Regulators and the necessary design parameters.

I wrote this post explaining why you might want to reflash your plugs.  Now lets see how you do it.

I purchased a set of generic plugs that work with the Smart-Life app : https://amzn.to/2WNxYLV

The first step is to make a plug reflasher.

For this, I used a Raspberry Pi 3 Model B V1.2 with  Image : 2020-08-20-raspios-buster-armhf-full.img

Connect a network cable (or do this via console on device not on SSH) Turn off WIFI by clicking on wifi symbol and disabling WIFI

git clone https://github.com/ct-Open-Source/tuya-convert cd tuya-convert

Now we install the bits of software it needs with ./install_prereq.sh

And start the reflasher : ./start_flash.sh

It is handy to open another window and see the log files cd tuya-convert tail -f scripts/*.log

Answer the questions to say you are sure you know what you are doing.

To put a plug in the right mode to flash it you normally press the on/off button for about 10 seconds.   When plug is detected pick ‘flash with Tasmota.bin’ Wait 30-40 seconds for plug to be flashed.  When it is finished it will say ‘Do you want to flash another device’

Connect to the new Wifi device form your phone. Tasmota-1234 Enter your Wifi name and password in the top two boxes (AP1 SSID and Password) Click save

Find the new plug on your wifi.  I do this by going to my router and looking at the ‘client list’.  It will be called tasmota-1234 or will be the one that has the shortest DHCP lease time (30 seconds or so).  When you have its IP address, go to that address in your browser.

Click configure Module and pick a plug type.  If you cannot find anything lcose, go for ‘Generic (18)’.  For the plugs I have, I found ‘GoSund SP1 v23 (55)’ works fine. Click save and then Main menu.

Click Configuration and MQTT.  This is how you will link it to Home-Assistant. For Host, enter the IP address of your control server.  Te IP address stays as ‘1883’. For Client, give it a name like ‘Plug-01’. User and Password are for the MQTT user in Home-Assistant.  You should already know this as you set it up (see earlier post on MQTT). For Topic – Give it a unique name.  I didn’t change this at the start and found multiple plugs going on and off each time I clicked on one in Home-Assistant.  Leave the ‘full topic’ as it is and click SAVE and Main menu.

Click on Configuration and ‘Other’ and set a web admin password.  You will need this to get back to this screen. (when you try the login user will be ‘admin’ and the password will be what you set here).  Give it a friendly name like Plug-01 and put a tick in the box that says ‘template’

When you buy a device like a plug or lightbulb and it comes with the statement ‘no hub needed’, what this actually means is the company runs a hub (or set of servers) for you so you do not have to.

Why would you not want to stay with a system like this ?

- What if their server goes down ? What if this means you cannot turn on or off your lights or plugs.

- What if they close down ?

- What if they upgrade in a years time and it breaks your old device ?

Then of course there is the other issue... 

- Do you really want a company, maybe in a different country to have full control of your lights ?  They could turn them on and off when they feel like it.  They could monitor when you have your lights on.  They could even use the plug to jump onto your network and look at local files, tvs, or computers !

Reflashing is the process of changing the firmware (the control software) to a new version that you control locally.
