didn't know they can do that without mqtt... how they communicate between them, which protocol?

According to the official Tasmota site for device grouping: "UDP multicasts, followed by UDP unicasts if necessary, are used to send updates to all devices so updates are fast. There is no need for an MQTT server but all the devices in a group must be on the same multicast network."

Great video, not new to electronics in general but new to the HA world. Looks like the shelly would be perfect and non-intrusive for my needs - I'm in a condo. This might be silly, but do you have a recommendation for the short wire between the shelly and the switch? I won't need 12ft but also want it to be proper. Its been a long time since I've done anything electrical like this and I dont have scraps of anything anymore. Thanks again for the awesome and detailed video.

You are most welcome! For the Shelly connections I just took a small scrap piece of 14/2 Romex and cut short leads from that to make short jumpers for the switch and power connections. So, 14 gauge would be recommended. Whatever wire you use, it needs to be rated for the expected amps that will pass through the circuit. The good news are that they are very short runs, but you don't want to risk the wire overheating. The Shelly relays are rated for 15 or 16 amps (depending upon model) so I'd say as long as you use 14 gauge wire or larger, you should be fine. But as I stated, I am not a licensed electrician but since 14 gauge is what is used for most US residential situations, as long as you stick with that, it should be acceptable. Good luck with your Home Assistant journey. Don't hesitate to reach back out if I can help out in any way.

Fantastic video! I got one light switch to control my bedroom overhead light but wanted to add two switches to control the bedtable lamps instead, but without taking away the overhead light for when I sell the house. This would let me do it without having to create new switches for my lamps! I cannot than you enough for this video.

Thanks. Tasmota switches and relays are a great way to 'rewire' switches and outlets without the need to alter any existing circuits or "in the wall" wiring. And as you mentioned, it also makes it easy to restore everything to "default" configuration whenever you decide to sell your house. Glad you found the video helpful. Let me know if you run into any particular questions or issues along the way.

Great video as always! I have a question for different topic. My esp32 with wled comsuming power while the leds turned off. What is the thing that I need to make the OFF really an OFF? I tried using a smart plug but it's not the best solution.
@ResinChemTech
Жыл бұрын
It is true that LEDs still draw a small amount of power when "off". One solution is what you have done... use a smart switch or plug to kill power to the entire system, including the ESP32. But this does have the drawback of the device being unavailable in Home Assistant or for use in any automations unless that automation also powers on the system first... which does add a slight delay due to the time it takes for the ESP32 to boot up. If you wish to truly kill the power to the LEDs while keeping the ESP32 powered on, WLED supports use of a relay that will switch the power to the LEDs off/on. You can find information on using a relay with WLED here: kno.wled.ge/features/relay-control/ Personally (and this is JUST my opinion), the amount of energy draw by a string of 200 LEDs when "off" is around 1 watt (per the WLED page). Here where I live, the cost of a kWh is about $0.13. That means that 200 LEDs that are off but drawing power would cost me about $1.13 for the entire year for that. If I spend $5.00 to add a 5V relay to shut those LEDs off, it would take approximately 4.3 years of cost savings just to cover the cost of the relay. And this doesn't count any additional energy used by the relay itself. But there are other reasons for killing the power to the LEDs I suppose. Safety could be one... I do kill the AC power to the entire power supply for my outdoor LEDs when they are not is use. But this is because they are outside and if not in use, it is just safer to kill the power. You may have additional reasons. But I think when people believe they are "saving money" by killing the power to the LEDs, they haven't really done the math. If you have an install with 1,000s of LEDs that are going to be turned off for a significant amount of time throughout the year, you might be able to save a few dollars each year. But in my example of 200 LEDs above, it would take me approximately 5 years of "off" time to realize about $1 of actual energy cost savings after the cost of the relay was recouped. But again this is just my personal opinion and everyone has their own reasons for wanting to save that power. Thanks for watching.

While Tasmota has an amazing number of features, I think that device groups are one of the best features, since once installed it allows you to easily "rewire" how switches and outlets work in your house without actually rewiring them. Thanks for watching!

Ahh, I am immediately struck by the humorous thought that revoking a cardinal sin has a cost of two 3-way-smart switches. I am not in any way saying I disagree or disapprove, it was just humorous to this old man! Keep up the great work and keep them videos coming!

Well, this is the way it should have been done in the first place. But it was one of my first "smart" devices and had been in place for years. And I've done so much "preaching" in my other videos about not removing existing functionality and yet I still had this old device in place doing just that... despite numerous times when I wish I could turn the light on with a simple wall switch. So unlike many of my other videos, this was a project I needed to do for myself and I decided to make it into a video in case it might help someone else. Actually, I ended up leaving it like I did towards the end of the video where one switch controls one lamp and the other controls the other lamp. I'm not sure why there were two three-way switches so close together anyway... but that's how they were wired. Using Tasmota let me repurpose one of those switches for better independent use. But as always, thank for watching and I greatly appreciate the comment.

After actually watching the complete video, you have given me a new understanding and appreciation of device groupings, especially with Tasmota. One question since I am such a noob, if Tasmota uses MQTT and the broker is not available I suppose you only lose the benefits of the grouping, am I understanding that correctly?
@ResinChemTech
Жыл бұрын
Actually, for Tasmota groups, MQTT is not required. So the grouping/syncing works completely standalone. Only your WiFi is needed so the groups still work even if your MQTT broker goes down (or you don't even have one). MQTT is needed however for Home Assistant integration. Even though there is a native Tasmota integration for Home Assistant, it still uses MQTT "under the hood". So, in short, you can do everything I showed in this video even if you don't have MQTT (well, except for the voice control... as that uses Home Assistant in my case).

If you don't want to manually enter all the YAML to integrate the Tasmota device, then you need the Tasmota integration installed in Home Assistant. However, since the Tasmota device uses MQTT discovery for the integration, you also need the MQTT integration. So... you always need the MQTT integration. You can then manually create all the MQTT entities via YAML... or you can install the Tasmota integration as well, which will create all the entities for you without any manual YAML code.
