Ah they look just like the others they’re probably good to go appreciate the heads up thank you

walaj · May 10, 2020, 11:40pm

oooh! four gang tuya light switches.

(now comes the question of how to wire 2 and 3 way switches)

seanw18 · May 11, 2020, 12:28am

I wouldn’t use wiring. Do it with automation.

Are they certified, seems a few popping up of late all under different brands with a mixture of certs but they all look identical

exxamalte · May 11, 2020, 5:01am

I’m not an expert in assessing this, but at least they’re advertising the certification on the product pages (“Australian Certification GMA-504359-EA”), and published the certificates here: Certificates - S.R.L. TECHNOLOGY.

I am planning on converting a bunch of these Kogan Gen 2 USB Smart plugs to ESPHome. Some really dumb questions about these:

Do I need to tuya-convert first?
Can I do OTA for these first?
Can you please share your full config as I have no ESPHome devices so will be setting these up from scratch?

Thanks for your help everyone!

Hi Ben

Yes you will need to use tuya-convert first but you can load your esphome .bin files during that process.

Thanks Brad, much appreciated. I don’t have a Linux device, is there another way to use tuya-convert apart from opening the device itself?

walaj · May 11, 2020, 8:12am

Except I want the switches to be functional too…

I have one light, with 3 separate switches - at least these are all on a single gang set up.

I have one 4 gang switch which shares each of 3 lights with another gang.

My other issue is no-one seems to be keeping consistent with the glass panels - I have this everywhere else https://ae01.alicdn.com/kf/H4780d868deb5400e897334c1bab3368bt/US-standard-TUYA-WiFi-Smart-Switch-1-2-3-Gang-Wireless-Wall-Light-Touch-Switches-with.jpg although the srltech looks similar…

tuya-convert will run in docker, but whether it will run in docker on an OS other than linux I don’t know.

jasoncodes · May 11, 2020, 9:03am

Docker on non-Linux hosts won’t be able to SoftAP the Wi-Fi adapter. It might be possible to do some steps manually with a bridged network but that sounds painful to me.

When I wanted to flash a few devices I ended up using a Kali Linux image for VMware on my MacBook Pro with a RTL8192 USB Wi-Fi adapter in USB pass-through mode to the VM.

buzurk · May 11, 2020, 12:00pm

Anyone running the SRLTech stuff and can provide any feedback?

thecubical · May 11, 2020, 12:45pm

Got the fan controllers, as others have said they are quite loud at certain speeds, for the fan I have there is only one usable speed that doesn’t make a buzzing sound

BradAU · May 12, 2020, 12:09am

Personally I would get a Raspberry Pi to run tuya-convert rather than opening plugs up, it makes the process really easy and looking at the plugs I think you would do a fair amount of damage opening them.

Syrius · May 12, 2020, 12:42am

100% agree with this. i bought a rpi0w for next to nothing a while back and use it (via OTG Mode) to flash everything OTA.

waiting to do the next set… when they eventually get delivered by Aus Snail Post.

seanw18 · May 12, 2020, 7:15am

You could probably install tuya-convert on a persistent linux DVD or usb drive (i.e a live image).
Boot a PC off the DVD/USB and then install and run tuya-convert.
I’d go with a usb and ubuntu if you don’t know which linux to choose. Make sure you can boot from the usb.

Investigating the idea of getting solar, specifically before the end of the financial year. Has anyone got any specific products to recommend, something that you’ve been able to integrate into your smart home?
I note there is a Fronius integration which I hope would work with the inverters I see listed on various sites.

In addition, any specific installers people have dealt with and recommend? (in Melbourne)

tinglis1 · May 12, 2020, 8:49pm

An alternate to trying to get a solar system that is integrated into HA is to use a power monitoring system that does.
I use the IoTaWatt system and I get details of power usage on many different circuits in the house. You can do up to 10 ct clamps with IoTaWatt. All the information is pushed to influxdb and I draw the info from there into HA.

In my system I track the following

solar generation
grid in/out
ac
stove
lights
plugs

With the IoTaWatt you get current with direction, power and power factor. With that info you can start to work out a lot of what is going on in the home. For instance I can tell if the bathroom fans are being used by looking the the change in power draw and the power factor change. I also do a check to see if there are any dumb lights on after I run my goodnight script.

I also use Grafana to display info as it is very powerful and easy to setup with HA addons.

boc · May 12, 2020, 11:03pm

Thanks mate, appreciate the reply.
In contacting a few installers for quotes I’ve also made it clear I want power monitoring so it’ll be interesting to see what they come with - IoTaWatt may be one of them.

Hi all,

I have an Aeotec Z-Stick and many Aeotec dual nano switches.

Toggling light via wall switch has a delay of ~4 secs back to HA.
I spun up Zwave2Mqtt and it still had the large delay.

I have tried ALL sorts of settings for the nano switches. ZWave graph shows really good ping times. No security. Switching from HA is blazing fast. At my wits end.
Both 2.02 and 2.01 firmware, 3 to 4 seconds.

Does anyone else have these Aeotec switches?

Thanks
