The Yihi mod is the only one I'm currently aware of that allows control via Bluetooth.
Correction: The YiHi SXmini G Class V2 does not offer Bluetooth support. However, it does offer WiFi support (via a router or hotspot) using a web browser.
In your opinion. What's the best bluetooth mod right now? I'm not interested in flashy wastes of money for cosmetics. I was the tech and control for experimenting with new tanks, motars, pans. whatever the industry produces.
DNA, Dicodes, Yihi do not offer Bluetooth support. I do not know of any high-end mod that supports Bluetooth.
I attached the PDF user manual for the YiHi SXmini G Class V2. After reading the manual, to me, it looks like a lot of "flash" and "no real meat" with the device settings. It's settings are very (VERY) basic compared to any Dicodes or DNA mod.
No Yihi mod offers anywhere near the depth of settings a user has control over versus a DNA or Dicodes mod. Yihi settings are very basic. Yihi does offer free PC/Mac software (SXi-Tools) for their mods.
The settings a mod with a Dicodes chipset offers are very deep. DNA mods offer very similar settings.
None of the Chinese mod manufacturers offer what you are looking to do with tweaking deep chipset settings.
The Chinese mod manufacturers (GeekVape, Aspire, Innokin etc. etc.) business model = design a mod and get it out the door fast. They cater to the needs of the average vaper. And there is no issue with that at all, as there have been many decent Chinese mods over the years. Their mods are decent at running basic wattage mode. Compared to DNA, Dicodes or Yihi temp control - Chinese mods are a failure. None has implemented TC anywhere near the Big Three.
FWIW, many of the Chinese manufacturers mods released over the last number of years have completely dropped TC support. TC is not popular with the masses. TC is a niche market within the vaping industry. The majority of vapers want a mod that's easy to setup and use out of the box.
The Chinese did not create temp control vaping. As a result, their mods are mere childs play compared to DNA, Dicodes or Yihi.
Evolv created TC in 2014 with the DNA40 chipset. The German engineers at Dicodes, IMHO, took TC to another level. And that is not to say a Dicodes chipset is better than, or superior to, a DNA chipset.
It all comes down to personal preferences and what an end-user is looking for in a chipset.
You won't find what you are looking for in a basic Chinese mod. IMO, Chinese mods are the equivalent of a 1982 AMC Gremlin (very basic).
From a pure engineering standpoint, I would say a Dicodes chipset is the equivalent of an F-22 Raptor. Yes, the settings on a Dicodes mod are that deep.
IMO, a DNA mod is roughly the equivalent of a F/A-18 block III Super Hornet. DNA chipsets have deep settings but they are not as deep as Dicodes chipsets.
If someone was looking for a recommendation purely based on the depth of settings they have control over, then I would suggest a mod with a Dicodes chipset. There are more settings on a Dicodes mod versus a DNA mod.
If the requirement is to have a device with deep settings control, and an accurate ability to monitor a device in real-time, via a PC/Mac using a USB connection, then a DNA mod with Escribe is the only way to go.
Having said all that, I do like my Yihi, DNA and Dicodes mods. As to who offers the best TC implementation, that comes back to personal preference. Which of the three do I use the most? Dicodes and DNA equally. I haven't used my Yihi mod in quite some time.
Hope that helps!!!
