Use ESP32-H2 to Build Smart-Connected Devices from Different Ecosystems

ESP32-H2 is Espressif Systems' first wireless-communication RISC-V SoC that supports both IEEE 802.15.4 (Thread/Zigbee) as well as Bluetooth 5 (LE). Thanks to the low-power-consumption features of the IEEE 802.15.4 standard and the integrated DC-DC converter, ESP32-H2 enables developers to build applications that actually decrease the power consumption of their devices even further.

[@adamrak7560]

when you need well behaved ADC with many channels, it means you need an external ADC.

[@TheModelmaker123]

@@adamrak7560 That's disappointing. The ESP 32 is an amazing device that is constantly getting better but the ADC needs work.

[@boontecklee592]

@@adamrak7560 It is not a question of how many adc channels one need as they are multiplexed. It is the accuracy of the core adc converter inside the SoC that should be improved with urgency. Why offer a lousy adc at all if Espressif has no plan to deliver a truly useful one?

[@EspressifSystems]

ESP32-H2, which leverages Espressif’s Wi-Fi and Thread capabilities, can be used to build Thread Border Routers that connect Thread and Wi-Fi networks. What’s more, ESP32-H2 can also be used to build Zigbee gateways, allowing users to control devices in the existing Zigbee network through the Matter protocol. Thus, with ESP32-H2, Espressif can now provide users with a full-featured Matter protocol solution, namely: interconnected Matter devices using i) either Wi-Fi or ii) Thread, as well as iii) Thread Border Routers and Zigbee gateways containing Espressif SoCs.

[@RBHMMX]

Does this device work with tasmota or is it possible in the future?

[@scout-ww4ck]

​@@EspressifSystems "i) either Wi-Fi or ii) Thread, as well as iii) Thread Border Routers and Zigbee gateways containing Espressif SoCs." So you mean, when I'm using H2 as zigbee gateway, I have to link it to another wifi board in order to have wifi connection?

@@scout-ww4ck you need a combination of SoCs for this purpose. ESP32-H2 will provide a Thread/Zigbee interface, and ESP32 (or ESP32-C3, or ESP32-S3, etc.) will provide a Wi-Fi interface. It is this kind of SoC combination that can function as a Thread Border Router or Zigbee Gateway. Hope this helps!

I'm trying to boycott as many Chinese sourced goods as possible, even though it means nipping at the heels of my personal interests, e.g. such as communications. Espressif are just one of those Chinese manufacturers I'm leaving on the shelf in order to lessen the impact of climate change. I'm trying the same strategy with US goods too.

[@EspressifSystems]

Hi Mark! Thanks for getting in touch. Very pleased to know you're interested in lessening your impact on the current climate crisis as much as we, at Espressif, are. Green technologies have always been at the heart of what we do at Espressif. Our low-power consumption SoCs are perhaps the most widely acknowledged results of our green policies. We also have a well-established program about wildlife protection: www.espressif.com/en/company/corporate-responsibility/wildlife-protection-program So, thank you for being on our side in fighting climate change.

[@MarkHopewell]

@@EspressifSystems I anticipated you would say this. However, my boycott is across all Chinese goods as it is across United States goods too. Until your country and the US as a whole change climate policy for the better, then I will be buying the very least Chinese and US goods as possible. Else, until recently, I quite liked the ESPxx series of devices but sadly, this is the end of the line for me in terms of this until climate policies are more aggressively pursued in your country. That said, this will no doubt hurt me more than it'll hurt you as I'm just a tiny weeny cog in the big commercial Chinese/US machine.

Unless many millions join in the boycott, there is little I can achieve alone. However, it's one of my hobbies down the pan but better than taking the climate down with it. If everyone boycotted these nations goods for just one month, maybe for a whole season, then we would get a better response from their governments to tackle climate change impacts more proactively. But as I said, I will make little difference acting alone.

@@MarkHopewell So the advertisements to push guilt to individuals has worked. Good for BigOil. Whilst i agree everyone has to do something, the big contributors to this situation wont care as they are funded directly by states and countries. So additionally to everyone doing their part (without fully stopping what they want to as it literally has almost no impact), we should also push politics to force companies to get better. They wont do it by themselves. The "free" market is a lie anyways.
