NOTE: from firmware 2.2.0, OpenSprinkler 3.x will support remote access via OpenThings Cloud (OTC) connection, thus it doesn't need port forwarding anymore. If you want add WiFi on top of that, go for it.Modified on: Fri, 30 Dec, 2022 at 11:21 AM In short, IMHO every home automation device (that speaks IP) should have an Ethernet port. My thermostat and window blinds are RS485, my security sensors are wired, my lights and fans are wired (Insteon). As wireless devices increasingly proliferate, the problem is only going to get worse.Īs to your question about using home automation devices, I have exactly two classes of devices in my home automation setup that are wireless: my Z-Wave door locks and my Harmony Hub. And if your device doesn’t support the latest version of WEP/WPA, then you’re forced to either downgrade the security on your WiFi just so that one device can connect to it, or you have to spin up another SSID or AP just for that device.Īnother issue with WiFi is the limited number of channels available if you live in a moderate density neighbourhood, you’re lucky if your neighbour’s AP isn’t stomping all over whichever channel you’re running on. Enabling compatibility modes slow down the WiFi for all clients, not just older devices. The same can’t be said of WiFi, when the user upgrades their AP, etc. I could plug an Ethernet device from 25 years ago into a modern Ethernet switch and it’d still work perfectly, without slowing down the rest of the clients. One of my biggest gripes about WiFi-only devices (even setting aside the reliability issue) is that WiFi standards evolve and are deprecated much more quickly than Ethernet. Lots of things are possible once you have an Ethernet jack (such as using a Ethernet to WiFi or Powerline bridge), but very little is possible when WiFi is your only option.
OPENSPRINKLER 3.0 SERIAL
– the microUSB on OpenSprinkler 3.0 is for serial communication only, it’s not a USB host.
We will probably not be able to continue supporting new firmware features for 2.0, 2.1 and 2.2 (not because we don’t want to, but because they have smaller microcontroller that cannot fit the large firmware any more), but 2.3 will definitely still be supported. – new firmware updates will NOT leave version 2.3 behind: new firmware features will always be available to both 3.0 and 2.3 (except hardware differences like sensor 2 which doesn’t exist on 2.3). – pin out and schematic of Expander 3.0 are now uploaded to Github: This is similar to using a WiFi adapter to enable WiFi access for OS 2.3 (as you know, OS 2.3 has only wired Ethernet and no WiFi), except it’s done the reverse way.
OPENSPRINKLER 3.0 HOW TO
Also, if the issue is mainly to bring WiFi to a place where WiFi doesn’t exist, we have a one-page document explaining how to use a portable WiFi access point (which costs just about $15 to $25) to serve as an interface between Ethernet and WiFi: On the product webpage, we did specify that if you absolutely still want the older version 2.3, we can still ship them, it’s just that there is generally 2-3 week lead time since we don’t regularly stock these any more. As a computer science researcher, I trust WiFi myself. How do you avoid using WiFi at all? I really think a lot of concerns about WiFi are overstated. Those who don’t trust WiFi for reliability: I am kind of surprised: you use WiFi-only gadgets on a day to day basis, like your mobile phone, your laptop. If you look around, almost all modern gadgets and Internet of Things are WiFi only - Nest, Amazon Echo, wireless power sockets, garage door openers, your mobile phones, your laptops… Very few devices still provide Ethernet jack. In the rare cases of weak WiFi signal, you can add a WiFi range extender to boost the WiFi signal (and ESP8266 has a version with external antenna to boost the reception considerably). WiFi is the future, and I don’t think security is any problem, since ESP8266 supports all modern WiFi security standard. I honestly think it’s more reliable compared to the Ethernet chip. We’ve used the ESP8266 WiFi chip on all our recent products, such as OSBee, OpenGarage.
