@m26872 said in Encapsulated transformers instead of traditional switching power supplies like Hi-Link:
for me the sunny season is too short.
I havn't yet tried to use solar batteries in winter so maybe I have the same problems (despite the fact that I'm living 3 degrees south of you), but I have backup solution for very cloudy winter days - regular battery charger.
@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze.
Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices.
And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant.

@Michael-Link I have been out of touch with MySensors for some time now and looking to slowly get back into it. I created this and a few other boards back in 2018 All of the GERBER files for this are in the "Design Files" tab. Those you should be able to send to JLC PCB or one of the other fab houses and have some made. This was designed to be used with 2 other boards that I designed. There was the processor board and the power supply board. The processor board was designed in a way that I could use a couple different switch boards. This one and a universal multi-switch board that had multiple configurations. If you look here you will see my other boards.
What I didn't quite figure out was how it operates independently as a regular light switch.
What I find most interesting is that this is 8 years old. There have been some incredible advances in the IoT world in that time. I was about to do a similar thing which morphed into an ESP-12F then added a touch screen. I call it the Universal Light Switch
Imagine this: All the switches are identical. Any switch can easily be configured to control up to five devices ... and then changed, on-the-fly, to control a different set of devices.
My design is part of a system that would require a controller (eg. Home Assistant), an MQTT broker, and receiving modules in the devices being switched. It's WiFI which assumes an access point.
The DIY ULS is under $20 and the off-the-shelf receiving modules are under $10. (About the cost of a non-networked dimmer switch) If one doesn't have the controller and MQTT broker, they can run on an old (5 years?) computer (which is cheaper than an old RasberryPi).
This project is a good one!
