Hi, I bought one of these, delivered last week, and I would seem to be having strange issues with it, so would welcome feedback....
It's ebus powered, but has a USB-c socket, so it can be separaetely powered. I got it plugged in configured with it's own unique address on my LAN. Ping is 100% reliable.
Telnet> o esp-ebus.local 3334 should produce what I assume ought to be a continuous stream of gibberish, on my screen - it does, but only at rare times. It was producing that gibberish for a couple of hours this morning, then it stopped, and nothing since. This working and then not working, is what I have witnessed for seveal days, since it arrived and I installed it.
When Telnet fails, the status web page becomes inacessible, as does the configuration webpage and everthing else in the device. Irrespective of when it appears to be working or not - it has several LED light's on the device, and these appear to continutue twinkling as normal.
Suspecting the ebus might not have the surplus current to properly drive it, I also tried powering it via the USB-c, which made no difference. My heating system, continues to operate as normal, completely unaffected by the device..
