Using all the defaults and RX/TX pins I get the following status:
Chip ID: 007a55a0
Hostname: ebus-7a55a0
Up time: 72
Free heap: 34736
ebusd connected: no
eBUS signal: no signal
eBUS initial signal: echo
And heater fails to f.49 error, according to manuals description is Short circuit on the eBus, overload on the eBus or on the eBus 2 of a voltage source with different polarity.
Any ideas how to debug this?
UPD: I've just found a note that voltage on EBUS should be 15-24 Volts, not sure how to properly archive this.
UPD: Looks like I miss the ebus adapter, it wasn't clear for me that ESP can't drive the bus directly.
Hardware:
NodeMcu v1.0
Protherm Skat 9
