hi friend,

I need some help. I just trie to connect the ebus adapter2.2 today (buyed batch december 2018). But no success. i have installed the last firmware ebusd-esp Build: 20191229

I removed the extention board. connected my vaillant turbotech pro to the ebus terminal on base board. Powered the wemos using the usb interface.

on the ebus-esp i see: ebusd connected: yes (inactive) eBUS signal: no signal

Is there any polarity for the ebus on the base board. For info my ebus thermostat work perfectly, i have tried to install both in parallel and separately same issue. here the command used to launch the ebus damon ./src/ebusd/ebusd -d 192.168.2.225:9999 -l /var/log/ebusd.log --scanconfig --latency=20000 --address=01

Could you help?

The problem is solve. The ebus header was broken, and the yellow ligth still shine so it was diffifukt to found the issue.

Hello

Thanks for your answer.

I've mounted adapter on my own boardand in between times i solved the problem.

Few time ago I've bought some Wemos- differrent than usual.

I spoted that ESP was mounted directly to the main board, and without one transistor there, which just made shorts on RX line.

After change device works properly

Thanks
