Contact us

Pick the channel that matches what you need. Technical questions usually move faster on the forum or GitHub Discussions; commercial / press / partnership inquiries go to the dedicated email aliases below.

Direct email by topic

[email protected] — general questions, anything you are not sure where to send
[email protected] — technical / product support after purchase
[email protected] — bulk orders, OEM / private-label, distributor inquiries
[email protected] — press kit, media coverage, interview requests
[email protected] — vulnerability reports (PGP key on request)

Replies usually within 1–2 business days. We are a small team across multiple time zones — we read every email, but we batch responses.

Faster paths for technical questions

If you have a code or wiring question, the forum and GitHub get you a faster reply than email — usually within hours during European / US working hours.

GitHub Discussions — code, registers, examples, integration. Searchable; your question helps the next person.
Forum: forum.rbamp.com — community Q&A, project showcases, hardware install threads. (Forum launches with the Wireless line; until then GitHub Discussions is the right home.)
GitHub Issues — bug reports for the Arduino library, ESPHome component, or firmware (use the right repo).

Contact form

For inquiries that do not fit a topic email above:

Contact form coming online with the next deploy. Until then, email [email protected] and put the topic in the subject line:

[General] — general question

[Support] — technical support

[Press] — press inquiry

[B2B] — bulk / OEM

[Partnership] — partnership or collaboration

[Tool suggestion] — feedback on the docs, libraries, or tools

We will replace this placeholder with the Odoo form in the next iteration.
