These are various scripts and tools published by others I have packaged up for use as Home Assistant addons. I generally try to keep images up-to-date with changes, so you should be able to add the repository to your instance and be able to quickly install if you wish to use them.
- rtl_tcp - plug an rtl sdr into your suporvised homeassistant instance and install this add-on to allow other add-ons (or anything) to access it on port 1234.
- metermon - An add-on version of this, slightly modified for homeassistant usage. Outputs each meter's messages that rtlamr detects to metermon/meeter-id topics, ready for your mqtt sensor platform entries in config to bring them in to ha.
- Mimic3-tts-server - A Mimic3 local tts server for Home Assistant.
