Hi Simon,
Welcome to the HA community!
It may be that English is not your first language, however your post as it stands may not get the best responses possible. Please don’t be offended, but a specific question, and more white-space punctuation would really help my tired eyes!
Can I ask you to have a look at this guide to help the community help you please?
Are you asking about if a specific integration supports controlling an Air-Source Heat Pump (ASHP) via MOD-BUS please?
So far I can see:
- MOD-BUS via RS485 Modbus - Home Assistant ?
- Reillo 12kw monobloc (possibly an Air-Source Heat Pump?)
- Sunsynk 8kw hybrid inverter and batteries?
