I just got a Viron EQ as well, while the Viron heat pump has Wi-Fi and a few other bits of my home plant have Wi-Fi, the EQ is an oddity with offering only Bluetooth.
Keen to help out but my programming skill is low and resources to do so and make boards right now even lower.
Keen to be able to get ORP and pH values out into HA for recording long term trends and notifications of alerts like “low salt”.
Being able to configure via HA doesn’t offer much unless to shift into manual mode out of programmed mode (Eg shift between manual on, manual off and auto mode). Because made in the future id sync EQ into manual on/off to be triggered by solar panel and total house consumption output.
