I saw a video which said that now Sonoff sell their own Zigbee TRV the function will be added to iHost, but I bought smart TRV ages ago (MOES, which work on Tuya Platform): will the new TRV comparability extend to pre-existing Zigbee TRV or just the new Sonoff TRV?
I know from a conversation about confusing translations and so on with Tuya that they do a limited amount and just implement what the Moes Engineers tell them. I doubt all Zigbee TRV manufacturers have quite such a separate approach but it sounds like there is already an email describing the payload between Moes and Tuya and are a similar price category as the Sonoff TRV so I suspect your target audience may have this type.
