hi all
i am currently reviewing which heat pump to install in my house
its absolutely critical for me to have local control via HA so i can interface with the octopus API and my solar and batteries ect.
specifically im looking at what they call hydronic or air to water heat pumps. im not looking at air to air or aircon as we call it.
if anyone knows any brands with HA plugins please share!
im trying to build a list\1
Hi,
My ASHP gets installed next month, and after a lot of searching, simply, I’m not sure.
The Octopus Cosy units looked to be cloud API only, so I went for a Daikin Altherma on the basis that “most” have a serial port, and some have options for a expensive and possibly crap local WLAN module.
My plan is to try a Fakin ESP32 module on the serial port and see if the Daikin aircon protocol is similar to the Altherma.
Will it work? Ask me in a month… 
Solar and battery storage inverters seem even worse, with even Platinum quality integrations needing manufacturer “permission” to connect (EnPhase needs an API key, Fox ESS have some reports of poor support, GivEnergy seem to be TCP Modbus).
Worst case, my hope is the Octopus API might be a last cloud resort for ASHP+PV+batt+EVSE.
It looks like UK HMG may be changing the MCS grant conditions to allow air-to-air heat pumps, opening the door to heating and cooling - something that would have been useful but not ÂŁ7500 useful!
This forum has a lot of good searchable information, but manufactures seem too trigger-happy in updating firmware to lock owners out of their own hardware and changing APIs, so the situation changes. No, I don’t like it either. 
If this helps, 
this post!
