I have a LG Therma V - installed 2020. Controls and data are not great - even if improving in later models. 

I don't have the ability to setup Home Assistant and so far have not found another good option.

I came across Passiv Smart Thermostat which are aimed at many heat pumps

I thought I'd add here as potentially of use to others?

Thanks @tim441. Interesting timing, as Passiv are a currently an advertising partner on Renewable Heating Hub, so I think I'll partially hijack your thread and transform it into a "Passiv Smart Thermostat – Help & Forum Support" where people can ask questions and I can get the team at Passiv to answer questions anyone has about their products and how they're complimentary to heat pump systems.

How do people like this? I was looking for thermostats that are for ASHP that do not have an ongoing subscription fee 

I also want to know if this can be used with a Grant R290, and if so, do I need the Aerona Smart Controller or could this replace it entirely?

@petch I’ve not come across anyone yet that’s used these thermostats so can’t comment on that, but @fraser-allison or @will-h might be able to comment on compatibility with your Grant heat pump.

@petch We are not yet compatible with the R290 from Grant but we do support their R32 units. 

You can find all the models we are compatible with here.

We regularly add new integrations, so hopefully we will support the Grant R290 in the not too distant future!

And you are correct that we don't charge any subscription fees - all the features of the Passiv Smart Thermostat (flow temperature, time of use tariff and solar PV optimisation) are included for free!
