The thing is can you test one at -30 and tell me if it still works before I buy one and test it in our cold chamber ?

We have not tested mPower down to that low of a temperature; therefore, I would not suggest using it for your situation if it's mission critical. We do not plan to build more mPower for outdoor purpose. It's unlikely that we will retest mPowers to extend the range on spec.
From my personal experience, it's always a good practice to put equipments inside an environmental box when placed outdoor. I dont' know if your -30 deg C is measured inside a box already. A box usually provides some sort of insolation. Not sure if it'll raise the temp up 20 deg to fall inside the operational range (-10 - 45).
I have seen people put a small light inside the box to raise the temperature internally so equipments can operate properly (not mFi related products).
