Frequently Asked Questions - MIHO099 EnerGenie

How do I install the EnerGenie MIHO099 thermostat?

Installation requires a C-wire (24VAC). Follow the step-by-step instructions in the manual: turn off HVAC power, remove old thermostat, label wires, mount the base, connect wires to the corresponding terminals, attach the thermostat, and restore power. For detailed guidance, refer to the installation video on our website.

Does the MIHO099 support Apple HomeKit?

No, the MIHO099 supports Amazon Alexa and Google Assistant but does not natively support Apple HomeKit. However, you can use the EnerGenie app to control it from your iPhone.

What should I do if the thermostat is not connecting to Wi-Fi?

Ensure your Wi-Fi is on the 2.4 GHz band, not 5 GHz. The thermostat does not support 5 GHz. Also, verify that the Wi-Fi password is correct and that the router is within range. If the issue persists, reset the thermostat by pressing and holding the reset button for 10 seconds.

How do I reset the EnerGenie MIHO099 to factory settings?

Go to the Settings menu on the thermostat, select 'Reset', then 'Factory Reset'. Confirm with the code displayed. Alternatively, press and hold the reset button (small pinhole) on the back for 10 seconds.

Can I use the thermostat without a C-wire?

Yes, the MIHO099 can operate on 3 AA batteries (not included) if no C-wire is available, but some features like Wi-Fi and display backlight may be limited. For full functionality, a C-wire is recommended.

How often should I change the batteries?

If using batteries, they typically last 6-12 months depending on usage and Wi-Fi activity. The thermostat will display a low battery warning when replacement is needed.

Is the MIHO099 compatible with heat pumps?

Yes, the thermostat supports heat pumps (including aux heat) and can be configured for heat pump systems during setup. Select 'Heat Pump' in the system type settings.

What does the energy usage report show?

The EnerGenie app provides daily, weekly, and monthly reports on HVAC run time and estimated energy consumption. This helps you monitor and optimize your heating and cooling habits.

How do I clean the thermostat?

Use a soft, dry cloth to gently wipe the screen and body. Do not use water, cleaners, or abrasive materials, as they may damage the touchscreen.

The display is dim. How can I adjust brightness?

Navigate to Settings > Display > Brightness. You can adjust the brightness level or enable auto-brightness which adapts to ambient light.

Configuring the Thermostat

Display (1)

Swipe to view temperature, humidity and motion.

Manual On/Off control (2)

The thermostat may be set to either:

On - normal operation, powered on, controlling the heating, and reporting temperature, humidity, and motion.

Button shows green when selected, otherwise light grey.

Off - standby mode, powered on, not controlling the heating, but still reporting temperature, humidity and motion. Button shows dark grey when selected, otherwise light grey.

On and Off may be set from the MiHome server on the web browser, from the MiHome smartphone app device list, or from the thermostat page on the MiHome smartphone app.

Set the Target Temperature (3)

The target temperature may be set in 0.5°C steps using the slider control on either the web browser, or smartphone app. The temperature is shown on the slider itself (point 3) and the Target Temperature dial.

Comfort and Eco mode (4)

Comfort mode keeps the temperature control close to the target temperature, whereas Eco mode will allow the temperature to fall lower than Comfort mode before switching the boiler back on. This may be set from the Comfort/Eco selector on the main page. The margins for Comfort and Eco mode may be set in the settings section on either the web browser, or smartphone app.

Programmes (5)

Programmes comprise of an On time, an Off time, any or all days of the week, and a target temperature which together provide for controlled operation of the heating system. Multiple programmes may be configured for each thermostat. These programmes may be set on either the web browser, or smartphone app.

Name your thermostat (6)

The thermostat may be given a logical/descriptive name via the Rename Your Device section on either the web browser, or smartphone app.

Geofencing (7)

Geofencing uses the GPS technology on your smartphone (Apple or Android) to create a virtual geographic boundary, enabling software to perform a trigger activity when your mobile device enters or leaves a particular geographical area.

Configuring the thermostat – Settings page (8)

Temperature offset (9)

The thermostat may be given an offset in steps of 0.5° C to align with either other rooms or temperature measuring devices within your home. This offset may be set from the settings section on either the web browser, or smartphone app.

Humidity offset (10)

The thermostat may be given an offset in steps of 1% to align with either other rooms or humidity measuring devices within your home. This offset may be set from the settings section on either the web browser, or smartphone app.

Comfort and Eco temp margins (11 and 12)

See "Comfort and Eco Mode" on the previous "Configure thenThermostat" section.

Seasonal modes, Winter and Summer (13, 14, and 15)

During Winter, the heating control is normally required to be quite responsive to maintain the target temperatures, so the response time may be set accordingly (IO to 120 seconds in 1 second steps). During summer, battery life of the thermostat may be extended as the response time of the heating control may be set to a higher value (IO to 120 minutes in 1 minute steps).

Note: Setting the response time to less than one minute could significantly reduce battery life.

This summer and winter response times may be set from the settings section on either the web browser, or smartphone app.

TRV warmup time (16)

To allow any TRVs to reach their own designated target temperature, the heating can be set to continue heating for abdefined time after it has reached the target temperature at the thermostat location. This TRV warmup time can be set from the settings section on either the web browser, or smartphone app.

Reverse relay (17)

Depending on the boiler requirements, the relay may be left as default (Normally Open), or may be set to reverse operation (Normally Closed) This may be set from the settings section on either the web browser, or smartphone app.

eTRV Integration

For initial eTRV setup please refer to the eTRV instructions which are available on our eTRV product page.

All sections in eTRV Integration refer to the eTRV pages on the app. Repeat the following procedures as required for all eTRVs that are to follow the thermostat.

Follow Thermostat

You can enable any of your eTRVs to follow your Thermostat. By following the Thermostat, the eTRV will replicate and maintain the same target temperature as the Thermostat. To do this, select your desired eTRV from the dashboard. Select the last option on the page "Follow Thermostat"

Select your Thermostat from the list and save.

This returns you to the eTRV screen which now displays the Thermostat being followed, and the "Thermostat Overrides" option

Thermostat Overrides

An Override timer allows an eTRV that is following a Thermostat to ignore the target temperature of the Thermostat for a period. The timer will specify the time of the override, the days to activate the override and the desired temperature during this time. To set an Override timer select your desired eTRV, then select the "Thermostat Overrides" option.

Create the Override by defining the target temperature, times and days as required then save.

This will save the record showing an overview of the Override.

Selecting back returns you to the eTRV screen which now displays the number of Overrides created in the circle to the right of "Thermostat Overrides".

Unfollow Thermostat

From the eTRV page, select the "Following ..." option that shows the name of your thermostat. On the following page, select the option "Tap to unfollow" and save.
